I have a 2005 2.5 si with the premium and sport package, convertible, and I believe it has the 10 speaker system. I need actual speakers sizes for whats in the car as I am going to upgrade the whole system. I just installed a Pioneer AVIC-N3 flip out but it doesn't like the factory amp and speakers thus I get clear sound but about half the volume capability the factory system had. Rather than tear the car apart just to get the sizes of the speakers I have been trying to get them online so I can just order accordingly. Does anyone have these? You can email me the list at
lws5150@aol.com if you would. Thanks guys - Z4's RULE tHE WORLD!
