Just enough power to push my 3 way speaker which have 2 15's in each tower, 4 15's total

So the tuner has a weak outdated design and the difference can be clearly heard when using a digital input.3: System seems to have enough power to power all the speakers just on one zone

The figure of 3000 W is truly doubtful but still has enough power to get the job done

I am very pleased with my purchase, the amp has adequate power mounts nicely and has good sound if you are not pushing it to its limits

Has more then enough power to supply my 15" DJ speakers

I also wonder if i can hook up another just like it to give me just a bit more power

it has its problems, but getting the power i do for about 120$ is not bad at all.(atm 2 probs, some times my amp wont properly push 2 ohms, turning it off and on a few times seems to fix it, also the fan needs lubricant in it, it grinds fairly loud when cold.

I thought it was a great deal being a two for one, Amplifier and Receiver both in and out work great with nice power
