ok so how the heck do I know if I have a 'BOSE' system? My 2001 A4 has pretty much near every option, but my factory deck says 'audi symphony', and the speakers do not have a 'BOSE' emblem on them.

So should I assume i DONT have the bose system upgrade?

 

So did you put them in personally or did they pay to have Audi put them in for you?

 

I dont have the emblems on my "concert" sysytem and i had bose. Just open up your door panel and took a look at the speakers themselves, they say bose on em

 

Once I got the speakers, I put them all in myself. The military has its pros and cons, but one big pro is the accessability of a hobby shop.

 

ha figures the lady said i need to pay 40 per speaker. damn

 

If you have a "blown" speaker, first try this:

I pulled apart my door and found I wasn't so lucky and this wasn't the problem, so I called Shokan www.shokan.com, and the next day I had a fully working (used) Bose speaker that was pulled out of a car. Cost $65+shipping
