Need suggestions on a new setup. I'm thinking 2 12" dual 4 ohm type r's in a custom ported box tuned to about 36hz, powered by a Hifonics brutus 1208d wired to 1 ohm. I'll be installing this in a 94 century. I got a 200a alt to put in before hand as well as big 3 in 0/1 gauge and an hc800 if needed can always upgrade if needed. The trunk volume is about 16 cubic feet. As for the cabin area I would say about 40 cubic feet give or take. Overall length is 189", width 70", height 55" if that helps. Any amp/sub suggestions?
