Clean, powerful sound Don’t have a lot of experience with amps but this comes off as clean, can get loud but even when the volume is turned down the sound quality is higher and more crisp. Definitely powers my speakers well. Recommend.

Such a great amplifier. indont know where to start really, it’s just a fantastic amplifier, easy to use controls are stellar, it’s under rated for sure. The clarity and depth of my speakers is so much better now, even on factory speakers it sounds so much better, truelly a great buy for anyone looking for a serious 4 channel amplifier that’s easy to tune by yourself. The foot print is light and the power is big! Get one!
