Again, it depends upon what you want your system to do. If you want people to hear you coming from down the street, it ain't gonna happen. If you want to be able to roll down the windows and drive 90mph on the freeway and be able to hear your music, you're probably not going to be happy. If you just want to listen to music at a moderate level, you should be satisfied. I certainly wouldn't recommend paying for any kind of factory upgraded audio system. Your $$$ will always go further with aftermarket gear.
