Phoenix Gold Phorum

Hi everyone I recently purchased a used tbat and finally finished my install. The problem I am having with the unit its producing a bad fuzz and crackling noise when I turn my amp (zpa 0.3 )gains to the lowest position, as well as when I use my power windows I hear a pop throug my speakers. To save time I just switched my tbat for the second one I have and the problem is eliminated, my question is anyone know if it is fixable I am assuming it is a ground problem but who knows, oh well thats what happens when you buy second hand ..but I hope I can get it fixed....any advice would be great ..thanks in advance

I would imagine anything is fixable....maybe you can take it apart and snap some pictures for Eric D or 1moreamp or maybe some of the other more technically inclined guru's to help you disect your problem.
