scotspitch56 Posted April 3, 2009 Report Share Posted April 3, 2009 i finally installed my 2 4 channel last night and component install. after this was done there was a really loud 'whining' noise. (like what usually occurs when rca's are too close to power) so i checked all wiring and it all seems correct. i tried ground loop isolators on the fronts/rears/sub rca's and still no luck. i had one guy on usaci forum tell me that he's an authorized dealer and said that pioneers are infamous for causing this problem. anyone else ever have this issue? if so how did you fix it? its an avic d3- only had 1.5 years if that. the other issue is that if my rca's for my subs are unhooked i get less music out of components. but if i plug in just 1 of the subwoofer rca's it gets louder.... anyone else think this is odd??
