HIGH PERFORMANCE STEREO AMPLIFIER

This power amplifier has been designed to provide high quality performance with

a minimum of maintenance. However, it's performance will only be as good as the

care and quality of components with which it is installed. We therefore advise that

you read these instructions very carefully to familiarize yourself with the product and

it's features.

Should you require assistance with the installation or wiring of this unit, please call

our toll-free "HELP" line at 1-800-645-4994 during the days/hours shown.

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

#18 gauge wire or thicker (smaller gauge #) for the battery and ground leads.

6. Make certain that the speakers to be used with this amplifier are capable of handling the output power (wattage)

of the unit. Use of speakers not rated for the output of this amplifier may cause damage to or failure of the

speakers 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 power 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 #18 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 (#18 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.

4. Speaker Connections

Wire the speakers to the "Speaker Output" terminals as per the Output Wiring Diagram (remove 1/4" of insulation

from the end of each wire, depress the spring tab on the connector, insert the wire and release the spring tab). For

most applications, #18 gauge wire should be used for the speaker leads but in no case thinner than #20 gauge. 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 positive (+) 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.

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, these

controls should not require any further adjustment.

3 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.

The Power Indicator LED 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 Level (Gain) Controls

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.
