INSTALLATION
Wiring
• Connect the speaker outputs from the head unit to the speakers.
• In some vehicles, it may be possible to utilize the existing speaker wiring. When doing
this, be cautious of the polarity (+/-) of the speaker wires, as these wire colors vary for
each vehicle.
Tip: Using factory wiring harness adapters for the head unit and speakers can help
eliminate wiring issues.
• In some vehicles, it may be necessary to run new speaker wire throughout the vehicle.
Observe caution when routing wires.
• Always use quality connectors that fit tightly, or solder each connection. It may be
necessary to waterproof connections made inside door panels.
• Wiring speakers out-of-phase (the polarity of one speaker is wrong) will cause the
speakers to sound poor, and have very little bass response.
