Low or no remote turn-on voltage: check remote connections at the amplifier and source unit.

Blown amplifier fuse: replace with a new fast-blow fuse (same rating).

Power wires not connected: check battery and ground wiring at the amplifier and check the battery connections.

Speaker leads shorted: check speaker continuity to ground; it should not show a common ground.

Speakers not connected or are blown: check speaker connections at the ampli- fier and measure at speakers. Measure coil impedance at amplifier with speaker wires disconnected.
