Unwanted noise is the worst single problem encountered in automotive amplifier
installations. Several basics must be kept in mind when preventing noise
problems.
1. Use shielded cables whenever a preamp level music source is used.
2. All connections must be tight and free from corrosion, paint, etc., and
insulated.
3. Route all signal cables away from existing wiring in the vehicle.
4. If possible, avoid mounting the amplifier in the dash or on the firewall, as noise
may be induced due to the proximity of noisy wiring and switches.
NO SOUND
Check all connections. Check main power fuse. Check accessory fuse. With a
trouble light or meter, be sure +12V is present at the amplifier on the large
positive cable and on the small red/white turn-on wire. Check for a good ground
connection. Check by substitution or other method for proper operation of music
source.
BLOWS FUSES
Check all connections to be sure all power wires and speaker wires do not touch
ground or each other. Re-check polarity of main power wires.
SHUTS OFF
As this amplifier is equipped with a thermal and a short circuit shut-down system,
in the unlikely event of excessive temperatures due to high ambient temperature
or improper speaker impedance, the amp will turn itself off. To avoid damage to
the speakers, turn the volume to a minimum while waiting for the amp to turn
itself back on.
