Those logitechs may be high quality, but I can't imagine they'll sound good in the car. The first thought that comes to mind is the woofer. Since it'll be designed for home audio or use in a room it will not have anywhere near the sound quality of a normal car subwoofer. Think about it, it'll be in a trunk dude. Next thoughts and I believe this has been mentioned, but how the heck would you install computer speakers in a car and have them hidden from view. Anyways I'm eager to hear results so if you do it let us know how it turns out for ya.
