Features

Your RadioShack High-Power Stereo Amplifi-

er produces a total of 110 watts to give add-

ed punch and power to your vehicle’s

existing auto sound system.

The amplifier produces up to 55 watts per

channel of clean, powerful sound at all audio

frequencies with minimum distortion. You

can connect your auto sound system’s low-

level or speaker-level outputs to this amplifi-

er.

Its features include:

14K Gold-Plated Noise-Isolated Low-Lev-

el Input Jacks — let you connect low-level

(preamplifier) signal inputs to match your

auto sound system’s output for the best

high-fidelity performance.

14K Gold-Plated Speaker Terminals — de-

signed for low impedance, high conductivity,

and minimum corrosion, to provide the high-

est signal transfer and lowest sound distor-

tion.

Input Level Control — lets you adjust the

level of the audio signals that enter the am-

plifier.

Automatic Power Switching — can auto-

matically turn the amplifier on or off when

you turn your auto sound system on or off

(depending on how you hook up the amplifi-

er).

Mute Turn On Circuit — eliminates the

thump you hear when you turn on some am-

plifiers.

Power Indicator — lights when power is

supplied to the amplifier.

Crossover Frequency Circuit — lets you

adjust the crossover frequency from 45−400

Hz. This lets you set up the amplifier so you

can connect a subwoofer.

Short Circuit Protection — distorts the am-

plifier’s sound if any output channel shorts,

alerting you to turn off the auto sound sys-

tem.

Auto-Off — protects the amplifier by tempo-

rarily shutting down if it gets too hot, an out-

put channel shorts, or it detects an input

overload. The amplifier restarts automatically

when it cools or the problem is corrected.

Protection Indicator — lights if the amplifier

shuts itself down.

THE FCC WANTS YOU TO

KNOW

Your amplifier might cause TV or radio inter-

ference even when it is operating properly.

To determine whether your amplifier is caus-

ing the interference, turn off your amplifier. If

the interference goes away, your amplifier is

causing it. Try to eliminate the interference

by:

• Moving your amplifier away from the

receiver

• Contacting your local RadioShack store

for help

Preparation

SUPPLIED HARDWARE

Your amplifier comes with the following items. Be sure you locate everything listed before you

store or dispose of the packing materials.

BEFORE YOU BEGIN THE

INSTALLATION

Before you install your amplifier, read all the

instructions in this owner’s manual. You

should be able to answer all of these ques-

tions about your vehicle’s electrical and auto

sound systems.

• Does my vehicle have an auto sound

system, such as a car stereo or CD

player, already installed? (You must

have an existing auto sound system to

use this amplifier.)

• How do I connect a wire to the fuse box?

• Which of the auto sound system’s wires

is the power wire?

• Which of the auto sound system’s termi-

nals are low-level outputs and which are

high-level (speaker) outputs?

Also, be aware that installation in your vehi-

cle might require cutting or modifying your

vehicle.

Choosing a Mounting Location

A good location for mounting the amplifier is

in your vehicle’s trunk. Wherever you decide

to mount it, choose a mounting location that:

• does not interfere with the vehicle’s

operation

• lets you drill mounting holes without

damaging other vehicle components

• allows enough space around the cooling

fins for proper airflow and cooling

• lets you easily see the amplifier’s

POWER and PROTECTION indicators

Preparation

Warning: The amplifier gets very hot while it

is on. Do not touch the amplifier or place

flammable objects near it while it is on.

Preparing the Mounting Area

In addition to the supplied hardware, you

need these materials:

• an adapter harness

• additional wire

• shielded audio cables

• 16- or 18-gauge marked or color-coded

wire.

Confirm that the amplifier fits in your vehi-

cle’s available mounting area. This amplifier

requires a 51/2-inch high by 93/4-inch wide by

113/4-inch deep (13.9 ×23.5 × 29.8 cm)

mounting area.

Routing Cables and Wires

Avoid routing the connection cables and any

speaker wires near moving parts or sharp

edges. You can usually route wires and ca-

bles along the wiring channel beneath the

vehicle’s door facings by carefully removing

the molding that holds the carpet in place. Af-

ter routing the cables and wires, replace the

molding.

INSTALLATION ORDER

For trouble-free installation, simply follow the

sections in this owner’s manual in order.

First, make all the connections temporarily

by connecting the amplifier to:

Ground and power

Your auto sound system’s outputs

Your speakers

Then test the connections. When you con-

firm that everything works as expected, dis-

connect the amplifier, mount it in your

vehicle, and reconnect it.

Caution: If you do not make the connections

in the order shown, damage to the amplifier

and your auto sound system is possible if

any wire connections are made incorrectly.

Note: For easier installation, mark each wire

you plan to connect with the name of the ter-

minal you will connect it to.

BEFORE YOU MAKE THE

CONNECTIONS

The supplied connection cables include all

the lead wires you need to connect the am-

plifier to ground, power, and your existing

auto sound system.

Important:

• Do not cut any of the supplied wires. If

you cut any wire, you cannot obtain a

refund or exchange on this product.

However, RadioShack

will

provide war-

ranty service if you cut a wire and find

the product is defective.

• If the connectors on your vehicle’s auto

sound system are not compatible with

the amplifier’s connectors, you might

need an adapter harness to complete

the connections. Your local RadioShack

store has adapter harnesses for most

vehicles.

You might need additional wire, depending

on your individual auto sound system, to

complete the connections. Your local Ra-

dioShack store has a variety of wire and wire

accessories.

6Preparation

Cautions:

• For added safety and to protect your

amplifier and auto sound system, dis-

connect the cable from your vehicle’s

negative (–) battery terminal before you

begin.

• Be sure your speakers can handle as

much as 110 watts of power (55 watts

per channel). Each speaker must have

an impedance of at least 4 ohms. Your

local RadioShack store has a large vari-

ety of speakers.

To make it easier to gauge wire length and

connect the amplifier, temporarily place the

amplifier as close as possible to the selected

mounting location.

CONNECTING GROUND AND SWITCHED/PRIMARY POWER

Follow these steps to connect the amplifier to

ground, switched power, and primary power.

1. If you have not done so already, discon-

nect the cable from your vehicle’s nega-

tive (–) battery terminal.

2. Use a screwdriver to connect the spade

end of the supplied black ground wire to

the amplifier’s GND (ground) terminal.

3. Connect the black ground wire’s other

end to a chassis ground, such as a

metal bolt attached to a metal part of the

vehicle’s frame. Be sure the bolt is not

insulated from the chassis by a plastic

part.

4. Use a screwdriver to connect the spade

end of the supplied blue/white wire to

the amplifier’s REM (remote power) ter-

minal.

If your auto sound system has a

switched power lead

, connect the blue/

white wire’s other end to your auto

sound system’s switched power lead

Preparation

using one of the supplied twist-on termi-

nal connectors.

This connection turns on the amplifier

when you turn on the auto sound sys-

tem, and turns off the amplifier when

you turn off the auto sound system. This

prevents your vehicle’s battery from

being drained if you leave your amplifier

on when you turn your auto sound sys-

tem off.

If your auto sound system does not have

a switched power lead

, connect the

blue/white wire’s other end to a point in

your vehicle’s fuse block that has power

only when you turn on the ignition or turn

the key to ACC.

This connection turns on the amplifier

when you turn on the ignition or turn the

key to ACC, and turns off the amplifier

when you turn off the ignition. This pre-

vents your vehicle’s battery from being

drained if you leave your amplifier on

when you turn off the ignition.

6. Use a screwdriver to connect the spade

end of the supplied red power cable

(with in-line fuse holder) to the ampli-

fier’s + 12V terminal.

7. Connect the other end of the red power

cable to your vehicle’s positive (+) bat-

tery terminal. Then tighten the terminal.

Caution: Due to the amplifier’s high cur-

rent requirement, you

must

connect the

red power cable’s fused end directly to

the vehicle’s positive (+) battery terminal

or damage to your vehicle’s wiring could

result.

Do not reconnect your vehicle’s negative (–)

battery cable yet.

8Connecting Inputs

ˆConnecting Inputs

LOW-LEVEL INPUTS

You can connect your auto sound system’s low-level line out jacks to the amplifier’s low-level

line in jacks.

If your auto sound system does

not

have low-level line out jacks, see “High-Level (Speaker

Wire) Inputs” on Page 9 to connect your amplifier.

Note: For the best results, use shielded audio cables (not supplied) available at your local Ra-

dioShack store.

1. Temporarily place the amplifier as close as possible to the selected mounting location.

If your auto sound system has two line out jacks

, connect the auto sound system to the

amplifier as shown:

Note:

If your auto sound system has four separate line out jacks

, use the auto sound sys-

tem’s front left and right jacks to make this connection.

Connecting Inputs

HIGH-LEVEL (SPEAKER

WIRE) INPUTS

If your auto sound system does not have

low-level line out jacks but has only speaker

outputs, connect your auto sound system’s

speaker outputs to the amplifier’s HIGH IN-

PUT jacks.

• If your auto sound system has four

speaker outputs, see “Four Speaker

Outputs” on Page 10 to connect your

system’s speaker outputs to the ampli-

fier using either a floating or common

ground connection.

• If your auto sound system has two

speaker outputs, see “Two Speaker Out-

puts” on Page 11 to connect your sys-

tem’s speaker outputs to the amplifier

using either a floating or common

ground connection.

Note: A floating ground connection lets the

amplifier provide more power to each speak-

er, but requires that you connect a separate

wire to each speaker terminal. A common

ground connection lets you use fewer wires

to connect the speakers to the amplifier, but

reduces the amount of power supplied to the

speakers from the amplifier.

Use the supplied wire harness and the sup-

plied twist-on terminal connectors to make

the appropriate connections.
