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
Only one
channel

Weak Output
Noise in the
Audio
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.
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.
Confirm that all speaker strip connections are secure and tight.
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
(switches the R with the L). If the channel which is silent switches to other side,
the problem is either in the head unit/other source or the connecting tables.
Readjust the Input Sensitivity Control to better suit the input signal.
If the noise is a "whine" whose pitch follows the engine speed, confirm that the
amplifier and any other signal sources ( head unit, etc.) are properly grounded.
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 of service.
Check the routing of the speaker and input wires to make sure they are not
adjacent to wires which interconnect lights and other accessories.
Precautions
Before you drill or cut any holes, investigate your car's layout very carefully. Take care
when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring.
Do not operate the amplifier when it is not mounted. Attach all audio system components
securely within the automobile to prevent damage, especially in case of an accident.
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 off while connecting
the input jacks and speaker terminals.
If you need to replace the power fuse, replace it only with a fuse identical to that supplied
with the system. Using a fuse of different type or rating may result in damage to your
system which isn't covered by the manufacturer's warranty.
