I was triing to clean up my center console the other day and moved my booster from inside the console to the outside, passenger side. once I did that I have a very loud and obnoxious buss in my raido. If I plug in and play my I Pod directly into the booster, no noise (IMG:style_emoticons/default/confused24.gif) . I have grounded the raido, booster, even went as far as grounding the sheilds of the RCA cables (and tried different cables) into the booster. That seemed to quiet it up a slight bit but still buzzes when the FM, CD is on.
I then went to raido Shack and picked up a noise supressor (inline capacitor) Still didn't help.
I am begining to think Ignition or Alternator? Every thing was fine till I moved the booster from inside to the outside. This happened once before but not as severe, I just moved a few wires around and it went away.
Any ideas??

Here is the link I found good for the DIY guy who knows enough to be dangerous.

Tony,
If you have a Haynes manual, go to pages 140 and 141. Under paragraph 50, second paragraph down sounds exactly what you are having. It says see figure 10.59, but should be 9.59, top left on page 141. The Bosch alternator has a cap on the rear of the alternator. Because you have a V8, maybe yours doesn't. Pretty easy to check anyway. With alternators, alternating current is being generated and requires diodes in a bridge network to change the AC to DC. There is always some "ripple" or AC component on the DC coming out. Maybe you have some diodes going south and the ripple is getting worse. The amp just amplifies the ripple because it sees it as a signal the same as a signal from the radio or CD player.
