• When routing RCA cables, keep them away from the power cables and output
speaker wires, engine, exhaust system, etc. Heat may damage wires.
• If the fuse should blow, make sure that all connections are correct, the cables have
not caused a short circuit, and no wires are damaged. Then replace the fuse with a
new fuse of the same amperage value as the original fuse. When replacing a fuse,
never let the battery side touch any metal part or any other wire.
• Never let disconnected cables or terminals touch metal on the car or any other
conducting material.
• To prevent short circuits, do not remove the caps from unused terminals or from the
