Good for the price haven't had any problems with it yet so far so good..... 8/26/15 well been using for a little while now and already replaced the speakers with some that can handle the amp sounds better with the new speakers so far speakers have been the only problem.
I was very pleased with my Shark Audio system. It was easy to install and provides great sounds. My only complaint was that the speakers did not come with handlebar clamps. I had to go to Home Depot to buy clamps to mount them on my motorcycle. Other than that, I am completely satisfied.
