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
