For sale is one QSC GX3 power amp. Used but works perfectly. Great for bands or DJs. We used it to power our monitors, while the PA powered the main speakers. But you can use this to power any unpowered speaker you want. Tons of power, 2 channels, great tone. QSC is very respected in the power amp business. $170.00, sorry no trades please.
I've seen this particular model running over $250 for used. I think there's one on ebay right now for $150, but it says it needs repairs.
Here's info from the company:
The QSC GX3 425-watt power amplifier gives your speakers the power they need while giving you the efficiency and protective features you want for easy operation and peace of mind.

It's equipped with a crossover switch, so adding a subwoofer to your system is a snap.
