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. http://www.bcae1.com/ |

Tony,
Does the buzz go up and down in frequency with RPM's? If so an inline filter kit will help a lot. Got one from Radio Shack many years ago and it worked. It has an inline inductor and a capacitor and instructions in how to install. The inductor goes inline on the power lead and the cap goes from one side to ground. You mentioned you got a cap to go inline from RS, but not sure if you got the right stuff. A cap inline will not filter any "noise " out. The people at RS these days don't understand electronics very well from my experience lately. I went in some time ago looking for some diodes and asked the young guy where they had them, he pointed out a cabinet - I went over and it was resistors. LOL!!! Had to look around and find them myself. Tom |

FYI. |
