I Think Im going to go with the 15" BTL, that amp will work for this right. (RF T2000.1) What is the best box I can build. Can some one help me or tell me where I can buy one. I have had a 10W7 with a ported box with a JL 500.1 amp tuned at 35hz and I loved it but sold to a friend. (need something bigger and badder) I used to have to 2 Infinity Kappa perfect 10" DVQ in a sealed box. Like I said I want to be heard, but I do listen to Rock Music also. So throw some recomendations at me.
