Project Fit – FatMat Deadener Install on Hatch Door

I installed 6 sq/ft in the Project Fit tonight. I did the hatch door and did a small piece on the license plate too. The hatch door comes off via 2 push pins, and a center plug deal. You can remove both via a small flat screwdriver. The handle inset also needs to pop out. I used the same screw driver to pop it out.

Update 3/2/13 – See my review of FatMat here.

I actually took this picture after but here is what the OEM Fit hatch door looks like with the trim on.

I circled all the pieces you need to remove to get the plastic hatch trim off. Once these are off you just pop it off, like a door panel. Plastic clips hold it on, so pull hard. Some might stay on the hatch, just use pliers to pull them out and stick them back on the plastic panel before installing it back on the hatch.

Stock 07 Honda Fit Hatch door with plastic trim removed, no sound deadening at all. The plastic trim piece has a small bit of felt on the backside, I didn’t take a photo of it though.

Here it is almost done, just a bit more deadener to go.

DIY Slot Ported Box Build with 4 Lanzar MAX10D Subs for Project Fit

I finally got some 3/4″ MDF to build the box for the Lanzar MAX10Ds I got so this post will feature my design and a few build photos of the enclosure. It is 5.4cu/ft before woofer and port displacement, 4.4 cu/ft after. This gives each sub 1.1 cu/ft. The box is tuned to 33hz and features a rear mounted slot port, the woofers face up. The port size could be a bit larger but I figured it will do, it is 18.5″ x 2.5″ x 17.75″ long. This leaves about 5″ between the port and the front of the box.

Box layout from a single 4′ x 8′ sheet of 3/4″ MDF.

Box Specs 

  • 24″ x 24″ x 20″ tall
  • 5.4 cu/ft prior to woofer/port displacement ; 4.4 cu/ft after
  • 18.5″ x 2.5″ x 17.75″ long slot port (Rear facing)
  • 4 x Lanzar MAX10D Subwoofers (Top mounted) Wired to 2 ohm final load (DVC woofers in wired series @ 8 ohms, then all paralleled together)
  • 3/4″ MDF 8×4 sheet (didn’t use the entire thing)
  • Elmers Max Wood Glue
  • 2″ Screws (Lots)
  • 1″ Screws to mount woofers. If I had a double top plate I’d use the 2″ but with only 3/4″ no sense using longer than 1″.
  • Total Cost – $96 for 4 Woofers, $33 for the sheet of 3/4″ MDF, $8 worth of Screws, $6 Glue = $143 plus carpet and a terminal cup.
