Hm, thats a good question. i'm not quite sure of the exact specs of this amp cuz there hard to come across. but i do kno it has a switch that says mono or stereo. Theres also a LED light that indicates its doing a 1 ohm load. Also theres a switch on the side that says 1ohm or 2/4 ohms. i looked all over for specs for this amp an i coulden't find them.
