I have a MMATS 3000.05 amp for sale. This thing is a beast, nothing wrong with it just going a different route do to family expansion that is imminent. Cosmetically i would rate it an 8 only cause I'm the 2nd owner of it.... for those of you who dont know, MMATS is made by DD and is 3000wrms @ .5 ohm which means you can run (4) dual 4 ohm subs, (2) dual 2 ohm subs, or (1) dual 1 ohm subs. Has dual 2 guage power and ground inputs.......holla at me
