I have been a sound guy for 20+ years and work every day with tour-grade systems ( well sans the pandemic anyway ), but I am always understanding of the need to fit things into a budget. I am lucky enough to work with amplifiers that cost $5,000+ each!!! That being said. If you are on the smallest of budgets, the Behringer NX series is extremely hard to beat. In fact, it performs so well, that it competes with amps that cost significantly more. It is the best budget amp you can get. It has great power density, great features, and performs really well.
I would refrain from wasting your time with any Amazon special or Pyle. The numbers on the box are not even close to true. I have seen MANY of the Pyle units burned up simply because they can't do what the nomenclature states and when asked to try, they just fail after a while.
