INTRODUCTION

The Punch 160.4 and 240.4 are 4-channel amplifiers which can
deliver 160 watts and 240 watts RMS respectively. Both amplifiers
utilize a 2/4-channel input switch to eliminate the need for signal
splitters. A pair of internal XCard crossovers allow the amplifiers to be
configured for use with many popular system designs without the
added cost of external processors. The Punch 160.4 and 240.4 are
powerful 4-channel amplifiers with integrated features which are
offered at a competitive price.

We strongly recommend you have your Authorized Rockford Fosgate
Dealer install the new Punch amplifier. If you do choose to install it
yourself, please be sure to read the entire manual before beginning.

TECHNICAL DESIGN FEATURES

– 2 –

◆ TOP AZ (Tracking Operation Pre-Amplifier Zone)

The

TOPAZ

(Tracking Operation Pre-Amplifier Zone) circuitry solves
ground loop noise problems common to automotive amplifier design.
This innovative new development allows vastly improved isolation of
the input signal grounds from the power supply ground of the
amplifier. This is accomplished by allowing the source unit to control
the potential “environment” of the entire input structure or “zone” of
the amplifier. This process improves the noise rejection of the
amplifier by 30-40dB – an astounding 30-100 times better than
amplifiers without TOPAZ.

THE RESULT: Elimination of troublesome ground loop noise between
source and amplifier.

◆ TRANS•ANA

(TRANSconductance Active Nodal Amplifier)

The

TRANS•ANA

(TRANSconductance Active Nodal Amplifier) is a
circuit that allows the audio signal to pass through the amplifier at low
voltage. The signal is directly level-shifted to the fixed high voltage
rails via a pair of driver transistors. Signal linearity is assured by an
active node formed by the drive transistors at ultrasonic frequencies.
This allows amplifier performance similar to trans•

nova

which is
highly stable and linear while utilizing the advantages of a non­floating power supply.

THE RESULT: An extended frequency bandwidth accurately supplied
to the output stages of the amplifier.

◆ DSM (Discrete Surface Mount) Technology

The

DSM

(Discrete Surface Mount) manufacturing process combines
the advantages of both discrete components and integrated circuitry.
Rockford Fosgate is the only American amplifier manufacturer to have
invested millions into this process. DSM components differ from
conventional discrete components in three ways. They are more
compact, more rugged, and they efficiently dissipate generated heat.
Using them wherever appropriate allows the advantages associated
with discrete circuitry to be retained while also providing room for
both highly advanced processing features and generous PC board
copper paths where needed. Their short lead-out structures allow
maximum audio performance and highest signal-to-noise ratios to be
obtained in amplifiers of desirable package size without resorting to
“amplifier-on-a-chip” shortcuts. These advantages are shown in Figure

1.

THE RESULT: Fewer connections, improved reliability, shorter

signal paths, superior signal-to-noise ratio and awesome sonic
performance.

◆ XCard (Internal Crossover)

The Punch amplifiers utilize internal active crossovers. These
crossovers have many performance advantages such as using
discrete components for exact frequency adjustments which are
far superior to potentiometers. Additionally, the XCard can be
configured for high-pass, low-pass and full range operation. With
slight modifications, many crossover frequencies and slope con­figurations can be achieved.

THE RESULT: Increased system design flexibility with a precise
electronic crossover without the limitations of conventional

potentiometer designs.

◆ NOMAD (NOn-Multiplying Advanced Decision)

The Punch amplifiers use an

analog computer process

to maximize
safe output power under all operating conditions. Rockford Fosgate
pioneered and developed

RTP

(Real Time Protection), a crucial

element in the performance edge of our amplifiers. The innovative

NOMAD

(NOn-Multiplying Advanced Decision) system is the most
sophisticated version of this technique ever used, bringing previously
unavailable levels of accuracy, stability, temperature immunity and
reliability to this critical process. NOMAD makes advanced decisions
based on device voltages to precisely control the awesome levels of
current available in the output MOSFETs to safe values – but only
when absolutely needed.

THE RESULT: Extremely fast protection system that always protects
the amplifier and never degrades the sound.

◆ MOSFET Devices

Rockford Fosgate is one of the few manufacturers in the sound
community to utilize MOSFET devices in both the

power supply

and

the

output stages. MOSFET

(Metal Oxide Semiconductor Field Effect

Transistor) devices offer several important inherent advantages over

the 30 year old technology of bi-polar design. These advantages
include: thermal stability, switching speed, ultra low output imped­ance and wider bandwidth linearity. In addition, MOSFETs operate
very similar to vacuum tubes in which they are more linear than
bipolar transistors. However, MOSFETs can deliver the midrange
clarity without the limitations of transient response and high fre­quency phase shifting normally associated with tube operation.

THE RESULT: Operational characteristics similar to vacuum tubes
without the performance limitations of tube designs.

DESIGN FEATURES

1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch
amplifier dissipates heat generated by the amplifier's circuitry. The
inherent advantage of casting provides a 30% improvement of
cooling over conventional extrusion heatsink designs.

2. End Caps – The unique end caps conceal the wiring and input cables,
giving the amplifier a clean “stealth” look.

3. Speaker Terminals – The heavy duty, gold-plated terminal block
connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG.
These gold-plated connectors are immune to corrosion that can
cause signal deterioration.

4. Power Terminals – The power and ground connectors on the Punch
amplifier are gold-plated and will accommodate up to 8 AWG wire
maximizing the input current capability of the amplifier.

5. REM Terminal – This gold spade terminal is used for the auto power/
remote turn-on of the Punch amplifier.

INSTALLATION CONSIDERATIONS

This section focuses on some of the vehicle considerations for installing
your new Punch amplifier. Checking your battery and present sound
system, as well as pre-planning your system layout and best wiring routes
will save installation time. When deciding how to lay out your new
system, be sure that each component will be easily accessible for making
adjustments.

Before beginning any installation, be sure to follow these simple rules:

1. Be sure to carefully read and understand the instructions before
attempting to install the amplifier.

2. For safety, disconnect the negative lead from the battery prior to
beginning the installation.

3. For easier assembly, we suggest you run all wires prior to mounting
your amplifier in place.

4. Route all of the RCA cables close together and away from any high
current wires.

5. Use high quality connectors for a reliable installation and to mini­mize signal or power loss.

6. Think before you drill! Be careful not to cut or drill into gas tanks,
fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring
when working on any vehicle.

7. Never run wires underneath the vehicle. Running the wires inside the
vehicle provides the best protection.

8. Avoid running wires over or through sharp edges. Use rubber or
plastic grommets to protect any wires routed through metal, espe­cially the firewall.

9. ALWAYS protect the battery and electrical system from damage with
proper fusing. Install the appropriate fuseholder and fuse on the
+12V power wire within 18” (45.7 cm) of the battery terminal.

10. When grounding to the chassis of the vehicle, scrape all paint from
the metal to ensure a good, clean ground connection. Grounding
connections should be as short as possible and always be connected
to metal that is welded to the main body, or chassis, of the vehicle.

The following is a list of tools you will need for installing the Punch
amplifier:

Allen wrenches 9/64" & 3/32" (included) Voltmeter
Wire strippers Battery post wrench
Electric hand drill w/assorted bits Wire cutters
Wire crimpers Assorted connectors

MOUNTING LOCATION

The mounting location and position of your amplifier will have a great
effect on its ability to dissipate the heat generated during normal opera­tion. The design of our cast aluminum heatsink serves to easily dissipate
the heat generated over a wide range of operating conditions. However,
to maximize the performance of your amplifier, care should be taken to
ensure adequate ventilation.

Trunk Mounting

Mounting the amplifier vertically on a surface with the fin grooves running
up and down will provide the best cooling of the amplifier.

Mounting the amplifier on the floor of the trunk will work but provides less
cooling capability than vertical mounting.

Mounting the amplifier upside down to the rear deck of the trunk will not
provide proper cooling and will severely affect the performance of the
amplifier and is

not

recommended.

Passenger Compartment Mounting

Mounting the amplifier in the passenger compartment will work as long
as you provide a sufficient amount of air for the amplifier to cool itself. If
you are going to mount the amplifier under the seat of the vehicle, you
must have at least 1" (2.54cm) of air gap around the amplifier's heatsink.

Mounting the amplifier with less than 1" (2.54cm) of air gap around the
amplifier's heatsink in the passenger compartment will not provide proper
cooling and will severely affect the performance of the amplifier and is

not

recommended.

Engine Compartment Mounting

Rockford Fosgate amplifiers should

never

be mounted in the engine
compartment. Not only will this void your warranty but could create an
embarrassing situation caused by the ridicule from your friends.

– 8 –

Amplifiers will put an increased load on the vehicle's battery and
charging system. We recommend checking your alternator and battery
condition to ensure that the electrical system has enough capacity to
handle the increased load of your stereo system. Stock electrical systems
which are in good condition should be able to handle the extra load of
any Rockford amplifier without problems, although battery and alterna­tor life can be reduced slightly. To maximize the performance of your
Rockford Fosgate amplifier, we suggest the use of a heavy duty battery
and an energy storage capacitor.

BATTERY AND CHARGING

WIRING THE SYSTEM

CAUTION: Avoid running power wires near the low level input cables,
antenna, power leads, sensitive equipment or harnesses. The power wires
carry substantial current and could induce noise into the audio system.

• For safety, disconnect the negative lead from the battery prior to
beginning the installation.

Configure the internal XCard crossovers prior to installation. (Refer to
page 14 for more information.)

1. Plan the wire routing. Take care when running signal level RCA cables
to keep them close together but isolated from the amplifier's power
cables and any high power auto accessories, especially electric
motors. This is done to prevent coupling the noise from radiated
electrical fields into the audio signal. When feeding the wires through
the firewall or any metal barrier, protect them with plastic or rubber
grommets to prevent short circuits. Leave the wires long at this point
to adjust for a precise fit at a later time.

2. Prepare the B+ cable for attachment to the amplifier by stripping 5/8"
of insulation from the end of the wire. The use of 8 gauge power cable
can interfere with the installation of the end caps. Proper wire dress
can prevent this from occurring. To prevent the wire from fraying, strip
the insulation at a 45° angle. Insert the bared wire into the B+ terminal
with the long side of the insulation on the top. Bend the cable down
at a 90° angle. Tighten the set screw to secure the cable in place.

– 9 –

3. Punch 160.4
Trim the power cable to within 18" of the battery and install the
protective rubber boot packed with the fuseholder over the end of
the wire. Strip 3/8" of insulation from the wire and insert it into the
end of the fuseholder, then crimp it in place. Slide the rubber boot
into place to cover the connection. Use the section of cable
trimmed earlier and connect it to the other end of the fuseholder.

Punch 240.4

Mount the fuseholder within 18" of the battery using two (2) #8
screws. Disassemble the fuseholder. You should have 2 black
plastic end caps, 2 gold-plated fuse clips, a plastic spacer and the
fuseholder body. Trim the amplifier power cable to reach the
fuseholder and strip the wire 3/8". Slide one of the end caps over
the wire (narrow end first) and insert the wire into one of the fuse
clips. Tighten the set screw. Screw the black end cap to the
fuseholder body to secure the cable. Use the section of cable that
was trimmed earlier and connect it to the other end of the
fuseholder. Install the plastic spacer in the fuseholder and attach
the cable to the fuseholder body.

NOTE: The B+ cable MUST be fused 18" or less from the vehicle's
battery. Install the fuseholder under the hood and prepare the
cable ends as stated above. Connections should be water tight.

4. Strip 3/8" from the battery end of the power cable and crimp the
large ring terminal to the cable. Use the ring terminal to connect
to the battery positive terminal. Do not install the fuse at this time.

5. Prepare a length of cable to be used for the GND connection. Strip
5/8" of insulation from the end of the cable as described previously
and connect to the appropriate terminal of the amplifier. Prepare
the chassis ground by scraping any paint from the metal surface
and thoroughly clean the area of all dirt and grease. Strip the other
end of the wire and attach a ring connector. Fasten the cable to the
chassis using a screw.

– 10 –

6. Prepare the REM turn-on wire for connection to the amplifier by
stripping 1/4" of insulation from the wire end and crimping an
insulated spade connector in place. Slide the connector over the
REM terminal on the amplifier. Connect the other end of the REM
wire to a switched 12 volt positive source. The switched signal is
usually taken from the source unit's auto antenna or the accessory
lead. If the source unit does not have these outputs available, the
recommended solution is to wire a mechanical switch in line with
a 12 volt source to activate the amplifier.

7. Connect the source signal to the amplifier by plugging the RCA
cables into the input jacks at the amplifier.

8. Connect the speakers. Strip the speaker wires 5/8". Insert the bared
wire into the speaker terminal and tighten the set screw to secure
into place. Be sure to maintain proper speaker polarity.

DO NOT
chassis ground any of the speaker leads as unstable operation may
result.

9. Perform a final check of the completed system wiring to ensure that
all connections are accurate. Check all power and ground connec­tions for frayed wires and loose connections which could cause
problems.

After the final inspection is complete, install the power fuse and
enjoy listening. During the initial listening period, you may need
to “fine tune” any phasing and level settings within your particular
vehicle. To aid in this procedure, play a track with high musical
content and cruise around your neighborhood. After fully evaluat­ing the transient response of your system and making any final
adjustments, all your neighbors within a 1 mile radius will assume
that you have just successfully completed another upgrade to your
audio system for which they will probably spill thumbtacks on
your driveway.

USING PASSIVE CROSSOVERS

A passive crossover is a circuit that uses capacitors and/or coils and is
placed on speaker leads between the amplifier and speaker. The
crossover delegates a specific range of frequencies to the speaker for
optimum driver performance. A crossover network can perform one of
three functions: High-Pass (capacitors), Low-Pass (inductors or coils)
and Bandpass (combination of capacitor and coil).

The most commonly used passive crossover networks are 6dB/octave
systems. These are easy to construct and require one component per
filter. Placing this filter in series with the circuit will reduce power to
the speaker by 6dB/octave above or below the crossover point
depending on whether it is a high-pass or low-pass filter. More
complex systems such as 12dB/octave or 18dB/octave can cause
impedance problems if not professionally designed.

Passive crossovers are directly dependent upon the speaker's imped­ance and component value for accuracy. When passive crossover
components are used in multiple speaker systems, the crossover's
effect on the overall impedance should be taken into consideration
along with the speaker's impedance when determining amplifier
loads.

CAUTION: The Rockford Fosgate amplifiers are not recom-

mended for impedance loads below 2Ω stereo and 4Ω bridged
(mono) loads.

USING THE XCARD

The crossover functions are controlled through the use of an XCard
and can be set for high-pass, low-pass or full range operation. Each
crossover card has two faces: one face operates Full Range, the other
has arrows to indicate the edge for selecting HP (high-pass) or LP (low­pass) operation. Orient the card with the desired operating edge,
indicated by the arrow, toward the socket terminals inside the

amplifier. Firmly, but carefully, plug the card into the socket.

The crossover point can be altered by changing the 4 resistor values.
Use the following formula to select the appropriate resistor value to

be placed on the XCard.

DYNAMIC POWER MEASUREMENTS

About the Dynamic Power Measurements

The Audio Graph PowerCube is a test instrument used to measure the
output of an amplifier in accordance with IHF-202 industry standards.
The IHF-202 standard is a dynamic power measurement and was
developed as a means of measuring power in a manner that best
represents the real world operation of an amplifier. Many manufacturers,
including Rockford Fosgate, at times will measure amplifier power into a
fixed resistor (4 ohm, 2 ohm). While this method is useful in some types
of evaluation and testing, it is not representative of an amplifier that is
connected to a speaker and playing music.

Music

Music is dynamic; the sound waves are complex and constantly chang­ing. In order to simulate this, the IHF-202 standard calls for the input signal
to the amplifier to be a 1kHz bursted tone. This signal is input (on for 20
milliseconds) and reduced 20dB for 480 milliseconds. The signal is
gradually increased in level until the amplifier's output exceeds 1% Total
Harmonic Distortion (THD). At 1% distortion becomes audible, there­fore, any power produced above that level is considered

not usable

. Many
manufacturers represent their amplifiers' output power in excess of 10%
distortion. They use many names for this measurement, such as Total
Maximum Power or Maximum Output Power. This is not indicative of the

actual usable output power

.

Listening to Loudspeakers - Not Resistors

A loudspeaker is not a resistor. A resistor's value (resistance measured in
ohms) is fixed. A loudspeaker's impedance is dynamic. It is constantly
changing in value, dependent upon the frequency of the input signal.
Therefore, measuring power with the amplifier loaded into a 4 ohm
resistor is not the same as measuring power with the amplifier connected
to a 4 ohm speaker. Most people do not listen to music through a resistor.

A 4 ohm speaker may experience a drop in impedance 4-6 times lower than
its nominal (printed) impedance. A speaker will also create phase shifts in
the signal that is passed through it. These phase shifts happen because a
speaker is an inductor (voice coil) and a capacitor (compliance of the
surround/spider), as well as a resistor (voice coil wire).

To simulate a speaker the Audio Graph PowerCube measures output
power into 20 different loads. It tests at 8 ohms, 4 ohms, 2 ohms and 1
ohm. Each of these impedances is also tested at –60°, –30°, 0°, +30° and
+60° phase angles. These different impedances and phase angles repre­sent the shifts in impedance and phase that can occur in a typical
loudspeaker.

– 33 –

Information Cubed

The data acquired in the testing procedure is then graphed in the form of
a 3-dimensional cube. Hence the name PowerCube.

The

Phase Angle

is expressed on the horizontal axis, the

Output Voltage

is presented on the vertical axis and the

Impedance

is displayed on the Z

axis.

Output Power,

in watts, is listed on the left hand side for each

impedance at each phase angle.

What is an Amplifier?

An amplifier by definition is a voltage generating device, recreating the
signal which is input to it identically but with increased volume. It will be
connected to a reactive load (the speaker). The impedance of this load and
phase of the signal passing through the load will vary, dependent upon the
frequency of the input signal (music).

Therefore, a perfect amplifier will be able to maintain the same output
voltage regardless of load characteristics and will not alter the signal it is
reproducing. A perfect amplifier when measured by the AudioGraph
PowerCube would present data that forms a perfect cube. Unfortunately,
amplifiers are not perfect. The laws of physics generally prevent it. A great
amplifier is about the best one can hope to attain.

As you can see by the PowerCube and as you will experience by listening,
your Punch amplifier is a GREAT AMPLIFIER!

interrupteur 2/4 canaux qui élimine le besoin d'un séparateur de signal.
Une paire de cartes de filtrage interne permet de configurer l'amplificateur
afin d'être utilisé dans la plupart des configuations sans dépense
supplémentaire.

Nous vous recommandons fortement de faire installer votre nouvel
amplificateur Punch par un dealer agréé Rockford Fosgate. Si vous
décidez néanmoins de l'installer vous-même, assurez-vous de lire
l'entièreté de ce manuel avant de commencer.

INTRODUCTION

Montage dans le coffre

Monter l'amplificateur verticalement avec les rainures de haut en bas ce
qui lui permet de refroidir plus facilement.

Montage dans l'habitacle

Monter l'amplificateur dans l'habitacle ne pose aucun problème, du
moment qu'il y ait assez d'air pour le refroidir. Si vous montez l'ampli
en dessous du siège, prévoyez 3 cm d'air autour du radiateur.

Installation

Pour votre sécurité, déconnectez la borne négative de la batterie du
véhicule avant de commencer l'installation.

Terminal B+

Il est impératif qu'il y ait un fusible sur le câble pour la connexion à la
masse. Préparez le châssis en grattant la peinture de la surface métallique
et nettoyez la saleté et l'huile. Attachez le câble au châssis avec une vis.

Terminal GND

Préparez une longueur de câble pour la connexion à la masse. Préparez
le châssis en grattant la peinture de la surface métallique et nettoyez la

Wir empfeheln Ihnen, Ihren neuen Verstärker, von einem unserer
autorisierten Rockford Hzuandler einbauen zu lassen. Sollten Sie den
Verstärker selber einbauen, so beachten Sie bitte diese Hinweise, bevor
Sie mit dem Einbau beginnen.

EINLEITUNG

Im Fahrzeugkofferraum

Der vertikale Einbau der Endstufen, das bedeutet, daβ die Kühlrippen
von oben nach unten verlaufen, gibt dem Verstärker die beste Kühlung.

Auf der Beifahrerseite

Sollte der Verstärker auf der Beifahrerseite montiert werden, so ist es
sehr wichtig, für eine ausreichende Kühlung zu sorgen. Sollte der
Verstärker z.B. unter dem Beifahrersitz montiert werden, sollte dem
Kühlkörper mindestens ein Luftspalt von 3 cm bleiben, um so für eine
ausreichende Kühlung zu sorgen.

Einbau

Zur Sicherheit klemmen Sie den Negativ-Pol der Batterie während des
gesamten Einbaues ab.

B+ Anschluss

Die Plus-Leitung MUβ ca. 40 cm nach dem Plus-Pol der Batterie abgesichert
sein. Preparieren Si die Kabellängen und montieren Sie den Sicherungshalter
im Motorraum. ALLE Verbindungen müssen wasserdicht sein.

GND Anschluss

Preparieren Sie Ihr Kabel für die Negativ Leitung (Erdung). Preparieren
Sie die Anschluβstelle des Erdungskabels, indem Sie das Metall gründlich
reinigen und vom Lack befreien. Befestigen Sie nun die Erdung an dieser
Stelle mit einer Schraube.

ATTENZIONE: SI PREGA DI LEGGERE LE SEGUENTI ISTRUZIONI PER
L'INSTALLAZIONE DI QUESTO PRODOTTO. IL NON SEGUIRLE POTREBBE
RISULTARE SERIAMENTE DANNOSO PER LA PERSONA O PER IL VEICOLO.

I Punch 160.4 e 240.4 sono amplificatori 4 canali in grado di erogare
rispettivamente 160 e 240 watt RMS. Entrambi questi amplificatori
impiegno uno switch di selezione 2/4 canali evitando l'impiego di
sdoppiatori di segnale. Una coppia di XCard interne permette agli
amplificatori di essere impiegati nelle configurazione piú in voga senza
richiedere l'impiego di costosi processori esterni. I Punch 160.4 e 240.4
sono potenti amplificatori con caratteristiche integrate che li rendono
molto appetibili, anche da un punto di vista di prezzo.

Raccomandiamo fermamente di fare installare il vostro nuovo
amplificatore da un installatore autoizzato Rockford Fosgate. Se scegliete
di procedere da soli con l'installazione assicuratevi di leggere
attentamente tutto il manuale prima di procedere.

INTRODUZIONE

Nel Bagagliaio

Montando l'amplificatore su una superficie in verticale con le alette
direzionate dall'alto verso il basso si garantirá un miglior raffreddamento
dell'amplificatore.

Nell'abitacolo

Montare l'amplificatore nell'abitacolo si avrá un funzionamento regolare
se si garantisce un flusso d'aria sufficiente. Per l'installazione sotto un
sedile, é necessario avere uno spazio di almeno 3 cm attorno a tutto
l'amplificatore.

Installazione

Per sicurezza, scollegare il polo negativo della batteria dell'auto prima
di iniziare l'installazione.

Terminale B+ (cavo positivo)

Il cavo positivo deve essere protetto da un fusibile a non piú di 45 cm
dalla batteria. Terminare il cavo e installare il fusibile nel vano motore.
Tutte le connessioni devono essere a prova d'acqua.

Terminale GND (cavo negativo)

Decidere la lunghezza del cavo e terminarlo. Preparare la massa
grattando la vernice dal telaio dell'auto ed eliminando tracce di olio o
sporco. Fissare il cavo di massa al telaio con una vite.

DOVE POSIZIONARLO

– 48 –

Terminale REM (Consenso di accensione)

Collegare il cavo REM ad un positivo presente solo ad autoradio
accesa (normalmente il cavo pilota dell'antenna elettrica o il cavo
accessori dell'autoradio). Se la sorgente non dovesse essere
equipaggiata con queste uscite, la soluzione raccomandabile é di
inserire un interruttore su un cavo positivo e connettersi
all'amplificatore.
