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