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
