I have a few of these sub amps. (MCM 30009). Can be modified to run full range with a very simple mod. Think power is in 100+ watt range (will check exact specs in a few days)
H - 9 inches
W - 8 1/4 inches
D - max is 3 7/8 inches
Will post some pics in a few days and still trying to figure out a fair price...
happy new year!
