•
Low or no remote turn-on voltage. Check remote connections at marine amplifier and
source unit.
•
Blown marine amplifier fuse. Replace with new fast-blow fuse (same rating).
•
Power wires not connected. Check battery and ground wiring at marine amplifier; also
check battery connections.
•
Speaker leads shorted. Check speaker continuity to ground, it should not show a
common ground.
•
Speakers not connected or are blown. Check speaker connections at marine amplifier,
measure coil impedance.
•
Thermal protection circuits are shutting marine amplifier off. Check location for adequate
ventilation; consult an authorized Audiopipe Dealer.
•
Gain is not set properly, or damaged speaker cones. Review Setting Gain; inspect
each speaker cone for signs of damage. (i.e. frozen cone, burning smell, etc.)

Marine amplifier is picking up alternator noise or radiated noise. Turn down input gain;
move audio cables away from power wires. Check power and ground connections on
marine amplifier; install an in-line noise filter on source unit's power wire; check
alternator and/or voltage regulator; test for weak battery or add water to battery.
