January 30, 2012 Best Bang for your buck! Small and Powerful

This amp is the best bang for your buck. It has a lot of power and can easily be bridged and be turned into a 3 channel amp. I have it powering some 6.5 component speakers in my front doors and a JL W3 subwoofer and it does it without a problem. Its tiny and can be mounted pretty much anywhere. I definitely would recommend this to anyone who is looking to buy a 4channel amp.
