Fi for my bandpass

[Dodgedzz 0]

I currently have a wall in my car for 6 12s in a bandpass and I'm in the process of upgradeing my subs. My specs on the sealed chambers of my box are 3.69 cubes per side (three chambered box). Just wondering what subs would work best for a daily setup and to compete in bass boxing. Any advice would be helpfull. I'm getting new amps and waiting to get subs before i buy amps

We all do have lifes other than SSA... maybe you should rethink your question and add more information.
