Summary: I rarely take time to review purchases, but in the case of grossly overstated and misrepresented products - this time was a must. The description says 3100 watts output power, and by most of the other reviews I already expected less. However, it was far worse than I anticipated. A more accurate power rating would be 31 watts. That's right, move the decimal two places to the left. I have a Russound 75 powering the same pair of speakers. I wanted more power.
Very little power: much less than the 3100 advertised.

Summary: I compared this head to head with a 100 watt power amp. Running the 100 watt amp at 75% was far louder than the PQA3100 at 100%. It has nowhere near 3100 watts. It has nowhere near 100 watts. The fan is much too loud for a studio and gets picked up on mics 8 feet away. This amp would be appropriate for a Multimedia system or a home stereo but only if it weren't so loud. As it is, I can't think of a single use for it.
Summary: Shut down within minutes... right out of the box. I was running 2 250w 12s in stereo . Had to crank amp up to even hear anything decent and then it clips and shuts down. Powered of and didn't cycle. Checked it the next day worked fine but again after a few minutes shut down. My crown 600 watt has never had a problem and even my cheap crest amp blows this one away @ 450 w. Maybe I just got a lemon.
Excerpt: PQA 3100 Stereo Amp is a great amp for the price. I use it to power up a 16 channel Tascam mixer with two 12 inch Mitchell monitors, Good clean sound for the money. Sounds good and clean when I use it to play Loud music form my phone or other devices.
Summary: My old Radioahack PA amp rated at 250 watts, blows the doors off this Amp. Not loud, no bass. If I could have rated it lower I woulda. Keep your money. But it was super cheap. Get what you pay for.
