So right now I have 2 12" L5's in a Kicker Box. I've heard that if I build a new, custom box then It could be a little louder. I've heard that the subs facing up and the ports facing towards the back would be the best bet. Right now I have the subs facing the back and the port to the side. I've never built a box before so If I could get some help it would be greatly appreciated. Thank You.
p.s - my box right now is 16-3/8"TD x 19-9/16"BD x 32-3/8"W x 16"H and its in the back of a Jeep Commander, so it fits easily and I could use more space if needed.
