This amplifier hook up to two kicker 10″ speakers and the power of this amp make the side of my friend Toyota Noah look as if someone is kicking out the side of the van this amp is crazy for what I have seen so far I will like someone else to try it and write a comment on it and I guarantee it will be the same results and for a cheap price it worth it my Rockford 800 watts was thrown in the garbage because of this amplifier
