I don't even know if you can call it that... I've seen it on some A4's before and it really looks nice, its like a very short kind of stub on the edge of the trunk hood... some people on this forum have it. If anyone knows what I'm talking about can u tell me where to find it?

Also.. I know this is a topic that has been brought up countless times, and I'm sorry to bring it up once again, but what are the speaker sizes for the non-Bose 2004 Audi A4 (I'm pretty sure it's stock, I have 10 speakers). I keep hearing between 6.5 and 5.25 inch speakers.. but does anyone really know what's suitable for my car's certain set up?

 

its the m3/m5 spoiler from bmw. i think most people find em from online stores. i dont have an audi, but im pretty sure that thats what there called. google it.

speaker sizes i have no idea. google that too

 

i googled the speaker part heres one of the main sites

clarification on the speakers. stock there 4 inches in the front, but can be sized up to 5.5 w/ a kit.
