Today we'll test out the Quantum Audio QAZ4000D. I recently came across this amp selling for $119 on eBay as a refurbished amp. Ratings suggested 4000 watts at 1 ohm, however with 120A of fusing, it is easy to expect these ratings are inflated. I decided to pick it up anyway so we all can see how the amp performs. Are you ready?
