Symptom
Probable Cause
Speaker not connected to amplifier properly.
Internal crossover not set properly for speakers
Speakers are blown
RCA shield connection is intermittent or faulty
Poor bass response
Speakers wired with wrong polarity causing can-
cellation at low frequencies.
Crossover set incorrectly
Impedance load at amplifier is too low.
Battery fuse blowing
Short in power wire or incorrect wiring.
Fuse used is smaller than recommended.
Actual current exceeds fuse rating.
Speaker is blown with shorted outputs
