Thanks,, don't wanna blow the HU,, I may wire it up and just leave rear disconnected since they don't do much in our cars anyways....my brother has no money or car right now and is in debt so he won't be buying an amp, he had one but couldn't get it to work or it was broken,, it helped pay for a dvd player...the box from wal-mart came with cracked plexiglass, good ol' wally world, i may just wait to get pioneer subs,, i think for the money they can't be beat. i know the pioneer door speakers can't be beat for the money
