Ground issues after amp install?

So, it all started with the Pioneer AVIC D3 a couple of years ago, now I finally found a good price for someone to throw an amp in for me, out of mere laziness to do it myself. Had a Rockford 4 channel put in to power my 4 Alpine Type-S speakers, and (2) 1 1/2" SPL tweeters. Found the tweeters and front speakers to be blown, then discovered the obnoxious alternator whine now that everything is amplified. Ive had him ground the RCAs on the back of the unit, but it's still there and unless the volume's up, you can hear the whine constantly.
Has anyone encountered this, and if so how did you fix it?
Thanks for the input!
