RidinaZ Posted February 5, 2008 Report Share Posted February 5, 2008 i installed a d3 in my 2003 350z along w/ an amp and front speakers. It was working fine for a couple days until i decided to move the amp. now when the car is on and accelerates it makes a horrible whine noise, very unpleasent. I checked my grounds on the amp( i ended up not moving it and reconnecting all the wires) and it was fine. I get no whine when the d3 is not connected to the amp. any help? im thinking and dreading that i blew the rca fuse but id like to hear input before i contact pioneer.

Empty V Posted February 14, 2008 Report Share Posted February 14, 2008 Wow, a ground loop in a car? That's crazy, I wonder where the source is. He could have also used a ground loop isolator but I'm not sure how much one for 2 RCA's would go for. B-Far Quote Link to post Share on other sites
