2. The last lead to be connected is the wire to the positive (+
completed and checked all other connections to the amplifier.
3. By nature of its design, a power amplifier generates heat and requires good air circulation around it to dissipate that
heat. Do not install the amplifier in an enclosed area which does not permit adequate air circulation. Should the
temperature of the unit rise too high, the internal thermal sensors will shut off operation until it has cooled down
sufficiently.
4. If fuse replacement is necessary, use only fuses of the same ampere rating as originally supplied with the unit. The
use of fuses with incorrect ratings may cause serious damage to the amplifier. If fuses blow consistently, carefully
check all electrical connections to the unit.
5. Supply of adequate battery voltage is critical to the proper operation of the power amplifier. The leads to the battery
and chassis ground must be of a thick enough gauge to provide this voltage to the amplifier. We recommend #10
gauge wire or larger (smaller gauge #) for the battery and ground leads.
6. Make certain that the speaker(s) to be used with this amplifier is capable of handling the output power (wattage) of
the unit. Use of a speaker(s) not rated for the output of this amplifier may cause damage to, or failure of, the speaker(s)
for which Audiovox will not be liable.

INSTALLATION DIAGRAM
INSTALLATION INSTRUCTIONS
1. Select a mounting area where the amplifier will
have sufficient air circulation for proper cooling.
Inadequate air circulation will cause the
temperature of the amplifier to rise and will
trigger the thermal protection mode.
2. Place the amplifier on the mounting surface and
mark the locations of the four mounting holes as
shown in the illustration at the right.
3. Remove the amplifier and drill a 1/8" hole at each
of the four locations.
CAUTION: Before drilling the holes, look at the
underside of the mounting surface. Always
check carefully to avoid drilling into wiring,
braces, fuel or brake lines. CHECK BEFORE
YOU DRILL !
4. Apply a self-adhesive rubber washer to the
bottom of the amplifier at each of the 4 screw
locations. Secure the amplifier to the mounting
surface using the self-tapping screws provided.
5. Attach the plastic end panels to the amplifier
by pressing them into position on the amplifier.

WIRING INSTRUCTIONS
Wiring your amplifier will depend on the system and speakers you are using. The amplifier is compatible only with a radio
having a low-level stereo output, thereby instituting a mixed stereo-mono application. The following pages illustrate the
input and output wiring for this type of installation, and any other setup at the user's option. Please refer to the appropriate
diagrams for the system configuration.
The power and speaker wire connections for this amplifier are made via screw tightened terminal blocks. Loosen the
screw for the connection to be made and fully insert the wire (strip 1/2" of insulation from the end) under the respective
screw on the side panel (crimp-on "U" terminals are provided to simplify wiring and we recommend their use). Tighten
the screw down to secure the wire.
1. Power Connection
The battery terminal (+12V) must be connected directly to the positive terminal of the vehicle battery to provide an
adequate voltage source and minimize noise. Connecting the battery terminal lead to any other point (such as the fuse
block) will reduce the power output and may cause noise and distortion. Use only #10 gauge or thicker (smaller gauge
#) wire for this lead and connect it to the terminal of the battery after all other wiring is completed.
2. Ground Connection
The ground terminal (GND) connection is also critical to the correct operation of the amplifier. Use a wire of the same
#10 or thicker) and connect it between the ground terminal (GND) of the amplifier and
gauge as the power connection (#10
a metal part of the vehicle close to the mounting location. This wire should be as short as possible and any paint or
rust at the grounding point should be scraped away to provide a clean metal surface to which the end of the ground
wire can be screwed or bolted.
3. Remote Turn-On Connection
The amplifier is turned on by applying +12 volts to the remote turn-on terminal (REM). The wire lead to this terminal
should be connected to the "Auto-Antenna" lead from the car stereo which will provide the +12 volts only when the car
stereo is turned on. If the car stereo does not provide an Auto-Antenna lead, the remote turn-on lead may be wired
-4-
WIRING INSTRUCTIONS
to an "Accessory" or "Radio" terminal in the car's fuse block. This will turn the amplifier on and off with the ignition key,
regardless of whether the car stereo is on or off. The remote turn-on lead does not carry large currents, so #20 gauge
wire may be used for this application.
4. Speaker Connections
Only 4 Ohm or 2 Ohm impedance speaker(s) can be used with the amplifier. Wire it to the speaker terminals as per
the appropriate wiring diagram. For most applications, #18 gauge wire should be used for the speaker leads but in no
case thinner than #20 gauge. For leads in excess of 10 feet, #16 gauge is recommended. When wiring the speaker,
pay careful attention to the polarity of the terminals on the speaker and make certain they correspond to the polarity
of the corresponding terminals on the amplifier. DO NOT ground either of the speaker leads to the chassis of the vehicle.
5. Input Connections
This amplifier features low-level input and output capability, plus remote sub-woofer level control. The low-level output
capability can be used if an additional amplifier is installed. When low-level outputs are provided from the car stereo,
this amplifier can be included in the audio system as shown in the associated wiring diagram. The amplifier low-level
inputs provide the lowest distortion and best performance. Use good quality shielded audio cables with RCA plugs at
both ends to connect the stereo to the amplifier and keep the cable lengths to a minimum to avoid noise.
If the car stereo does not provide low-level outputs, the amplifier cannot be used, since high level speaker inputs are
not provided.
6. Remote Sub-Woofer Level Control Connection
Remote sub-woofer level control is provided by a PAB-RC control unit, which can be connected to the amplifier using
a REMOTE CONTROL telephone cable (supplied) with RJ-11 connectors at each end. Refer to the amplifier wiring
diagram for details.

OPERATION
After initial set-up, the amplifier should not require any further adjustment unless there is a change in the car stereo or speaker
system with which it is used.

Power Indicator
POWER LED functions as both a power and a
6

warning indicator. When the amplifier is off, the indicator
is inactive and appears white. When power is applied to
the amplifier, the LED indicator illuminates green, provided
no malfunction is present, thus signifying the amplifier is
operating normally. When the LED illuminates red, the
built-in self-protection circuits have been activated and
have shut down operation of the amplifier. The protection
circuits may be triggered by the temperature of the unit
rising above a safe level or by an overload condition. If
activated by a rise in temperature, the unit will resume
operation after cooling off to a normal operating range. If
activated by an overload condition, the source of the
overload must be found and corrected to resume normal
operation of the amplifier. Most overload conditions are

caused by mis-wiring or operation into incorrect speaker
loads. Re-check all wiring and connections if this
situation occurs and correct as necessary.
Level(V) Control
The amplifier is capable of operating from audio signal
sources supplying a wide range of input levels. The
Level (V) control should initially be set to the mid-position.
If it is found that there is not enough output, even when the
volume control on the car stereo is at its maximum setting,
adjust the Level control to increase the output from the
system. If, however, there is still output from the amplifier
when the car stereo volume control is at its minimum
setting, or the output level increases too fast with a small
rotation of the volume control, adjust the Level control to
decrease the output from the system.

Once the correct setting is found, this control should not
require any further adjustment.
Sub-sonic Filter Selector Switch
This switch enables On/Off selection of the sub-sonic
frequency filter, thereby allowing the operator to initially
set the amplifier high pass frequency for a sub-woofer
between 20Hz and 50Hz.
In the "OFF" position of the switch, the response is flat and
unaffected so the entire woofer audio frequency range
(low-pass) is reproduced by the amplifier. Use this setting
if the amplifier is being used to power a full range woofer
speaker.
In the "ON" position, only the frequencies above the
frequency set by the SUB-SONIC FILTER FREQUENCY
(Hz) Control will be amplified and fed to the speakers. Use
this setting to eliminate possible destructive sub-sonic
frequencies (<20Hz). Setting should be at lowest
frequency reproduced by your specific sub-woofer.

Remote Subwoofer Level Control Input
connector permits the amplifier to be used with the

PAB-RC Remote Control Unit. This control unit is
normally mounted in the passenger compartment, and
allows for remote level adjustment of the Bass Boost
audio output from the power amplifier.
Fuse
The circuitry of the amplifier is protected from damage
by automotive-type fast-blow fuses. If fuse replacement
is necessary, use only fuses of the same ampere rating
as originally supplied with the unit. The use of fuses with
incorrect ratings may cause serious damage the amplifier.
If fuses blow consistently, carefully check all electrical
connections to the unit.
Bass Boost Switch
This switch is used to accentuate the bass frequencies by
adding +12 dB of boost to the signal (at 45Hz), or +18
dB of boost (@ 60Hz). Use the +18 dB @ 60Hz for
maximum SPL (Sound Pressure Level).
