i own a 2001 chevy impala and right now the stereo is completely stock. i am seriously considering throwing in a computer with a touch screen and this website has been the greatest help so far. before i was thinking that first i'd throw in a new head unit and wire the computer through the rca's on the back. then i realized something. my stock stereo does have an AUX input as do most chevy cars. how would i use this imput with my computer? where could i find an adapter? is it even possible? i dont really want to get an fm transmitter or a new headunit as those would probably cost more. any help or advice you can give would really help.
also would i lose anythign by running my stock head unit through an amp and then to subs and speakers or would i really just be better off buying a new head unit?
