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.
