I'm getting alternator whine through my speakers.... do any of you know how to correct this problem>>>????

Year/make/model of the vehicle would be helpful as well as any other aftermarket equipment installed.

ooppss but of course..

2002 Lexus IS300

Aftermarket Amp..

Speaker Set....

i currently have the IPOD cable

6 disc CD changer...

XM Navi Traffic...

and AVic D3

IS the amp powering the interior speakers? If so try changing the ground on that. Make sure the rcas and power are away from each other. The rcas should not run alongside the factory wiring. If he rcas have to cross either factory wire or the power line it should be done at as close to a 90 degree angle as possible.
