INTRODUCTION
Features
and
Benefits
This manual provides information on the features, instal-
lation, and operation of the Punch 4040 DSM and 4080
DSM Amplifiers. We suggest you save this manual for
future reference.
We strongly recommend you have your Authorized Rock-
ford Fosgate Dealer install your new Punch 4-channel
amplifier. If you do choose to install the amplifier yourself,
please be sure to read the entire manual before beginning.
The Rockford Fosgate 4-Channel automotive stereo power
amplifiers provide state-of-the-art sound in cars, vans,
boats, or wherever a high current
12
volt power source is
available.
“Discrete Surface Mount” (DSM)
technology is utilized
in the crafting of all of our Punch amplifiers. This process
provides greater ruggedness and consistency of both
components and layout. Already used heavily in aerospace and industrial applications, this technology is also
highly advantageous in the hostile automotive environment.
Low Level Input Senstivity.
The Punch 4-channel ad-
justable input circuits are designed to match almost any
music source. The amplifiers will drive most normal
speaker types.
Punch Equalization.
This circuit is designed to compensate for the acoustic inadequacies of the automotive
environment. This patented circuitry will correct for the
poor bass response and natural high frequency roll-off
inherent in the world of automotive stereo. The result is
full-range sound without the unpleasant changes in the
mid-range sound produced by most tone control and
equalizer circuits.
Active Electronic Crossover Modules
built-into the
4040 and 4080 features 12 dB/octave Butterworth filters.
The independent crossover points in these plug-in modules allow for various configuration possibilities.
4
Real Time Power Protection (RT.P.P.) allows
for the
greatest power output under all load conditions. When
output reaches an unsafe level it will be reduced, unlike
current limiting which often causes premature protection
or failure to protect at all.
To get a better understanding of the Punch let’s take a
closer look.
CONTROLS AND FEATURES

End Caps
This section describes the various controlsand features of
the Punch 4040 DSM and 4080 DSM amplifiers.
Top View of Amplifier and End Caps
The cast aluminum
heatsink
of the Punch 4-Channel is
designed for high performance cooling. The raised design
of the housing allows cables and wires to run underneath
the unit. This provides for greater wiring flexibility and
protects the cables from damage caused by excessive
heat and bending.
Interchangeable end caps conceal the wiring and input
cables, giving the amplifier a clean, “stealth” look.
Also
incorporated, is a holding dimple built into the end cap.
This small feature enables the cap to be held in place while
being mounted.
The end caps are secured to the housing with flush
mounting, captive screws.

Mounting
Four (4) custom, round, hex screws included in the acces-
Screws
sory pack hold the unit in place. These screws are covered
when the end caps are installed.

The Punch 4-Channel is turned on by connecting the blue
remote turn-on wire to the source unit’s “Accessory” or
“Auto Antenna” lead, either of which will go to +12 volts
when the source unit is turned on.
The LED illuminates when the unit is activated.
These connectors are used to supply power and ground
to the amplifier and accept 12 gauge
-
8 gauge wire.*
These gold-plated terminal blocks connect the Right/Left
Front and Right/Left Rear channel outputs to the speak-
ers and accept wire sizes from 8 gauge through 18 gauge.
Gold-plated connectors are immune to corrosion that can
cause signal deterioration.

cludes high quality power
and speaker wire, gold plated RCA
interconnecting cable and other products to complete your
installation. Ask your Authorized Rockford Fosgate Dealerabout

This switch allows you to use the front input to drive both
Front and Rear channels. Switching to Rear position
allows you to run separate Front and Rear inputs. This
eliminates the need for a “Y-adapter” when using the
amplifier in a bi-amplified or
4-Channel
mode.
This switch enables you to easily invert the phase of the
Rear channels on the amplifier without having to disconnect the speaker wires. See the wiring diagram on page
17 for use.
These controls adjust the amount of treble and bass
response desired. To increase the amount of response,
turn the controls clockwise; to decrease, turn the controls
counterclockwise. Note that there are separate Bass and
Treble controls for Front and Rear channels.
These controls are factory preset to 500 millivolts to
match most head units and are variable from 100 millivolts
to two volts. (More than likely they will not need
adjusting. )
If just a little volume from the source unit drives the
amplifier into distortion, reduce the input gain controls so
that the distortion doesn’t start until the source volume is
at about
3/4 of its rotation. Note that there are separate
Front and Rear gain controls.

Pass-Thru
Connectors
The amplifier’s signal input, female, RCA jacks should be
connected to the source unit’s signal outputs with highquality RCA cables. The connectors have been plated in
gold to eliminate the possibility of corrosion that can cause
signal deterioration.
These pass-thru connectors allow you to daisy-chain an
additional Punch amplifier without running an additional
set of RCA cables from the front of the vehicle to the rear
amplifier location. The crossover module in the Pass-Thru
RCA circuit allows the daisy-chained amplifier to be con-
figured independently of the Front and Rear channels for
low pass, high pass or full range operation.
The Pass-Thru signal isderived by summing the Front Left
and Rear Left inputs to create the Left output, and summing the Front Right and Rear Right input to create the
Right output. This provides constant output regardless of
the source unit fade position.
INSTALLATION CONSIDERATIONS
This section focuses on some of the vehicle considerations for installing your new Punch 4-Channel amplifier.
Checking your battery and current 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.
Carefully read and understand the instructions before
attempting to install the amplifier.
2.
For easier assembly, we suggest you run all wires
prior to mounting your amplifier in place.
3.
Use only quality connectors for making connections.

Rockford
Fosgate Dealer for
