So i guess i don't have the money to go with my original plan and get 2 12s each with a SAZ-3000 on them so i have a new plan. I wanna compete in SPL and occasionally be able to listen to music and i drive a 03 Tiburon GT. How would 1 18" BTL (fully loaded) with one SAZ-3000 do? (i do have the electrical system to run it) Also if i do this what should my box be? Thanks

Everything you just asked is box dependent. And without knowing how big of a box your car can fit.. no one can help you.

Can you give us the max dimension for the box?

DO you want to see out of the back window or do you want to wall it off?
