update on alternator noise over speakers

[Griffon Financial]

Hi all,
I first of all want to thank all of you who replied to my first post.....
After doing some rewirng and taking the advise of the majority of you whom
said it was a bad ground, I have still not gotten rid of this damn
noise....here's what I have done....I reground the head unit to the body of
the car,  reground both of my amplifiers to the body using those star
washers that dig into the metal. I have rerouted the 12v power from the
battery so it does not run parallel with the RCA cables.
    The remote/ ant lead(from the headunit)  which triggers the amps still
run's parallel to the RCA's however, could this be the culprit???  One
wouldn't think so, there isn't much voltage going through that wire.  At any
rate I need to somehow narrow this little shit down, Is this whine caused
from my head unit not having a good enough ground or is it the amp grounds.
Any help is appreciated!!!


Thanks
