I NTRODUCTION
Rockford engineers designed the Punch 2-channel amplifiers to withstand
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 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 circuit used to eliminate noise
problems associated with car audio systems and their installation. Flexibility
is accomplished with the use of a built-in crossover. The use of a protection
circuit called NOMAD, along with MOSFET and DSM (Discrete Surface
Mount) technologies improve amplifier efficiency. The result of these
components give the Punch amplifier awesome sound quality in a “Bullet
Proof” package. An explanation of these technologies, most of which are
exclusively designed and patented by Rockford, are described in the
Technical 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. Speaker/Power Terminals –These gold-plated connectors are used for
the connection of speaker and power wire and are immune to corrosion
that can cause signal degradation. The Punch 120 and Punch 160
utilize a barrier strip that will accept #10 spade lugs or bare speaker and
power wires sized from 10-18 AWG. The Punch 250, Punch 360,
Punch 500, and Punch 800 utilize heavy duty terminal block connec-
tors that will accept bare wires size from 8-18AWG.
3. REM Terminal – This spade terminal is used to remotely turn-on and
turn-off the amplifier when +12V DC is applied.
4. RCA Input Jacks – The industry standard RCA jack provides an easy
connection for signal level input. They are gold-plated to resist the signal
degradation caused by corrosion.
5. 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 outputs.
6. Gain Control – The input gain control is preset to match the output of
most source units. They can be adjusted to match output levels from a
variety of source units.
7. Punch Bass – The Punch Bass helps correct for acoustical deficiencies
in the listening environment. The Punch Bass allows a narrow band
adjustmentat45Hzto help reproducefullrangesound without excessive
boost. The Punch 120 utilizes a switch that is adjustable at 0dB/+6dB/
+12dB increments. The Punch 160,Punch 250, Punch 360, Punch
500, and Punch 800 utilize a control that is variable from 0dB to
+18dB.
8. InternalCrossover– Theinternal crossover isused to delegatea specific
range of frequencies to the speaker system for optimum performance.
The crossover can perform three functions: High-Pass (HP), Low-Pass
(LP), or Full Range (FULL). The Punch 120 and Punch 160 utilize a
12dB/octave Butterworth crossover fixed at 120Hz HP and 80Hz LP.
The Punch 250, Punch 360, Punch 500, and Punch 800 utilize a
12dB/octave Butterworth crossover variable from 50Hz to 210Hz.
9. LED Power Indicator – The LED illuminates when the unit is turned on.

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 attempt-
ing 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 a fuseholder and appropriate 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 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.

M OUNTING L OCATION
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 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
compartment. Not only will this void your warranty but could create an
embarrassing situation caused by the ridicule from your friends.

B ATTERY AND C HARGING
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.
W IRING THE S YSTEM
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.
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 Power cable for attachment to the amplifier by stripping 1/
2" of insulation from the end of the wire. Insert the bared wire into the B+
terminal and tighten the set screw to secure the cable in place.
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.
Trim the power cable within 18" of the battery and
strip 1/2" of insulation from the end of the wire. Cut
the wire loop that is attached to the fuseholder in
half and splice the fuse into the power line using
appropriate inline connectors. Use the section of
cable that was trimmed earlier and connect it to the
other end of the fuseholder.

3. Strip 1/2" 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 battery
positive terminal. Do not install the fuse at this time.
4. Prepare the Ground cable for attachment to the amplifier by stripping 1/
2" of insulation from the end of the wire. Insert the bared wire into the GND
terminal and tighten the set screw to secure the cable in place. 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
non-anodized screw and a star washer.
5. Prepare the REM turn-on wire for connection to the amplifier by stripping
1/2" of insulation from the wire end. Insert the bared wire into the REM
terminal and tighten the set screw to secure the cable into place. Connect
the other end of the REM wire to a switched 12 volt positive source. The
switched voltage 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.
6. Securely mount the amplifier to the vehicle or amp rack. Be careful not
to mount the amplifier on cardboard or plastic panels. Doing so may
enable the screws to pull out from the panel due to road vibration or
sudden vehicle stops.
7. Connect the source signal to the amplifier by plugging the RCA cables/
high level inputs into the input jacks at the amplifier.
8. Connect the speakers. Strip the speaker wires 1/2" and insert 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.

U SING P ASSIVE C ROSSOVERS
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 (capaci-
tors), 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 Punch ampli-
fiers are not recommended for impedance loads below 2Ωstereo and 4Ω
bridged (mono) loads.
