aja656 Posted May 4, 2007 Report Share Posted May 4, 2007 does your D3 make a high pitch squeal for 2-3 seconds after you turn your car off? does anyone know what this could be? it only happens when i have the RCA shields grounded to prevent speaker whine. thanks Quote Link to post Share on other sites
MisFit Posted May 4, 2007 Report Share Posted May 4, 2007 why dont you try an inline noise filter rather than grounding your rca's. or run a ground reference wire from your amp to your head Quote Link to post Share on other sites
cntrylvr79 Posted May 4, 2007 Report Share Posted May 4, 2007 why would you ground an amp to a person's head? Doesn't sound like it would work too well. Then you have the pain involved in drilling a screw into his head. Hmmm is that how they do things up there? Quote Link to post Share on other sites
aja656 Posted May 5, 2007 Author Report Share Posted May 5, 2007 what is a ground reference wire from your amp to your head please explain Quote Link to post Share on other sites
MisFit Posted May 5, 2007 Report Share Posted May 5, 2007 what is a ground reference wire from your amp to your head please explain run a wire from your radio ground wire, and connect it to the amp ground wire. this sometimes helps with amp noises or try an inline rca noise fillter as mentioned above Quote Link to post Share on other sites
