Its been a while since I've logged in, and very few things have changed. I did however upgrade from a 12 inch Alpine Type R, to a Type R 15. Man what a huge difference. Same phenomenal quality that has come to be expected from Alpine, but the change in the SPL spectrum is what truthfully shocked me. My 12 would make the dash vibrate but this 15 makes it shake! I bought a rinky Dink box for 20 bucks, while it does do the job, I hate it. Its poorly built. So I come to you guys, can anyone extend a hand and help me with a box design, pictures and 2 or 3D mock ups would be perfect. Here is the goal: I would love to retain modest foot room ( I'm 5'8, wife is like 5'2 hah) And retain modest amount of room to recline. Jump seats have been removed, Jack assembly removed, and the plastics have been cut to make the back wall flat, minus the stupid lip below the window. I'm shooting for roughly 4cu ft, sub would ideally be inverted on top of the box to cancel sub displacement. I would like to try mu hand on a T line design. Whew! That was a lot to type via phone, I'd really appreciate all inputs. additional information: 2001 Ford ranger xlt four door model.
