Where can I find some MDF speaker spacers for the front and back of my daughter's 2006 tC? My understanding is I can use the spacers to get a 6 1/2" speaker to fit. Is this correct and how deep can the speakers be to get them to fit correctly. Thanks.

 

Here are some from Elemental Designs.

Shoot elemental designs an email on their website and I'm sure they will give you better specs for what will fit. I have contacted them about a subwoofer box and they were able to give me all kinds of measurements quickly.
