Default Re: Sub plays while stereo is off

Even when you turn off the radio the tube keeps playing. I used the FAST-9999 with the FAST-BTAH wire harnesses to conect it.

FAST - Radio
Red - Org/Blk
Blu/Wht - Yellow
White - Wht/Blk
Wht/Blk - Gry/Blk
Gry - Wht/Red
Gry/Blk - Gry/Red

I grounded the harness to a seat mounting bolt.

Any help would be great. Thanks.
Relocate your ground wire to see if this eliminates the problem. Also check to make sure all of the connections at the headunit are secure as well as the harness at the FAST-9999 and the Tube. If this all checks out, locate another constant +12v power source.
