Hey so like every1 i wanna totally redo my whole system, Right now i have CDT Hd's with about 100 watts going to them very underpowered and A Brahma 15 ported to about 32 Hz 3 Cuft With a viper 1200.1 on that. I wanna go Louder. I was thinking maybe 2 12's or 2 15's Sx's with 2 viper 1200.1's. Either Sx's or Maybe like 2 12 inch XXX's But with the givin power I fiqured the Sx's will be more then enough no? Also i wanna get a better amp for My Comps maybe even upgrade to the New O7's from CDT. Can any1 help me out with opinions or if they have maybe heard 2 Sx's. And will there be a huge diffrence between 2 12's and 2 15's if i have the same 1200 watts going to them.
