Okay...my friends insurance just got him a couple of typr r's 12" and a 1200 watt jbl amp (long story don't ask). However, the shop put them in a crap box. So we were thinking to just make one ourselves. His dad is a carpender so he definatly have all the equipment nessisary to make a nice job. But, i dont have any dimensions or any idea what the box should be ported to. Your input is greatly appreciated.
