I have 2 12" pioneer premier TS-W3001D4 champion pro series subs. There 3000W Max and 1000W RMS each. There in a 15"x15"x45" custom built MDF (high density fiber board) box with 1.5" ports on both sides for each sub.(Just never carpeted- thats $20). I bought them about a year ago and they were in my car until it died. I bought them brand new, broke them in and all, werent even used a lot because i was away at college 8 months the year. There each 4-ohm dual voice coil, great subs. Lookin for $350 OBO for it all. Will also sell the subs alone 130 each/ 225-pair firm. The subs are already wired also with a couple feet that come out of the box. Thanks, 413 563-2155
