Hi, I have a pair of inifinity kappa 62.5 i 6.5" speakers i am going to put in the rear of my car and then am getting infinity 60.9cs components for the front. I also have a alpine 9886 on the way. i was just wondering what kind of 4 channel amp would be a good fit for these? I am trying not to spend more then $250 on the amp. I was looking a this: http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=17033 but read some mixed reviews on it that made me kind of paranoid. Could you guys recommend me a amp? thanks
