[QUOTE="MitchZ, post: 4331262, member: 578653"] I read the tutorial stickied at the top of this page, but I just got a new car, came with a Kenwood deck. I don't remember the model but it has the 4.0 v outputs. The engine whine is minor. I haven't regrounded the deck yet. I'm assuming that I need to ground the RCA's; but the RCA's are exterior from the deck. They come out of the deck from a cord which is about 6 inches long and it plugs in there. How can I ground this? Oh.. I forgot to mention. The car is a 1995 Mustang with a Stock Mach 460 sound system. (So theres a exterior stock amplifier) This was all installed from when I got the car. There was no engine whine with the setup that it came with. (Aftermarket deck + stock speaker amp) I put my speaker amp in. (MA Audio 100RMS x 4) and bam! Engine whine. I think its the ground?
