Jim, I've had this noise in every single aftermarket audio system I have installed in cars when the alternator was working just fine or even brand new! To say that xclusivecar needs to have his alternator checked out because there's a little remaining whine is quite speculative and reaching if you ask me.

xclusivecar, if you're happy with your system, drive the car and crank up the tunes while you're at it. I certainly wouldn't spend any money to have an alternator checked out if your battery isn't weak... alternator noise is typical in high powered head units and amps and I always assume it will be there if I don't use a filter.

Jack, I see what you're saying... so what do the high end amp manufacturers do to eliminate the ever-present alternator whine without filtering that "chokes" down the power?
