I just got my 2001 A4 and i was lookin at replacin all the speakers, however, every site I go to doesnt list what size speakers the car has in the front and rear...most places say "rear speakers not available" "front speakers not available" so basically what im wondering is what size speakers are where on this car if you guys could help me out it would be great.

 

OK< I was waiting for someone else to respond, but go to cartoys.com and use their configurator. I don't think it's dead on on the R deck woofs, but everywhere else I bet it's ok...

 

If it's a B5, your stock fronts are 4" components but with an A4 speaker adapter you can fit 5.25" components. The stock rear are a 6.5" coaxial, with a speaker adapter your can fit aftermarker 6.5" coaxials.

If it's a B6 or has Bose, I don't know.
