Just asking opinions on box design. When I make my boxes for the Hummer which way should I face the subs, and which way should I face the ports for the best output? Subs and ports back, Subs back and ports up, Subs up and ports back, Subs and ports up, Subs angled 45 degrees ETC ETC ETC.

Subs Specs Pages 5 and 6.

I have 50" wide, 42" long and 13" high if I want it flushed. I may go higher than the wheel wells though. Haven't decided yet..





Same year colour and model as mine..

theres no ideal unfortunately, what works in say my car, might sound like crap in yours, and vice versa, thru testing ive learned that my car absolutely hates having, ports up, subs up, or ports/subs forward, has to be ports and subs back angled slightly down for best spl, like i said tho, could be totally different in a hummer, more then likely is,. so yea its basically guess and test

no. box i used to get 147.4 was exactly half of the box in the pic, with 1 12 and 2 ports. you cant have 2 12's in Street A. only 2 10's or 1 12. and i dont have any 10's so i used a 12.

Quick question,

Because the surface area of a single Solobaric 12" L7 is greater than a single 12" round sub would it still be considered Street A class?
