The only reason this amp is so cheap is because it is used. A little over 3 months old. And the guy im getting it from works in an audio store. And he says that is a good amp. Which i trust him i got my Pionner Speakers in my car from him, and they are really good. Im not sure of the brand of it yet. I am going to look/buy it this weekend. I will post when i get the brand name.
