Testing

Before you finish the installation, you should perform 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.

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.

Test Speaker Connections

These tests make sure the speakers are connected properly. If speakers don’t play at all, one (or
both) speaker wires may be disconnected.

Troubleshooting

Problem

Possible Cause

Corrective Action

Amplifier does not operate
(power LED not on) when
vehicle and radio are on

No power to +12V terminal

Repair wire or connections

No power to remote wire with
radio on

Check connections to radio with test light

Fuse blown

Check fuse

Volume needs to be turned up
too high for amplifier to work

Input level control too low

Adjust input level control to higher setting

Radio volume is too sensitive

Input level control too high

Adjust input level control to lower setting

Blows fuses

Power wires hooked up
incorrectly

Check power wire connections

Speakers blown or defective

Check speakers

Engine noise (ignition noise/
static or alternator whine)

Improper ground connections;
ground loop(s)

Reroute RCA away from main power wires
Reroute RCA cable
Make sure amplifier is grounded to a clean, solid
part of the chassis/frame

Protect light comes on, and
amplifier shuts down

Amplifier is in thermal
protection

Let amplifier cool down before attempting to turn
back on; some installations may require a fan to
keep the amplifier cool, especially if you are
driving subwoofers with the amplifier

Faulty speaker connection and/
or crossover

Check speakers and/or crossovers for loose or
bad connections

Low battery voltage

Make sure you are getting between 10.8 and
15.6 volts to the amplifier with a digital multimeter
measured at the amplifier

Speaker impedance less than
two ohms

If you are using four ohm speakers, you cannot
have more than two speakers wired in parallel;
amplifier will not operate into two ohms bridged

No output on channels

Speaker wires not connected to
speakers properly

Refer to owner’s manual for proper installation
procedures

Input hooked up incorrectly
