My stereo system is pretty basic. I haven't gotten around to getting anything like subs or amp yet but eventually I will or when I save enough money. But, my head unit is a Panasonic 50X4 Cd and MP3 Player. I had it in my caddy and put into this car. Also, I got a set of Clarion 6x9's put in on the back deck at First Bass(www.first-bass.com) where I also had my cd player installed.
