Currently I got the infinity reference 5x7's (4) in my car. I needed something to replace my stocks and these were cheap. Eventually I will be upgrading them, but I am currently trying to get my amp first which will power what I have nicely, but be enough to eventually power something a bit nicer. Which of the following would you suggest?
1. AXA 440.4
