1. Gold Plated RCA Jacks

All input and output RCA jacks are gold plated. The gold plated
finish resists tarnishing and corrosion from interfering with the
signal quality.

2. Power Terminals

The B+, Rem and Gnd connections are made using gold plated
screw terminals on the barrier strip. The gold plating resists tarnish
and corrosion and maintains connection integrity. The terminals
allow easy connection of the power wires through the use of forked
lugs or bare wire up to 12 gauge. The barriers help prevent shorting
from frayed wires.

3. LED Power Indicator

The LED, located by the input jacks, provides a visual indication of
the status of the crossover, lighting when the unit is turned on.

4. PROCards

Crossover filter functions are determined by the use of plug in
cards. Each card can be configured for high-pass, low-pass and full
range operation. Resistors on each module determine the operat­ing frequency.

5. Input Mode Switch (3X and 5X only)
When the input mode switch is in the two channel position the
front input jacks feed all the filters. When set to the four channel
position, the front and rear input jacks feed the respective filters.
Front and rear channels are summed for the non-faded filter.

– 3 –

6. Phase Switch (3X and 5X only)
The phase switch allows easy invertion polarity on the non-faded
output to optimize sound quality.

7. Mounting Holes

The crossover must be mounted on a flat surface. Two mounting
holes in the bottom are used to secure the crossover.

8. Fusing

The crossover has a 1/2 amp AGC fast blow power protection fuse.
If it is necessary to replace the fuse, use only the same type and
rating or the warranty may be voided.

INSTALLATION CONSIDERATIONS

This section focuses on some of the vehicle considerations for
installing your new Punch Electronic Crossover. 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. Be sure to carefully read and understand the instructions before
attempting to install the crossover.

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 electronic crossover in place.

4. Route all of the RCA cables close together and away from any
high current wires. this will help reduce noise.

5. Use high quality connectors for a reliable installation and to
minimize signal or power loss. See your Authorized Rockford
Fosgate Dealer for wire enhancements.

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 for 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 a fuse holder 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. Use of a continuity meter will confirm a proper
ground.

– 5 –

MOUNTING AND WIRING THE
ELECTRONIC CROSSOVERS

The information below describes the various considerations for
mounting and connecting the active crossovers. For additional infor­mation see the wiring diagrams beginning on page 10.

We recommend mounting the crossover as close to the amplifier(s) as
possible.

The B+ (Power) supplies power to the unit. Connect this terminal to
a constant +12 Volt power source by way of an in-line fuse.

The GND (Power Ground) grounds the unit. Connect this terminal to
the chassis of the vehicle. When grounding the unit be sure to scrape
all paint from the metal to ensure a clean electrical connection.

The REM (Remote Turn-On) turns on the unit by way of a +12 Volt
supply source. Connect this terminal to the source unit’s “Amplifier”
or “Auto Antenna” lead, either of which will go to +12 volts whenever
the source unit is on.

If your source unit does not have either a Remote or an Auto Antenna
lead (or if the Auto Antenna goes down during tape operation), we
recommend installing a switch to control the unit manually.

INPUT/OUTPUT LEVELS & CONNECTIONS

The Punch Electronic Crossovers are designed for preamp (input up
to 2VRMS) levels. Net gain in the crossover is unity. (Output levels are
equal to input levels.)

When connecting the input and output terminals be sure to use high
quality shielded interconnecting RCA cables.

• Connect source unit's OUTPUT jacks to the desired crossover
INPUT jacks.

• Connect the desired crossover’s OUTPUT jacks to the Amplifier’s

INPUT jacks.

SELECTING THE PROC ARDS

The Punch 2X is shipped with 100Hz cards. The 3X is shipped with
100Hz and blank programmable cards and the 5X is shipped with
100Hz, 6.5kHz and blank programmable cards. The following cards
are available factory built from your Authorized Rockford Fosgate
Dealer.

XM50 50Hz
XM70 70Hz
XM100 100Hz
XM150 150Hz

XM275 275Hz
XM400 400Hz
XM4.5k 4.5kHz
XM6.5k 6.5kHz

XM200 200Hz

Each card can be used for high-pass, low-pass or full range operation.
The mode of operation is determined by the orientation of the ProCard
in its socket. These same PROCards are used in other Rockford
Fosgate products.

The following illustrations show the PROCards shipped in the Punch
2X, 3X and 5X. As configured, out of the box, each card is set for full
range operation.

USING THE DUAL FILTER

The Punch 3X and the Punch 5X both have Dual Filter sections. The
Dual Filter is a two stage cascaded filter which uses two PROCards.
The first card determines the initial action and the second, the
subsequent action. The most common usage would be to use a low­pass module in the first position followed by a high-pass module in the
second to build a bandpass function. By using two cards of the same
action at the same frequency, the filter slope is increased to 24dB per
octave. Both sockets must be used for a simple 12dB per octave filter.
Install the card in the second position for full range operation.

INSTALLING THE PROC ARDS

The operation of each filter section is determined by the use of plug
in cards. These multifunctional cards are available for a multitude of
operational frequencies, and their orientation in the socket deter­mines their function. Each socket has a blank plastic side which
positions the card against the spring loaded contacts. The front, or
active, face of the card is marked with arrows to indicate which edge
plugs into the socket. Orient the card with the chosen face toward the
contacts and plug it into the socket of the appropriate filter operation.
The rear face of the card is for full range operation and either edge can
be used.

APPENDIX A

BUILDING A CUSTOM PROCARD

The 3X and 5X both ship with blank cards which can be assembled
to select any frequency you need for your system's design. Each card
is built using 4 capacitors and 4 resistors, the value of the resistors
determines the operating frequency. The custom cards are also
available as model number XM00 from your Authorized Rockford
Fosgate Dealer. The following section has instructions on assembling
the card. The PC Board is fragile and extra care should be taken to
avoid damage.

Items Needed:

1. Soldering Pencil
40 to 60 Watt electronic soldering iron

2. 60/40 resin core solder

3. Solder Braid - to keep surface free of excess solder

4. Capacitors - Each card uses four .022µF capacitors. These should
be metal film capacitors with a minimum rating of 16 volts.

5. Resistors - Each card uses four resistors. The resistance is deter­mined by the operating frequency (refer to the following chart).
These can be either 1/8 or 1/4 Watt, 1% or 5% tolerance.

6. Wire Cutters

Refer to the following illustration for component placement. Install
the resistors, from the full range face, and fold the leads slightly toward
the inside of the board to hold them in position. Solder the resistors
in place and use the solder braid to remove any excess solder. Install
the capacitors in the same manner. Trim the component leads.
Examine the board carefully to ensure there is no solder splashed,
paying particular attention to the contacts on each edge. Make sure
that the leads do not interfere when plugging the card into the socket.

WARRANTY INFORMATION

Rockford Fosgate warrants all electronics to the original consumer/purchaser to
be free from defects in materials or workmanship for a period of three (3) years.
We will cover parts and labor provided the product was purchased from an
Authorized Rockford Fosgate Dealer. This warranty does not apply to any product
on which the seals and/or serial number have been broken, removed, tampered
with, defaced or altered in any manner. This warranty applies only to the original
consumer/purchaser and is not transferable.

Electronics found to be defective during the warranty period will be repaired or
replaced at Rockford Fosgate’s discretion. Repaired or replaced electronics will
be covered by the balance of the original warranty period only. Rockford Fosgate
shall not be responsible for any incidental or consequential damages resulting
from a defect in electronics. Some states do not allow the exclusion or limitation
of incidental or consequential damages, so the previous limitation may not be
applicable.

The warranty does not cover any appearance item, any cost or expense related to
the removal or reinstallation of the product, any accessory used in conjunction
with the product, damage to the product resulting from alteration, accident,
misuse or abuse, or improper installation. This warranty does not apply if the parts
or labor, which would otherwise be provided without charge under this warranty,
are obtained from any source other than Rockford Fosgate or an Authorized
Rockford Fosgate Service Center.

This warranty is the only express warranty and does not create any implied
warranties. Rockford Fosgate limits its obligations under any implied warranties
under state laws to a period not to exceed the written warranty period. Some states
do not allow limitation on how long an implied warranty lasts, so the above
limitation may not apply. This warranty applies only to products sold in the United
States of America or its possessions. For warranty outside the U.S.A., please
contact the nearest Authorized Rockford Fosgate Dealer. This warranty gives the
consumer specific legal rights, and the consumer may have other rights which vary
from state to state.

A defective product must be shipped prepaid to the Authorized Rockford Fosgate
Dealer from which the consumer purchased the product or to the Rockford
Fosgate factory in Tempe, Arizona in the original factory carton or equivalent. Any
shipping loss or damage will be borne by the consumer or the consumer’s shipper.
A consumer returning a product to the factory should call [phone] for a
Return Authorization Number. All shipments shall be clearly marked with the
Return Authorization Number on the outside of the shipping carton.
