hmm good to know.. knowing that, i still probably wouldve changed the wires, just because its too much of a pain to try to tie into the wires and re-route them to the amp.. i run 3 pairs of RCA cables from the head unit to behind the drivers seat to the amp.. rather than try to run stock wires to the seat i said just put new ones in

now you have me on pins and needles waiting to see what you are doing with the rears.. i was in a buddys jeep cherokee not too long ago and noticed the stock rear speakers are mounted in the ceiling.. that got me thinking... but not enough to even begin to attempt that sort of project lol
