Hey guys, first post. I just picked up a 2012 gmc. It needs a system. I want it to out do my four door integra (alpine type s components on Kicker 250.2, DD 1512 in pre fab ported box on 750 watts rms.) I'm thinking two SA 8 v.2, RE XXX6.5 components. I already have the head unit, Sony XAV-63. What do you guys think?
