BOOM: these subs ( JL Audio 12 W7's) are supposed to be the best out there. I have 2 Phoenix Gold amps running and a line-driver going as well. It hit around 152 db's at the last contest and they won't turn all the way up because they suck the life out of the battery! The line-driver should help to give them more power b/c I have the best PG Tantrum I could find in it!
