Hey guys...wonderin if this has happened to anyone else, or if u know whats wrong.

While driving I can notice that my cluster lights and the other various interior lights actually dim for about 20 secs or so, and then go back to normal brightness...the dimming isnt really bad, but just enough so you notice it. Guess im wonderin what could cause it? :)

bump? :) :)

Do you have a system? And if yes, does the dimming happen when you hit a low tone?

Well i have a sub...but thats it, and its only a 10 so doesnt draw that much power. Plus I have an optima battery and its in the trunk. But in answer to ur question, no it doesnt dim durin that :)

Maybe you're alternator is goin bad
