davej Posted December 18, 2006 Share Posted December 18, 2006 Ran the Eclipse RCAs to the factory amp. Works but I am getting a constant buzz when the unit is powered on. If I bypass the amp and go direct to the speakers, works fine. Any solution for the buzz? Thanks...Dave Quote Link to comment Share on other sites More sharing options...
davej Posted December 19, 2006 Author Share Posted December 19, 2006 I just wanted to post that I figured this out. I added ground loopback isolators to the RCA connection between the headunit and factory amp. FL-GL400 @ circuit city Quote Link to comment Share on other sites More sharing options...

davej Posted December 21, 2006 Author Share Posted December 21, 2006 wait a minute......i have the same exact problem, can u explain what u did more thoughroughly..?? Installing a Eclipse CD4000 unit. I am using the factory speakers and amp. I have a harness from metraonline.com. The harness plugs into the factory harness (that the radio used to) and accepts the RCA inputs from the headunit. Once I plugged the headunit into the RCA of the the harness, everything worked. However, the buzzing started once I powered on the headunit. To troubleshoot, I disconnected the RCAs from the headunit and just ran speaker wire/speaker to one of the speaker wire sets on the headunit. The buzz was gone so I knew the amp caused it. Called Metraonline and inquired and they suggested the RCA groundloop isolators. The isolators get connected inbetween the headunit and the metra harness. This help?

sovietlexus Posted December 25, 2006 Share Posted December 25, 2006 alright, so u ran speaker wires from where the amp is to bypass it all the way to the headunit? Quote Link to comment Share on other sites More sharing options...

davej Posted December 27, 2006 Author Share Posted December 27, 2006 I want you to understand that I AM using the factory amp and speakers. I DID NOT bypass them. Quote Link to comment Share on other sites More sharing options...
