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/ |

Gentlemen, All good sound advise ( no Pun intended)
I like the idea of the walkman!!! So on the way home fron eastern washington I stopped at Car toys ( local car audio chain) and picked up a ground loop isolator, $20. it solved my problem..... but I had to craink up the volume to get enough output signal to hear the radio. So... this leads me to the ground loop feedback issue. I went nuts grounding and regrounding all the chasis and connections, it did make a difference, slight buzz instead of huge buzz. I know it is a ground loop problem, I ran out of time but will tackle it a bit tomorrow. I will free wire a ground directly to my battery to see if that leads me in the right direction. I need to go thru all the chasis grounds and remake the connections. If this dosn't work I will take Elliotts advise throw the radio out, and listen to my engine. (IMG:style_emoticons/default/headbang.gif) BTW in my studying I found a very informitave car audio web site, I have to dig up the link and post it later. I'll keep you posted |
