Features

Your RadioShack High-Power 2/1 Chan­nel Bridgeable Amplifier produces a total
of 200 watts to give added punch and
power to your vehicle’s existing auto
sound system.

The amplifier produces up to 100 watts
per channel (if bridged) of cl ean, 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 amplifier.

Its features include:

14K Gold-Plated Noise-Isolated Low­Level 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

— provide low impedance, high conduc­tivity, and minimum corrosion for the
highest signal transfer and lowest sound
distortion.

Mute Turn-On Circuit — eliminates the
thump you hear when you turn on so me
amplifiers.

Power Indicator — lights when power
is supplied to the amplifier.

Protection Indicator — lights if the am­plifier shuts itself down.

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
amplifier’s sound if any output channel
shorts, alerting you to turn off the auto
sound system.

Auto-Off — protects the amplifier by
temporarily shutting down if it gets too
hot or it detects an input overload. The
amplifier restarts automatically when it
cools or the problem is corrected.

Input Level Controls — let you adjust
the level of the audio signals that enter
the amplifier.

Automatic Power Switching — can
automatically turn the amplifie r on or off
when you turn your auto sound system
on or off (depending on how you hook
up the amplifier).

Bridging Capability — lets you com­bine the amplifier’s two 100-watt chan­nels so you can use the amplifier with
only one channel that produces a total of
200 watts.

Preparation

Your amplifier comes with the following items. Be sure you locate everything shown
before you store or dispose of the packing materials.

FUSE 30A

Red Power Wire (1)

Black Ground Wire (1)

Blue/White Remote Wire (1)

4-Pin Connector with Wire (1)

Sheet Metal Screws (4)

BEFORE YOU BEGIN THE
INSTALLATION

Before you install your amplifier, you
should be able to answer all of these
questions 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
terminals are low-level outputs and
which are high-level (speaker) out­puts?

Flat Washers (4)

Lock Washers (4)

Also, be aware that installation in your
vehicle might require cutting or modify­ing your vehicle.

Connectors (5)

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

Before you mount the amplifier, make
sure you have all the materials you
need, such as an adapter harness, a dd i­tional wire, shielded audio cables, and
16- or 18-gauge marked or color-coded
wires. (Parts and accessories are avail­able at your local RadioShack store.)

Then confirm that the amplifier fits in
your vehicle’s available mounting area.
This amplifier requires a 3

by 10
(8.5 × 26.5 × 36.1 cm) mounting area
with adequate ventilation space.

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 cables along the wiring chan­nel beneath the vehicle’s door facings by
carefully removing the molding that holds
the carpet in place. After rou ting the ca­bles and wires, replace the molding.

INSTALLATION
SEQUENCE

For trouble-free installation, simply fol­low the instructions in the order they ap­pear in this Owner’s Manual.

First make all the connections by tempo ­rarily connecting the amplifier to:

1. Ground and power

2. Your auto sound system’s outputs

3. Your speakers

Then test the connections. When you
verify that everything works as expect­ed, disconnect the amplifier, mount it in
your vehicle, and reconnect it.

Caution: If you do not make the con­nections in the order shown, or if you
connect any wires incorrectly, your am­plifier or your auto sound system could
be damaged.

Note: For easier installation, mark each
wire you plan to connect with the name
of the terminal you will connect it to.

BEFORE YOU MAKE THE
CONNECTIONS

The supplied connection cables include
all the lead wires you need to connect
the amplifier to ground, power, and your
existing auto sound system.

Important:

• Do not cut these wires. If you cut

any wire, you cannot obtain a refund
or exchange on this product. How­ever, RadioShack will provide war­ranty 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. Ra­dioShack stores sell adapter har­nesses for most vehicles.

You might need additional wire to com­plete the connections, depending on

your individual auto sound system. Your
local RadioShack store carries a full line
of wire and wire management accesso­ries.

Cautions:

• For added safety and to protect your
amplifier and auto sound system,
disconnect the cable from your vehi­cle’s negative (–) battery terminal
before you begin.

• Be sure your speakers can handle
as much as 200 watts of power (100
watts per channel if you connect

SWITCHED/PRIMARY POWER

your auto sound system to one pair
of speakers, or 200 watts per chan­nel if you connect your auto sound
system to a subwoofer and bridge
the amplifier’s outputs). Each
speaker must have an impedance of
at least 4 ohms. Your local Ra­dioShack store carries a full line 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.
