Let me start off by letting you guys know what I have.
1994 Silverado EXT Cab
KDC-322 Head unit, KDC-C719 CD Changer, Alpine 4x6 (Dash), Pioneer 6x9 (rear), MTX Thunderform (under the rear seat).
Now on to my problem, With the engine running, volume down all the way or in between songs there is engine noise making the sub vibrate or flutter. I have gone to www.crutchfield.com and followed all of their online tips for curing engine noise. I have called twice to converse with a tech and no matter what I do, I can't get rid of the noise. I have gone from checking the Antenna to installing and then removing some inline noise filters on the constant and acc wires to the head unit. My next step might be to purchase some Monster brand rca cables and some Mu metal to cover the changer cable (just on the off chance). I have worked on this for several nights with no improvement. I do have to say that this is the first time I have owned a sub and amp. Am I just spinning my wheels, should I let it be? To Me, It seems that there shouldn't be any flutter at all. I would really apreciate it if anyone has any Ideas to help me along on this.
Another issue is, any of you have a changer w/sub set up...if you do, are you able to hear the changer change discs thru the sub? Maybe the 2 problems are connected?
I look forward to your responses.
