I just recently sold my jl audio 12w7 and now i have a 1000/1 that im looking to either hook up to 4 w6v2 10's which would be under powering them a lil i know or a 13 w7. Need some opinions on which would get louder. I know the sound quality will be good on either because of what they are. I have heard the 4 w6's before but never have heard a 13w7. Any opinions?
