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, addi-
tional wire, shielded audio cables, and
16- or 18-gauge marked or color-coded
wires. (Parts and accessories are avail-
able at your local RadioShack store.)
Then confirm that the amplifier fits in
your vehicle’s available 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 cables along the wiring chan-
nel beneath the vehicle’s door facings by
carefully removing the molding that holds
the carpet in place. After routing the ca-
bles and wires, replace the molding.
INSTALLATION
SEQUENCE
For trouble-free installation, simply fol-
low the instructions in the order they ap-
pear 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 expect-
ed, disconnect the amplifier, mount it in
your vehicle, and reconnect it.
Caution: If you do not make the con-
nections in the order shown, or if you
connect any wires incorrectly, your am-
plifier 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. How-
ever, 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 compati-
ble with the amplifier’s connectors,
you might need an adapter harness
to complete the connections. Ra-
dioShack stores sell adapter har-
nesses for most vehicles.
You might need additional wire to com-
plete the connections, depending on
