Hey I've seen this power amps around latley, and they seem to be very nicely priced. Just a few questions. First, are they any good? In the music world, it seems that the more you pay for something, the better quality it is. Do you think this are moderatley priced for a reason? 2nd, they can be used as a bass power amp right? I keep seeing them advertised as DJ power amps, so I wasn't sure. (sorry if that's a stupid question) 3rd, they are advertised as 1000 watts x 2 at 4 ohms. Does that mean it's 1000 watts per side, or both sides equal 1000 watts? (Again, sorry if it's a stupid question) Thanks a lot.
