Vr Commodore alternator whine

Hey guys I've just installed a 4 channel amp to run my speakers however after trying a few different ground points and methods I can not rid this annoying noise PLEASE HELP!

Have you tried taking out the 12V wire? and checking if the sound still exists, Might be shorting out your alternator?
