Tebo Posted March 5, 2012 Report Share Posted March 5, 2012 (edited) I had a thread last week about my alternator noise, many people posted with suggestions about to do and ive tried literally everything. Moving grounds, grounding rca's at the headunit, i even spent 30$ on knu shielded rca cables nothing worked. I went as far as buying a new headunit and that didnt help. Its gotten to the point where im figuring it has to be the amp, there are 2 rma's on the back of my aq 4x90 so its had trouble before, i have been battling with this noise for almost 2 weeks and it is insanely frustrating i cant use my new equipment. EDIT: i havet yet to ground the rca's on the new head unit but i really doubt its going to help it wil get done though Edited March 5, 2012 by Tebo Quote 04 dodge dakota ext cab 4x4 excessive amperage 300 amp alt with MONSTER stud =)sundown z v3 15 in a 4th order on aq2200sundown 100.4 2 way active...2 Prv audio 6mb200 & 2 re XXX tweetersdeka intimidatorkenwood x396big 3 1/0 knu wire back to deka intimidator Link to comment Share on other sites More sharing options...
Jaloosk Posted March 5, 2012 Report Share Posted March 5, 2012 (edited) I had a HUGE problem with alternator noise in my car. I fixed it by: 1. running power directly from the battery to the head unit with a floating ground (both + and - were ran to the battery) - this fixed the majority of the issue 2. setting my gains properly - this fixed the rest of the issue Edited March 5, 2012 by Jaloosk Quote "Cheap, good or fast.

Tebo Posted March 5, 2012 Author Report Share Posted March 5, 2012 (edited) Just tried that and nothing! everything i try i get my hopes and it fails again. EDIT: grounded rcas again and nothing. I did notice that when i plug my rcas back into the head unit (only the 4 channel rca) the first one i plug in theres a little pop coming from the speakers and it goes away once the connection is made fuilly Edited March 6, 2012 by Tebo Quote 04 dodge dakota ext cab 4x4 excessive amperage 300 amp alt with MONSTER stud =)sundown z v3 15 in a 4th order on aq2200sundown 100.4 2 way active...2 Prv audio 6mb200 & 2 re XXX tweetersdeka intimidatorkenwood x396big 3 1/0 knu wire back to deka intimidator Link to comment Share on other sites More sharing options...
Jaloosk Posted March 6, 2012 Report Share Posted March 6, 2012 (edited) have you tried changing your source? plug an ipod directly into your highs amp and see if the problem goes away.

Tebo Posted March 6, 2012 Author Report Share Posted March 6, 2012 Tried some more shit today, i ran rca from the amp to 3.5 directly to my ipod no noise. So the noise must be getting from somewhere in the front of the car, near the headunit. I have a buddy that is getting my two rca level ground loop isolators later today Quote 04 dodge dakota ext cab 4x4 excessive amperage 300 amp alt with MONSTER stud =)sundown z v3 15 in a 4th order on aq2200sundown 100.4 2 way active...2 Prv audio 6mb200 & 2 re XXX tweetersdeka intimidatorkenwood x396big 3 1/0 knu wire back to deka intimidator Link to comment Share on other sites More sharing options...

audio1der Posted March 6, 2012 Report Share Posted March 6, 2012 What does it have to do with the DD-1? Are you saying if you turn your gain(s) down, the alt noise goes away? Then do that!
