If its coming through the speakers, could it be related to alternator?
I'm assuming you've turned the radio off to see if the noise is still there?
Is it a high pitched sound or just a buzzing whinning sounds?

doesn't exist when stereo is off isn't related to the stereo volume and changes pitch with engine revs

Its a little box that bolts to the alternator and shuts up the whining, should pick one up at the autofactors for not much less than a tenner
or the inline type

Test it with a multimeter, testing the output to see if its higher than normal (should be around 14v if I recall) if it is - overcharging might cause this issue.

damn! I know what is causing this now... the only change I made that could cause this is the second amp so yes I had to route the power cables under the pass side plastic sill cover. I think the second amp is causing flux interferance.
Cheers gaz... will reroute the power cables this weekend...ish
