8000 watts?? This is one reason why I don't like Pyle. And being the cheapest amp maker on the market, you have to wonder about quality.
Even if that was one channel driven, with a pure square wave output, it's going to make 1000 watts? I find that really hard to believe.
Are there better solutions such as just sticking with a receiver with it's own amps? I have my suspicions that is true, but I have never owned one of their amps.
