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
#12 gauge wire or thicker (smaller gauge #) for the battery and ground leads.
6. Make certain that the speaker(s) to be used with this amplifier are capable of handling the output power (wattage)
of the unit. Use of 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
INSTALLATION DIAGRAM
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.
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. Secure the amplifier to the mounting surface
using the self-tapping screws provided.

WIRING INSTRUCTIONS
The wiring of your amplifier will depend on the system and speakers you are using but will either be a stereo, mono, or
mixed-mono application. The following pages illustrate the input and output wiring for both types. Please refer to the
appropriate diagrams for the system configuration you are using.
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) into 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 (BATT) 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 #14 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 (#14 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
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.

WIRING INSTRUCTIONS
4. Speaker Connections
Depending on the type and number of speakers used with the amplifier, wire them 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
speakers, pay careful attention to the polarity of the terminals on the speakers and make certain they correspond
to the polarity of the corresponding terminals on the amplifier. DO NOT ground any speaker leads to the chassis of
the vehicle.
5. Input Connections
This amplifier features both high and low-level input capability. Use either the low-level or high-level inputs, not both.
If low-level outputs are provided from the car stereo, it is recommended that the low-level inputs be used for 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 may be connected via the speaker (high-level)
outputs from the stereo. Wire the speaker leads from the car stereo to the 5-pin adaptor harness as shown in the
diagram (shielded cable is not required for this application) and plug the connector into the mating High-Level Input
socket on the amplifier. Carefully splice and insulate all wire connections.
CAUTION: Use either the low-level or the high-level inputs on the amplifier.
DO NOT use both input levels at the same time.

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.
1 Power Indicator Lamps
The Power Indicator Lamps will light to indicate that
the unit is connected to the battery and that the Remote
Turn-On terminal is receiving +12 volts, thus turning on
the amplifier.
2 Protection Mode LED
This LED illuminates red to indicate that the self-protection
circuits have been activated and have shut off operation
of the amplifier. The protection circuits may be triggered
-10-
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 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.
3 Level (Gain) Control
The amplifier is capable of operating from sources
supplying a wide range of input levels. The Level
control should initially be set to the mid-rotation 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.
4 Stereo/Mono Mode Selector
Set this switch to the Stereo (ST) or Mono (MO) position
as appropriate for the type of system and speaker(s)
you are using.
5 Sub-Woofer Crossover Selector
This switch allows selection of the frequency filters that
permit the amplifier to be used to reproduce the entire
audio range or just the bass range.
In the "FULL" position of the switch, the response is flat
and unaffected so the entire audio frequency range is
reproduced by the amplifier. Use this setting if the
amplifier is being used to power a full range speaker system.
In the "LPF" (Low-Pass Filter) setting, only the bass

8 Cooling Fan
This unit incorporates a fan to provide continuous air
flow through the unit to keep the heat-sink and components
safely within their operating temperature range. The fan
is automatically activated whenever +12 volts is supplied
to the Remote Turn-On terminal.
9 Fuse
The circuitry of the amplifier is protected from damage
by an automotive-type fast-blow fuse. 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.
