Problem Cause Action
Unit will not turn on
(no power)
Yellow wire not connected or incorrect voltage
Red wire not connected or incorrect voltage
Check connections for proper
voltage (11~16VDC)
Black wire not connected Check connection to ground
Fuse blown Replace fuse
Unit has power
(but no sound)
Speaker wires not connected Check connections at speakers
One or more speaker wires touching each
other or touching chassis ground
Insulate all bare speaker wires from
each other and chassis ground
Unit blows fuses
Yellow or red wire touching chassis ground Check for pinched wire
Speaker wires touching chassis ground Check for pinched wire
Incorrect fuse rating Use fuse with correct rating
