symptom

possible cause

distorted output (cont’d)

speakers are blown

poor bass response

speakers wired with wrong

 

polarity causing cancellation

 

at low frequencies

 

crossover set incorrectly

battery fuse blowing

impedance load to amplifier

 

too low

 

short in power wire or incorrect

 

power connections

 

fuse used is smaller than

 

recommended

 

too much current being drawn

 

short in power wire or incorrect

amplifier fuse blowing

too much current being drawn

fuse used is smaller than recommended

action to take

check system with known working speakers and repair or replace as needed

check speaker polarity and repair as needed

reset crossovers referring to the multi-cross™ crossover configuration section of this manual for detailed instructions

check speaker impedance load, if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance

check power and ground connections and repair as needed

replace with proper fuse size

check speaker impedance load, if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance

check power and ground connections and repair as needed

check speaker impedance load, if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance and replace with recommended fuse size

check power and ground connections and repair as needed

replace with proper fuse size
