Podiums for acoustics in the door. - Toyota Sprinter Trueno, 1.6 L, 1992

In place of the regular speakers I decided to make podiums for 16cm speakers, I cut out the base from the foam, pasted it over with fiberglass with epoxy, grinded it, putty it, and painted it in matte black from a spray can.)) I still have not bought the speakers, I will use a spacer, I will make similar ones for tweeters podiums.
