What size speakers do I have in my 2000 Audi A4 sedan?

I do not have the Bose package, but I do have the "Audi Symphony" receiver. Also, this has the factory Navigation option. Thank you!!!!!What size speakers do I have in my 2000 Audi A4 sedan?Depending on the Symphony package you were given (i.e. the 6 or 8 speaker package), you should have a 5 1/4" set of components (separate tweeter) in the front, and a 5 1/4" full range in the rear deck. If you have rear door speakers (the 8-speaker package), they are 6 1/2" full range speakers.
