Troubleshooting

Problem	Possible Cause	Corrective Action
Amplifier does	No power to +12V terminal	Check fuse(s)
not turn on
	No power to REM terminal	Check head unit fuse(s) and wiring
	Blown main fuse at battery	Replace fuse and identify cause of failure
	Blown fuse at amplifier	Replace fuse and identify cause of failure
	Faulty ground	Reground main power ground to bare metal
		chassis
Volume control	Input level control adjusted too	Readjust the input level (refer to page 9)
too sensitive	high
Distorted sound	Input level control adjusted too	Readjust the input level (refer to page 9)
	high
Blows fuse(s) at	Power wires connected	Reconnect power wires properly
amp	backwards
	Internal problem with amp	Take unit for service
Engine noise /	Ground loop(s)	Use good quality shielded RCA cables
Alternator whine
	Faulty ground at amp	Reground amp to clean bare metal chassis
	Faulty ground at head unit	Reground head unit to clean bare metal
		chassis
	Inductive coupling	Reroute RCA and/or speaker wires away from
		factory harnesses
	Input level on amp set too high	Readjust input level (refer to page 9)
Thermal	Amplifier driving 2 ohm load or	If the amplifier “thermals” frequently while
protection	bridged mono for long	driving subwoofers, a fan may need to be
activated	durations	installed to keep amp cool
Short circuit	Blown speakers	Check all speakers
protection
	Speaker wire(s) shorting to	Check for faulty wiring
activated	ground
	Defective crossover	Faulty passive crossover
Low impedance	Amp connected to improper	Check speaker connections
protection	load
activated
	Amp will not drive a 2 ohm	Verify that speakers are connected properly
	mono load, 4 ohm minimum in
	mono configuration
	Speakers defective/blown	Check speakers
	Faulty passive crossovers	Check crossovers
Poor bass	Speakers out of phase	Check speaker polarity; reverse the
response		connection to one speaker only

Note: If the protection light is activated with no speakers connected to the amplifier, and all the power connections are correct, this would indicate an internal problem with the amplifier.
