aiht guys the other day i connected my rear speakrs onto a 200watt amp but now when im driving the car i hear like a "whistling" sound the faster i go the louder the sound gets even if i take away the ground cable from the amp i can still hear it.

So i assume that its coming from bedhing the deck? what should i check? do?

that will work But...


You should try regrounding the radio and the amp first.

Thats "alternator noise" and is usually caused by a bad ground. The isolator really should be a last resort as most whine can be eliminated by providing a better ground.


Make sure its clean. No paint or rust. Also make sure its short. Try not to run the ground more than a few inches.

If that doesn't work get the isolater. and if that still doesn't work, i can send you a link to a more remote possibility. Its really 1 in a million otherwise I'd post it now.
