matt402 Posted May 15, 2009 Report Share Posted May 15, 2009 sure. see what your port area comes out to, make sure u have the room to tune it low enuff, and most importantly at least a double baffle and brace the hell out of it. :hairtrick: Quote Link to comment Share on other sites More sharing options...

cunokyle Posted May 16, 2009 Report Share Posted May 16, 2009 for 16 ft^3 you are going to want at least 190 in^2 of port area. That would be like a 19" x 10" port then with enogh length to get your tuning.

87accord Posted May 16, 2009 Author Report Share Posted May 16, 2009 Yeah I think I will move the bottom sub closer and just do two ports on top and see how much area I have if not I will go with 15" and do one big port behind the driver Quote new system in the works (3) DC lvl 4xls 15's (one of three are here) (2) DD z1 (done) old kenwood four ch 4 runs of 2/0 (done) ? 200 amp alt may two ??
