I'm in total agreement with the first post. The only difference with my system is that it is just the singal disc not the CD Changer.
I just installed 2 10" sony subs and 480 watt Xplode amp and it brings the system to life. The stock system has decent highs and mids, but no lows. An aftermarket sub/amp combo was the fix. I'm so glad I went this route. See my thread for pics:

It was installed by Circuit City. They did have to talk to JBL because they were unsure of how to wire up the AMP. My AMP has Line Speaker inputs so they didn't know what speaker to tap into. Don't ask me what they did as I am not a qualified installer. you might have to just call JBL like they did to figure it out.
