I had purchased a new Alpine head unit over a year ago and just finally got around to getting it installed today. I cannot believe how good the stock spearkers sound with the new head, particularly when hooked up to my ipod. Between the new unit and having the car detailed while there it feels like a totally new car. The silver paint looks like it just came off of the show room floor. Probably does not hurt that the car has never been in the rain or parked outside for any period of time.
