Harness 1:  ADD A SUB

This harness bypasses the need for cutting or splicing by tapping into the speaker outputs of your stock head unit, sending the audio signal directly to your amplifier, powered subs, loc or DSP.  They are colored coded to standard 12V industry colors.

If your amp accepts high level input, then it will most likely have an auto start feature. You will want to confirm by checking the manual included with your amplifier.

NOTE: Subwoofer signal is “mono”, you only need one channel to create your subwoofer signal.

Purple – Right Rear Speaker (+)
Purple with Black Stripe Right – Rear Speaker (-)

This harness is setup to provide a “turn on/turn off” signal wire for amp(s) that do NOT have “auto start”. It also provides constant 12V circuit.

RED = Remote Turn On

YELLOW = 12V Constant. This is used to power your line out converter or DSP. DO NOT ATTEMPT TO POWER YOUR AMP / POWERED SUB WITH THIS WIRE.

NOTE: ALL amps / powered subwoofers will require fused power coming directly from your car battery.
