I've been listening to a fine tuned system for so long that I can't handle what's happening to the stock system. I have the stock deck powering some 6"x8" Infinity speakers. At higher volumes the speakers sound like their popping. Now I know this isn't good by why do my Infinity's do this and not my factory speakers that I had? How can I fix it besides the obvious "buy an amp" since my goal here is to turn the car back to stock!
