Okay I need help! I have NEVER built an enclosure before, but I am wanting to build one for my (hopefully) new subs, I want the Fi Audio 12 BL's. I am going to run 2 of them in a ported box. I will tune it to around 35Hz and I am going to power the subs with the Sundown Audio SAZ-3000D. My specs are as follows: H, L, D) 16 x 30 x 18. This is going in the back of a 97 Toyota Camry. I don't know which will sound better: subs firing up, port to the rear or subs and port both to the rear. Can someone please help with a design for this thing? Thanks!
