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.

Try grounding the RCAs.

okay can you explain to me how to do this?

thanks for the reply

Run a wire. Shielding of the RCAs on one end, Ground the other end

I still dont understand that. is there a diagram or a picture i can see to understand. Im having the same issue.

Wrap one end of a bare wire around the metal part of the connectors at the head unit end of the RCA cable. Ground the other end of the wire.

Thanks Im gonna try it.

thanks whtcrxghst,

i got it to work today by grounding the av wire to my ground point.

I guess i must have blown the rca fuse, but its great that i dont have to replace the unit.

thanks for the help

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.
