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
backwards
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
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
protection
activated
Amplifier driving 2 ohm load or
bridged mono for long
durations
If the amplifier “thermals” frequently while
driving subwoofers, a fan may need to be
installed to keep amp cool
Short circuit
protection
activated
Blown speakers
Check all speakers
Speaker wire(s) shorting to
ground
Check for faulty wiring
Defective crossover
Faulty passive crossover
Low impedance
protection
activated
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
connection to one speaker only
