Symptom Probable Cause Action To Take
Poor bass response
Crossover set incorrectly Reset crossovers. Refer to the Internal Cross-
over Configuration section of this manual for
detailed instructions.
Impedance load at amplifier is
too low.
Check speaker impedance load if below 2Ω,
rewire speakers to achieve higher impedance
.
Battery fuse blowing
Short in power wire or incor-
rect wiring.
Check power wires and ground connections
and repair or replace as needed.
Fuse used is smaller than rec-
ommended.
Replace with proper fuse size.
Actual current exceeds fuse
rating.
Check speaker impedance load if below 2Ω,
rewire speakers to achieve higher impedance
.
Amplifier fuse blowing
Fuse used is smaller than rec-
ommended.
Replace with proper fuse size.
Impedance load at amplifier is
too low.
Check speaker impedance load if below 2Ω,

.
Speaker is blown with shorted
outputs
Check system with known working speakers
and fix or replace as needed.
Actual current exceeds fuse
rating
Check speaker impedance load if below 2Ω,
