Test Power Wiring

1. Turn on the receiver but do not turn up

the volume. The amplifier power light

should come on. If not, check the

REM and +12V wires.

2. Turn up the receiver volume slightly. All

speakers should operate. If not, check

wiring connections at amplifier and

speakers.

Testing

Test Speaker Connections

These tests make sure the speakers are

connected right. If speakers don’t play at all,

one (or both) speaker wires may be

disconnected. If the wrong speaker plays (you

hear left speaker when you expect right

speaker) make sure you connected the wires

correctly.

Before you finish the installation, you should do the following tests to make sure the wiring is correct

and everything is operating properly.

Reconnect Battery

When wiring is complete,

reconnect the battery

negative terminal.

Bass

Level

The input level control matches the output of

your radio to the input of the amplifier. After

the installation is complete, make sure the

input level control on the amp is turned down

all the way (counterclockwise or all the way to

the left). Play a tape or CD (make sure bass

and treble settings or EQ are flat too) and

turn the volume up slowly until you just start

to hear distortion. Now back the volume down

just a bit. On the amp, slowly turn up the input

level control (clockwise or to the right) until

you just start to hear distortion and back it

down a bit. Now your radio and amplifier

levels are matched.
