I was wondering what would be the best kind of box to build to house 2 12's and blow the competition out of the water? I own a 2000 chevy blazerLT and am running 2 Pioneer TS-W301R's in a sealed box (for now) with a Sony Xplod 1200Watt AmpI need to build a better box though for an upcoming comp any ideas to maybe upgrade my current box or to builda better box please let me know. Thanks.

 

Well, you are not going to get real loud with that setup.but get a program like winISD, google it. YOu can play around with the size of the box. usually, a decent sized box ported to around 50hz will get pretty loud, but really depends on your equipment.
