I want to put in new speakers in my front doors. I know that I have 4's and 1'' tweets but is it possible to put in 6 1/2 without changing the door panels.

thanks

I have a '00 A4 and I emailed Crutchfield on what would fit and this is what they emailed me back.
I have the speakers & accessories that I recommend loaded on a cart for you. We send a bracket for free with your speaker purchase that allows a 6-1/2 after market speaker to mount in the back window/rear deck. You will need a baffle to get a good seal around the speaker, I also added some bass blockers for the small speakers that are going up front. This will keep them from distorting every time a deep bass note drops.

Do you know how to install a new cd player deck?

Clearance behind the speaker is a big issue because of the window track. Be sure that speakers you use are shallow. As for mounting them you can cut off the factory mounting points for the original speaker and fiberglass in a wooden ring for back mounting larger speakers. This you give you a study mounting point and set up a decent baffel. 6.5" speakers tend to be too wide as well as too deep so I would go for 5.25.
