Well, this Monday I started my first ever fiberglass project. I am making doorpods for my DLS 6.3 3-way component set. I started the back half fiberglass enclosures. These will be part of the the sealed enclosure for the midbass. I utilized the factory 5.25" mounting cup, and filled it to create half of a sealed enclosure. This mount/enclosure used to bolt to the sheetmetal of the door, and the plastic doorpanel is mounted in front of it. Since this mount is being replaced with the rear fiberglass enclosure, I am guaranteed a perfect fit, dont have to cut any sheetmetal, eliminate depth concerns, and will seriously increase the imaging, depth, etc.. I removed the OEM speaker grilles from the doorpanels, the rear half of the fiberglass enclosure will be portruding through these holes, thtough to the surface of the doorpanel, where the baffle will be glassed/molded into both the rear half fiberglass enclosure and the surface of te doorpanel itself. In the end the midbasses will be completely sealed, and the finished product will look as OEM as possible. The actual MDF speaker mounting baffle, which will hold the midbass and the 3" midrange will actually be in front of the plastic doorpanel, and the surface of it will be glassed, and molded. Basically, this is the least intrusive, but most tedious and hardest way to attack this. More pics located here. *note Those OEM grilles in the doorpanels probably throw off the mental picture you will get. The baffles will actually be mounted parallel to the bottom ledge in the doorpanel, the midbass closer to the firewall. They will also be pointed up at an agle vs. firing at my ankles. I will take another pic and update tomorrow with the cardboard templates I made showing what the mounting will look like. Keep in mind that this is my FIRST EVER fiberglass project. I read a lot of tutorials, so I think I got most everything down pat. The mat I have is pretty thick, and I had a hard time getting it to lie flat around some of the edges. I will probably lay down another layer tomorrow...then cut my baffles out (you can see the preliminary design lined ou on that sheet of MDF in the background in some of the pics) and then blend this enclosure to the baffle with more glass.
