I'm changing my rear side panel speakers in an 04 coupe this week... But i'm trying to find some spacers to ensure the speakers will fit properly. Does anyone know where to purchase these adapters/spacers. I'm also looking to dynamat. What is the best cost wise type of sound insulation that i can purchase? I'm doing the whole install by myself and need some recommendations. thanks

 

I just ordered these to install my door speakers.

Supposedly the same spacers are used for the rear side speakers.
