Troubleshooting
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.
Problem Possible Cause Corrective Action
Amplifier does
not turn on No power to +12V terminal Check fuse(s)
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
too sensitive Input level control adjusted too
high Readjust the input level (refer to page 9)
Distorted sound Input level control adjusted too
high Readjust the input level (refer to page 9)
Blows fuse(s) at
amp Power wires connected back-
wards Reconnect power wires properly
Internal problem with amp Take unit for service
Engine noise /
Alternator whine Ground loop(s) Use good quality shielded RCA cables
Faulty ground at amp Reground amp to clean bare metal chassis
Faulty ground at head unit Reground head unit to clean bare metal chas-
sis
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 protec-
tion activated Amplifier driving 2 ohm load or
bridged mono for long dura-
tions If the amplifier “thermals” frequently while driv-
ing subwoofers, a fan may need to be installed
to keep amp cool
Short circuit pro-
tection activated Blown speakers Check all speakers
Speaker wire(s) shorting to
ground Check for faulty wiring
Defective crossover Faulty passive crossover
Low impedance
protection acti-
vated Amp connected to improper
load Check speaker connections
Amp will not drive a 2 ohm
mono load, 4 ohm minimum in
mono configuration Verify that speakers are connected properly
Speakers defective/blown Check speakers
Faulty passive crossovers Check crossovers
Poor bass
response Speakers out of phase Check speaker polarity; reverse the connec-
tion to one speaker only
