I made a decision on what Ima get. I opted for a DD3512 in a ported box, with a DD 1200W amp and "bass blockers" for the fronts. all this is gonna run me $1300. Im pretty sure this is loud enough for me. BUT, I have the option of upgrading to a DD9512 for $250 more....but the amp will still be a 1200W amp.... worth it? or should I just stick with the 3512?
