I have upfor sale my beloved 5ch memphis belle mch-1300. i really hate to see it go but with my new hru.4 on the way i really have no need for this amp just to run a sub. everything is in fine working order with absolutely no known issues other than the rear x-over switch is partially broken but can still be switched with a small flat head screw driver and works fine. this thing is a beast and can run a system active all day long and still have over 1100 rms watts on tap for the subs. attached is a link with all the specs.
