My 10 in subwoofer in my srt 4 neon doesnt seem to work need help

do u have sound but no light?

I ran my neon straight from the power from the amp so soon as accessories comes on they light up!

Run neon wires positive to the amp directly p.con & negative to negative on ur sub outlet!

Mine had the same prob & it was trial & error & that set up works for me & a few mates have done the same!
