DIY build - need help/advice

[MercedesBerater 268]

Adding poly fill to the one side (easier to get to now)   Then I’ll find some time do add the right side wall & clamp up. 
and need one more sheet to do a double baffle and then I’ll have a third sheet on the front with 45* decorative edge around speakers and the perimeter of box.  Technically a triple-baffle, but the speakers will only bolt into 2 sheets.

@CECAA850  - yes  subs will bolt through 2 layers of 3/4 cabinet grade MDF   (i spent the extra for the good stuff from a real lumber yard, instead of the cheap stuff from Big blue, Big Orange, Big Green.)   then, around the subwoofers there will be a third sheet  with a 45* bevel around subwoofers and 45* bevel around the front face.  make them look recessed, and add some more stiffness - but they won't bolt through it. so not sure if that counts as a triple or double, or a deuce and a half.

Cabinet grade mdf is the only way to go.  The big box store stuff is called mdf but is more like particle board.

I'm curious where you bought from. If you are in Roscoe, I live 15-20 minutes from you; I'm North of Belvidere

@capo72  Schmeling in Rockford - ask for Adam Kinkaid.  good dude.

Test fitting the holes before adding second layer of MDF.... tested again... then added the 3rd layer for a recessed fit with 45* chamfer — I didn’t do a full chamfer on it, I started it right where the basket ends- I thought that would look more seamless. 
 

working on bondo on the seams... and making nice and smooth.

 

then I’ll round over all the corners & add a 45* chamfer to the perimeter of the front  then cut out the vent and round over the top and bottom edges.  ( I think I’m going to leave the side walls squared off) 

 

started shopping for paint codes.... 

leaning towards  Bentley Beluga Black with a buffed and polished finish for a high gloss. Then probably ceramic coat it to prevent scratches and swirls in the paint.
