QUICK TROUBLESHOOTING GUIDE
No Power:
Check that all the fuses are good. If so check to be sure that the remote turn on lead is
properly connected, and that both Power and Ground connections are secure.
No Sound:
Check to make sure input cables (RCA) are installed properly. Also, check all speaker
connections both at the amplifier and at the speaker itself.
No Sound / Red LED:
chassis. Be sure the total impedance of the speakers is not too low for the configuration.
Poor Sound Quality (Distortions):
to be turned down (counter clockwise). Check that the speaker wires are not touching the vehicle
chassis. Verify that the vehicle battery is properly charged.
Weak Bass:
One or more speaker connections (+ and -) are reversed or are wired out of phase.
