I'm looking to buy a 4 channel amp, and a mono 2000 rms amp. For the 4 channel, I need 50x4 @4, and something efficient. I want it used, but in decent condition. For the mono, I need 2000 rms @1, or something very close to 2k. I would like this to be efficient as possible also. I know what I can buy new and for what prices, so right now I'm looking to see what anybody has used for a good price. My budget for the 4 channel is under $45 shipped, and for the mono is under $275 shipped. Offer up!
