A3 front speaker adaptors

They are plastic, your better off making them yourself out of MDF

I'm pretty sure the door speakers in the front are the same size for both 3 and 5 door.

Hi Jay

They are useful as templates, but not really robust enough to actually use on the door cards. If you PM me your email address I can send you the MDF templates I use to make my own. Bear in mind using MDF does encroach on the limited mounting depth you have in the front doors. The plastic ones will give you an extra 8-10mm, so depending on what speakers you're fitting you may have to use the plastic ones. Just be prepared to use some silicon sealant or hot glue around them as most of them don't seal properly against the door card properly and Dynamat as much as you can.
