I have to admit that i was afrait of that im going to buy an other cheap amplifier with overestimated and overrated capabilities. Now i have been using this amp for months and i have to tell that im not too gentle to it. Im driving 2x2000W rms double 18" bass bin each side (4 ohms) or 2x double 15" 1000w x2 each side (2 ohms) I was like if it fails i will live with the warranty, but it never lets me down. Even on 2 ohms, the performance wouldnt drop, and wouldnt overheat. Yes, it is a very heavy amp to carry around, but if you want serious power to come out of it, you have to deal with!!!
