Introduction
Rockford engineers designed the Punch multi-channel amplifiers to with-
stand the rugged automotive environment while delivering superior sound
quality in a flexible, reliable, and efficient package. TRANS•ana is a low
voltage circuit in the preamp stage of all Punch multi-channel amplifiers
that lets the music sound crystal clear and very real, even when played at
high volume levels. This is matched with TOPAZ, a unique grounding cir-
cuit used to eliminate noise problems associated with car audio systems
and their installation. Flexibility is accomplished with the use of high-level
inputs and a built-in crossover. The use of a protection circuit called
NOMAD, along with MOSFET and DSM (Discrete Surface Mount) and our
innovative MEHSA heat dissipating technology improves amplifier efficien-
cy. The result of these components give the Punch amplifier awesome
sound quality in a “Bullet Proof”package.

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. Speaker/Power Terminals –The heavy duty, gold-plated terminal block
connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG
and are immune to corrosion that can cause signal degradation. The
Punch 600, 5-channel also utilizes a barrier strip that will accept #8
spade lugs or bare speker wires sized from 12-18 AWG.
3. REM Terminal –This spade terminal is used to remotely turn on and
turn off the amplifier when +12V DC is applied.
4. Signal Input Switch –This switch allows the amplifier to be driven with
either 2 or 4 pairs of inputs. The Punch 600, 5-channel allows the
amplifier to be driven with either 2, 4, or 6 pairs of inputs.
5. RCA Input Jacks –The industry standard RCA jacks provide an easy
connection for signal level input. They are gold-plated to resist the sig-
nal degradation caused by corrosion.
6. High Level Inputs –The high level inputs use a detachable connector
terminated with 20 AWG leads. These inputs should be used if the
source unit has only speaker line (high level) outputs and not RCA out-
puts.
7. RCA Pass-Thru Jacks –The Pass-Thru provides a convenient source for
daisy-chaining an additional amplifier without running an extra set of
RCA cables from the front of the vehicle to the rear amplifier location.
8. Gain Control –The input gain control is preset to match the output of
most source units. It can be adjusted to match output levels from a vari-
ety of source units.
9. Punch Bass –The Punch Bass helps correct for acoustical deficiencies
in the listening environment by helping reproduce full range sound
without adding excessive boost. The Punch Bass control is a narrow
band adjustment centered at 45Hz variable from 0dB to +18dB.
10. Internal Crossover –The internal crossover is a 12dB/octave
Butterworth filter selectable for High-Pass (HP), Full Range (FULL), or
Low-Pass (LP) operation. The Punch 200/400, 4-channel amplifiers
utilize a fixed 80Hz crossover. The Punch 600/800, 4-channel and
Punch 600, 5-channel amplifiers utilize a crossover variable from
50Hz to 210Hz with the Sub channel operating at 24dB/octave.
11. LED Power Indicator –The LED illuminates when the unit is turned on.

Installation Considerations
The following is a list of tools you will need for installing the Punch
amplifier:
Voltmeter Wire strippers
Electric hand drill w/assorted bits Battery post wrench
17' (5 m) Red Power Wire Wire cutters
12' (4 m) Remote Turn-On Wire Assorted connectors
1.5' (45 cm) Black Grounding Wire Wire crimpers
–7 –
This section focuses on some of the vehicle considerations for installing
your new Punch amplifier. Checking your battery and present sound sys-
tem, 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 begin-
ning 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 cur-
rent 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 plas-
tic 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 fuseholder and appropriate fuse on the +12V
power wire within 18”(45 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 connec-
tions should be as short as possible and always be connected to metal
that is welded to the main body, or chassis, of the vehicle.

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 maxi-
mize 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 strongly 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
strongly not recommended.
Engine Compartment Mounting
Rockford Fosgate amplifiers should never be mounted in the engine com-
partment. Not only will this void your warranty but could create an embar-
rassing situation caused by the ridicule from your friends.
–8 –

Battery and Charging
–9 –
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.
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.
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 pre-
vent short circuits. Leave the wires long at this point to adjust for a pre-
cise fit at a later time.
2. Prepare the Power 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 inter-
fere 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.
3. Strip 3/8" from the battery end of the power cable and crimp a large
ring terminal to the cable. Use the ring terminal to connect to the bat-
tery positive terminal. Do not install the fuse at this time.

4. Prepare a length of cable to be used for the ground connection. Strip
5/8" of insulation from the end of the cable as described above and
connect to the appropriate terminal of the amplifier. Prepare the chas-
sis ground by scraping any paint from the metal surface and thorough-
ly 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 non-
anodized screw and a star washer.
5. Prepare the REM turn-on wire for connection to the amplifier by strip-
ping 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 ampli-
fier.
6. Securely mount the amplifier (with supplied screws) to the vehicle or
amp rack. Be careful not to mount the amplifier on cardboard or plas-
tic panels. Doing so may enable the screws to pull out from the panel
due to road vibrations or sudden vehicle stops.
7. Determine the number of inputs needed to drive the amplifier and
move the input switch to the desired setting.
8. Connect the source signal to the amplifier by plugging the RCA cables
or high level inputs into the input jack(s) at the amplifier.
9. Connect the speakers. Strip the speaker wires 5/8" and insert into the
appropriate terminal on the amplifier. 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.
10. 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 from
road vibrations.

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 (combi-
nation of capacitor and coil).
The most commonly used passive crossover networks are 6dB/octave sys-
tems. These are easy to construct and require one component per filter.
Placing this filter in series with the circuit will reduce power to the speak-
er 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 profes-
sionally 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 Punch
amplifiers are not recommended for impedance loads below 2Ωstereo
and 4Ωbridged (mono) loads.
