Summary: I would not recommend purchasing this product, I bought this amp June of 2013 and I had this amp professionally installed 6 months ago and it has already stopped working altogether...the lights come on but no sound. One day it worked the next day it didn't.
Summary: Not worth the time or money, worked for a week then started to fall apart. the blue buttons fell off one buy one. Installed in my boat where no moisture could get to it and still had one channel stop working then the next a week or so later. sub channel is all that works now.
