PRECAUTIONS
1. Although this unit is designed with built-in self-protection circuits, there may be a possibility of damage if it is not wired
correctly. Please follow the wiring instructions carefully for the type of system being used.
2. The last lead to be connected is the wire to the positive (+) terminal of the battery. Connect this wire only after having
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 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.

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
gauge as the power connection (#10 or thicker) and connect it between the ground terminal (GND) of the amplifier and
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

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
ofthecorrespondingterminalsontheamplifier. DONOTgroundeitherofthespeakerleadstothechassisofthevehicle.
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.

The POWER LED functions as both a power and a
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

This switch is used to accentuate the bass frequencies by
adding +12 dB of boost to the signal (at 45Hz), or +18
