Hello all need some help please.

I have replaced my door and rear speakers and all is good running from the head unit, think I have the hi to system as have not factor amp in the boot on the left.

I have installed a amp and have wired just the fronts atm but have alternator whine that I can seem to trace. I have tried changing the ground to 3 different places the ground near the battery, battery negative and behind the passenger seat light nothing changed. Unfortunately I have had to use high line converter as I believe there is no pre outs on the stereo.

Lastly I have tried a noise filter but that didn't do anything at all. Any suggestions would be much appreciated.

Thanks in advance
