does anyone know what the big difference between the 2006 models are and the 2004 (or 2005). I'm sort of leaning towards kicker now cuz i can just fit 1 10" kicker sub in my trunk and it'll be as powerful as 2 10's (regular circle subs) ... i was looking at the S10L7 subwoofer ... so anyone who has this sub or knows about it ....ur input is needed

it was my understanding that the L5s put out 600 rms while the L7s put out 750 RMS... this is just what a friend told me, so dont call it fact or anything... i know that im getting a 15" L7... and it sounds heavenly
