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.
Mounting feet
The amplifier is provided with four plastic mounting feet that are to be inserted in the lower slot of the
chassis; please pay attention that right and left feet are different.

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 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.
Only one
channel
Check the "BALANCE" control on the head unit (or other source) to verify that it is set to
works
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.
Weak Output Readjust the Input Sensitivity Control to better suit the input signal.
Noise in the
If the noise is a "whine" whose pitch follows the engine speed, confirm tha t the
Audio
amplifier and any other signal source s ( 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.
