Hey I just sold my last system a SI Mag 15 running off a ED Nine.1. This time around i'm looking for all out spl. I narrowed the choices down to a 18" TC5200, 18" FI BTL fully loaded, and a DD9515 (do they come in 18's?). What do you think will be all out loudest out of the choices? The amps I narrowed it down to were the IA 40.1, Memphis 4kw, Adassa Audio Warlord which one would put out the most power at 14.4v's ? I'm looking for daily driver loud the box is gonna be 6.5 cubes tuned to 30-32hrtz. Also do you think 2 12's off the same amp would be louder then the one 18" with the same power?
