Any suggestions on how to eliminate the high-pitched whine? The whine's there even when the radio's off, as there is no remote off connection off the head unit, apparently.

PS - Nice installs on your Gallery page!

did you get this installed at a shop? they should be helping you with most of this, but here are some ideas.

first thing I would do is pull the RCAs out of the amplifier, does the whine still exist? This makes sure the problem is at the amp end and not the receiver.

dumb question, but which side did the installer run the rca preamp cables? i'm pretty sure there is a car powerline running on the drivers side.

did they have to run power to the HU? (only certain HUs required this)

next double check the ground point for the amp. i would use a point that is not used by another electrical device ( like the tail-lights etc) where did they ground the receiver? make sure there isn't a ground loop!!


how loud is the whine?
can you hear it idle or only under power?
have you shifted where the amp sits in the boot? I know that amp is kinda large, but I've found the drivers side of the boot to be "quieter" then the passengers side (well for my amp at least).


i recently went through this, so it's best to go in with a plan. i found that raising the amp (in height) did little good. I still have a slight whine at around 3000 rpm, but i'm still working that out (as is the case with all things car stereo!)
