PRECAUTIONS
1. Althoughthisunitisdesignedwithbuilt-inself-protectioncircuits,theremaybeapossibilityofdamageifitisnotwired
correctly. Please follow the wiring instructions carefully for the type of system being used.
2. Thelastleadtobeconnectedisthewiretothepositive(+)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
#16 gauge wire or larger (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.

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

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) under the respective screw on the
side panel. 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
adequatevoltagesourceandminimizenoise. Connectingthebatteryterminalleadtoanyotherpoint(suchasthefuseblock)
will reduce the power output and may cause noise and distortion. Use only #16 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
gaugeasthepowerconnection(#16 orthicker)andconnectitbetween 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
toan"Accessory" or "Radio" terminalin the car'sfuse block. Thiswill turn theamplifier onand off withthe 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. 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.

(shieldedcable isnotrequired forthisapplication)and plugtheconnector intothematingHigh-Level Inputconnectors
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.
