I’m a music fanatic I’ve dealt with hundreds of amplifiers but I must say that I’m impressed with the simplicity and sound quality of this amp’s built in crossover system and also the power of the final stage.I used it for midrange and this amp thumped my home made 800 watts compression drivers to the limit for half an hour without even breaking a sweat,lol,it put my other amp{2500 watts}in the dark which overheated and shut itself off after playing the same drivers for about 12 mins.SO overall great price very powerful definitely will buy this amplifier again.
