I've been emailing back and forth with someone from this website that makes adapter for all cars, I've asked about an adapter for our car. For those who have a Bose system, the coupe door speakers are actually 10s and if you want to upgrade your sound, or swap to a smaller size speaker, an adapter would be needed, anyway the guy gave me a link here and he said this might be compatible.

He also said if I can give him the exact measure from
hole to hole, he'll be able to tell me if that will work or not. If it doesn't he can make one for our car. I'm wondering if anyone has take out their door panel or and can give me the exact hole to hole measurement?

 

PM Ivoidwarranties... he also has a DIY to remove door panels I believe.

 

anyone ever try these?

looks like they have the tweeter mounts also

pricing is nice being that you wont have to have the headache of making them

 

took my door panel off my 2011 Sedan with base audio (non bose)

the speakers are different.

Looks like the same speaker shape used in the G35s.
Im thinking about trying the G35 speaker adapter
