Solid performer with good power range and very low distortion.
The voltage range is 12v to 25v, but works best at 19v

I am impressed by the power output and the sound quality of such a small board. I played this amp for a few hours and it never busted a sweat. The heat sink just stayed warm to the touch.

Parts Express is awesome! Their customer service is above all else and they will make sure you are always taken care of. This amp is great, puts out ample power and the bridgeable feature is on point. Built in heat sink, direct dc terminals, you can't go wrong here for the price and the power.

Has no trouble driving a pair of 6.5" coax speakers in a DIY boom box. Puts out great sound, and decent quality bass. I'm feeding 12v into it, and the speakers are rated at 4ohms.
