Hey everyone,
I'm new to this forum and to Audis in general and was hoping someone could answer some questions for me regarding a possible sound upgrade to a 1998 Audi A4 2.8 quattro with the bose system. What I was hoping to do was replace the deck (or head unit as I guess it is called) with a Pioneer and then upgrade the speakers and add a 10" sub with amps and capacitors. I had the installers at Best Buy look it over (the existing head unit that is) and after an initial reaction of "I wouldn't mess with it... could mean a ton of damage to the internal computer if you replace it with an aftermarket one" etc., they looked up some information on their computer and eventually were willing to give it a try. I ended up ordering a harness to adapt the smaller pioneer with the larger factory slot and hope to have it installed soon. My concern is about the small screen between the tachometer [sp?] and speedometer. Currently it displays things like the current radio station or cd in the changer with the outside temp and remaining gas miles below. Will removing the factory head unit completely disrupt this screen or will just I still be able to view outside temp and remaining gas miles etc.? Also, there was some worries that in removing the head unit the remote entry or alarm would be messed up. I have seen people with aftermarket decks in their Audis that look pretty slick but there has been no mention of possible complications. On another note, I understand that it would be best to replace any existing bose speakers because they are 1 or 2 ohms and most aftermarket ones are 4 ohms? Can some one explain the difference? I really appreciate any information you can give me. I would really like to incoporate a new, flashier deck with out messing too much of the car up if you know what I mean. Thanks a lot.
