Hey, I need to get some new speakers for my car. I was thinking components. I've heard that the Infinity Kappa's are good speakers. I was looking at the 50.5cs. The ones in there right now are crappy looking 5 1/4. I have some infinity ref 52.5i's in the back for fillers. I wanted to get some good components for the front. I have a roc fos 360 watt amp that I want to hook the back and front speakers to. I appreciate all of your suggestions. Thanks
