• If sound is not output normally, immediately
turn power off and check connections.

• If the fuse blows, check wires for shorts, then
replace the fuse with one of the same rating.
• Check that no unconnected wires or connectors
are touching the car body. Do not remove
caps from unconnected wires or connectors to
prevent short circuits.
• Connect the speaker wires to appropriate
speaker connectors separately. Sharing the
negative wire of the speaker or grounding
speaker wires to the metal body of the car can
cause this unit to fail.
