im looking to buy a used 12 for my mtx 801d. So the sub has to be 4 ohm dvc i think and 750-850 rms preferred. I'm willing to sacrifice loudness for sound quality and GREAT lows. 75%sq 25%loudness i guess. it must have better sq than assassins! i shall port it. thx tell me what ya got. o yea and my budget is 250 bucks max.
