Symptom Probable Cause Action To Take
Speaker not connected to amplifier properly. Check speaker wires and repair or replace as needed. Refer to the Speaker Con-

Internal crossover not set properly for speakers Readjust crossovers. Refer to the Internal Crossover Configurations section of
this manual for detailed instructions.
Speakers are blown Check system with known working speakers and fix or replace as needed.
RCA shield connection is intermittent or faulty Replace/Repair RCA cable
Poor bass response
Speakers wired with wrong polarity causing
cancellation at low frequencies.
Check speaker polarity and fix as needed.
Crossover set incorrectly Reset crossovers. Refer to the Internal Crossover Configuration section of this
manual for detailed instructions.
Impedance load at amplifier is too low. Check speaker impedance load if below 1Ω, rewire speakers to achieve higher
impedance .
Battery fuse blowing
Short in power wire or incorrect wiring. Check power wires and ground connections and repair or replace as needed.
Fuse used is smaller than recommended. Replace with proper fuse size.
Actual current exceeds fuse rating. Check speaker impedance load if below 1Ω, rewire speakers to achieve higher
impedance .
Speaker is blown with shorted outputs Check system with known working speakers and fix or replace as needed.
