I think there should be a filter in the internal or external regulator on your alternator. I could be wrong.

Mine used to do the same thing. every so often it would go to popping so bad i had to turn it off. Over time I replaced alot of factory grounds, with new grounds and cleaned up the rust and road grim from the mating surfaces too. i also upgraded to a bigger internally regulated alternator. The PO had done some shoddy wiring before me. So i removed alot of splices and wiring by replacing whole sections of the chopped up wiring harnesses.

I havent had the problems since.

Also, if you are running an amp, make sure your speaker wires are not close to your amp power wire. i have heard that could cause speaker noise.

cdowns your prob right.
Well so far it seems logical to climb under the dash...again, And check dem grounds.
dznucks...I have a local supplier for alternator goodies. I could build it anyway I need. I'm thinkin good call.
I'm 6'2" (in the morning) and 6'1" at nite.(gravity) So I guess I'll prymyself under the dash later in the day. LOL
Unless someone can give me some "cheat" solution for my slacker mood. Workin man blues you know.
