Looking for suggestions on a true clean power amp to run 2 DDAudio 2512 D2's. Had 1 originally running on a DD DM-1000 at 1 Ohm, but amp distorted bad. Hooked it up to the sub side of an Alpine PDX-V9 and even underpowered, it sounded much better. Have two subs now and thinking around 1800-2000 watts at 2 Ohms for an amp. Any insight out there for something that would put that out clean? Any suggestions - greatly appreciated.
