Right now all i have enough room for is a either 2 12s in a ported box at 4.2 cubes, which is my current set up with two SA-12s and probably getting a Rockford Fosgate 2500. or would a single 18" with a 2500, i would probably go with a Fi Q, in a sealed box because i dont think there will be enough room for a ported 18".
What would get louder?
