How do i start? Well,i have already installed a pioneer deck,am/fm/cd,I decided to upgrade to a avhp-4900 am/fm/cd/dvd/flipout screen.Ive tried 3 different units all having the same issue.With the volume turned all the way down,right from the start there is a horrific noise.The first deck i had no problems with whatsoever,NONE! But as soon as i go to install the new dvd deck(s) there is this big issue.Ive tried running a new ground,new rca"s, bypassing the factory harness(my own power,ground,constant)I tested the speakers by disconnecting the leads from the amp,then hooking the leads to a 9-volt battery to double check proper connection and to check for the speakers grounding out somewhere.Ive never encountered these issues before,its very stressful indeed!! I tried running the ground from the deck straight to the same ground as the two amps and the crossover are,still,no help.The last thing im going to try is to hook up the door and rear panel speakers together without using the harness,can ANYONE help me or have any ideas??Any help would be grateful!! I love my magnum,but i need music and would love video as well.Thanks very much!!!!!
