Not much is written in the literature. It claims to be a 6 channel amp. There are separate volume controls for the sub, rears, and front speakers. At the back, the same subs (there are 2), rears and fronts speaker connections are present. It claims to deliver 1,400 watts per channel on stereo (which of course is dubios- as in China claims). But having lifted it, I know it is HEAVY- in the vicinity of 20 to 30 lbs. There is a toroidal amp and 4 capacitors rated at 10,000uf each (I peaked the inside).
