I just know what I read, I have not heard this amp. This amp list Dynamic Power 14.4VDC (2 Ohm Load 140W x 4)(4 Ohm Load 70W x 4)(Bridged 4 Ohm Load 280W x 2). This sounds like it should push small speakers ok. I would not think it would be good as a sub amp. Also I think the price tag is high for what you get.
