Amp will not drive a 1 ohm
mono load, 2 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 8)
Readjust the input level (refer to page 8)
Reconnect power wires properly
Take unit for service
Use good quality shielded RCA cables
Reground amp to clean bare metal chas-
sis
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 prop-
erly
Check speakers
Check crossovers
