Symptom
Probable Cause
Poor bass response
Crossover set incorrectly
Impedance load at amplifi er is
too low.
Battery fuse blowing
Short in power wire or incor-
rect wiring.
Fuse used is smaller than rec-
ommended.
Actual current exceeds fuse
rating.
Amplifi er fuse blowing
Fuse used is smaller than rec-
ommended.
Impedance load at amplifi er is
too low.
Speaker is blown with shorted
outputs
Actual current exceeds fuse
rating

Action To Take
Reset crossovers. Refer to the Internal Cross-
over Confi guration section of this manual for
detailed instructions.
Check speaker impedance load if below 2Ω,
rewire speakers to achieve higher impedance
.
Check power wires and ground connections
and repair or replace as needed.
Replace with proper fuse size.
Check speaker impedance load if below 2Ω,
rewire speakers to achieve higher impedance
.
Replace with proper fuse size.
Check speaker impedance load if below 2Ω,
rewire speakers to achieve higher impedance
.
Check system with known working speakers
and fi x or replace as needed.
