Hi Guys

I would really like to replace my front door speakers on my 1999 A4 1.8T.

I'm not sure what size (4" i think)??

If anyone has done this already please tell me which speakers they used ???

Thanks

If you search the archives (see left) you'll find a lot of discussion on this topic. Here's the basics: Yes, the stock front door speakers are 4", however there is room to mount 5 1/4" speakers. Lots of people have done this, most using custom adapters made by MBQuart for the A4 (see www.mbquart.com). Speakers others have installed: MBQuart (several models), Boston Pro, Infinity Kappa, a/d/s, Eclipse, and a ton more...
