input wiring, observe the following:
•
Always use high-quality RCA-type shielded cables.
•
Always use the shortest length possible. If the cable is too
long, make an S-type loop (not a coiled loop) in the center of
the cable to take up any excess.

Never route any amplifier input cables near to, or parallel with,
speaker outputs, high-energy ignition wires, or
computer-controlled ignition circuit units (computer units may

Note
If your car stereo does not have an active +12 volt lead
when it is turned on, you can either install an auxiliary

For floating ground head units, connect the positive (+)
speaker wires only. Do not connect the negative (-) speaker
wires.
For common ground head units, connect both the positive
(+) and negative (-) speaker wires.
Always connect the “signal ground wire” to chassis ground
when using the high-level inputs.
