Well I didn't specificaly check it, and this is why: Like I said before, I checked the RCA's and it wasn't them. I did this by popping out my head unit, running a different set of rca's from my head unit to the amp under my seat. Doing this, my RCA's weren't even near my power wire...hmm....another thing i'd like to point out.....my 4 gueage power wire runs along side the drivers side, and then i split off with 8 gage and ran it over to the passanger seat....maybe something went wrong there????
