Whats up all, got a build im thinking about doing.... 4 15 xl's on 4 aq 2200's in a 87 jeep cherokee, i want to wall it off right behind the front seats. I want it for demo purposes only, playing music. My question to yall is what is the best design to use for best results. Feedback is much appreicated. Clamshell? aeroported? or slot port? Thanks
