F150ryder, what is a good sub to go in that enclosure.. ive been thinkin about upgrading to 2 12's... does it beat really hard? ive always been skeptical because its only .73 cu. feet for each of the subs and because you have the seat muffling some of the bass from the sub.. i just have 1 10" mtx thunder 5500 sitting on my backseat and it beats hardd but i need to upgrade now, i got to used to it.. check out the picture in my profile of the setup
