2-12" BL or 1-15" BTL fully loaded?

[slconde 0]

im looking to change my setup. if i go the bl route, my box cuft will be 5-5.4cuft total including port area. if i go btl route, the box will be about the same total. they will be powered by a zx2500 which in the birth certificate says 2700 (if that matters)

now i want to know which will be louder. this will be for daily use in my dodge charger. i currently have 2-15" L7's sealed in a 4.2cuft box and it pounds, but i just want to change it up. plus, i have a feeling that i can get louder than it if i go the FI route. thanx

im also open to other suggestions.

Louder will depend on the install. The BL's have a cone advantage, so that is something to think about.
