I hate to do this, but the idea just isnt working for me. I have 2 powerbase xtreme 12s dual 1 for sale, they are brand new never seen power nor mounted, I took them out the box cause I have no room to store boxes so shoot me some offers. Im lookin for somthing Louder, but cash would be fine, I will be using a pair of orion 250g4s for the upcoming season, I guess I will need a total of 4 d2 subs either 12,15,18 looking to have the rms from 500-800.
