Confirm that all terminal strip connections are secure and tight.
Check both in-line and built-in fuses. Both the "+12V" and the
"REMOTE" terminals must have +12V referenced to chassis
ground.
Check the "BALANCE" control on the head unit (or other source)
to verify that it is set to its midpoint.
If you are using the Low Level RCA Inputs, reverse the input plugs
at the amplifier (switch the R with the L). If the channel which is
silent switches to other side, the problem is either in the head
If the noise is a "whine" whose pitch follows the engine speed,
confirm that the amplifier and any other signal sources ( head
If the noise is a "clicking" or "popping" noise whose rate follows
the engine speed, this usually means that the vehicle is equipped
with resistor spark plugs and wires, or that the ignition is in need
Before you drill or cut any holes, investigate your car's layout very carefully.

Do not operate the amplifier when it is not mounted. Attach all audio system
components securely within the automobile to prevent damage, especially
Precautions
Do not mount this amplifier so that the wire connections are unprotected or
in a pinched condition, or likely to be damaged by nearby objects.
Before making or breaking power connections in your system, disconnect
the vehicle battery. Confirm that your head unit or other equipment is turned

Troubleshooting
Before removing your amplifier, refer to the list below and follow the
Suggested procedures. Always test the speakers and their wires first.
No Output
Confirm that the audio signal source (car radio, equalizer, etc.)
is connected and is supplying output signal. To check if the
amplifier is supplying signal, unplug the RCA cables from the
signal source (but leave them plugged into the amp). Gently tap
the center pin of each of the disconnected RCA plugs with your
finger. This should produce a noise (feedback) in your speakers.

Check the routing of the speaker and input wires to make sure
they are not adjacent to wires which interconnect lights and other
accessories.
