Cure
Check fuses in amplifier.
Be sure remote lead is connected.
Check +12 Volt connection
Check ground connection
Check for speaker short or amplifier overheating
Check power wire or connections
Check connections to radio
Inspect for short circuit or an open connection
Reverse left and right RCA inputs to determine if it
is occurring before the amp
Be sure proper speaker load impedance
recommendations are observed
(If you use an ohm meter to check speaker
resistance, please remember that DC resistance
and AC impedance may not be the same.)
Turn radio volume down
Separate speaker wires and insulate
