This is a great amp, first one I got didn't work, and they wouldn't just replace it, I had to buy another and return the broken one for a VERY LENGTHY refund. The replacement that I bought does work and works VERY well. Great sound!!

Amp is outstanding. I installed wet sound speakers in back and CICADA speakers in front and the sound is unbelievable. Clear, crisp and bass. Now it turns heads riding down the ride
