Audio Annoyance..., my subs thump when the lights go on Options

AAAAAAAAAAAAARGH!!!!!

my subwoofers thump loudly whenever i step on the break, shift into reverse, open a door or turn on the lights. there is definately a DC pulse going down the audio line somewhere. will a capacitor cure this or is it just a crappy installation (BTW the audio shop that did the install is on my BLACKLIST already)

Audio shop was your first mistake. Capacitor will do little to nothing for THAT problem (IME) Chances are they've given you a ridiculously loud noise'd ground(-) connection. Follow the black wire to where it's mounted onto the chassis, and move it to a clean, unpainted metal surface and bolt it back in.

Also, Where is your AMP located? It may be picking up some kind of frequency from the lights, rare, but is known to happen. Try relocating the amp if all else fails.

NOTE: if you took it to a shop, and you dont know what your doing as far as the wiring goes, then run a search. there are several HOW TO threads. It's pretty easy, G/L!!
