. . okay, so two times now have i had to replace my deck because the grounding within the deck keeps getting screwed up, at least thats what i beleive it to be. brand new pioneer deck, hasnt been in there but three months, one month it wasnt even used. is there any explanation as to why my car keeps blowing up my decks?. . . the first one i thought may have been due to vibrations from an 8" woofer located under it. so after replacing it i disconected the 8 and had my 12" DMX going for like a week, since that first week it has been all top end playing and then nothing for this last month. so tonight i get all my new stuff (15" DMX 2 new kinetik batteries 2 runs of 0 gauge etc.) and i hook it all up and what do u know my ground loop is back. ran RCAs outside the car, tested powers and regrounded all amps, regrounded front battery, checked all conections, took out the deck and hooked up an ipod thru the RCAs and the loop was gone. . so going to get a new deck tomorow. do i just have bad luck or is there an explanation to my decks getting fried?. . .
