And now for the false floor section.
I initially cut out a piece of wood that would fit over the two supports on either side of the subwoofers that was all one piece. However, you have to hinge it in order for it to fit inside the vehicle. So I took the solid piece and cut it on one end to make a hinge.
I had my sign guy print me up a Lexus logo and then I used that logo to trace out the Lexus emblem on the piece of wood. After some jig saw work, I had a Lexus logo in the middle of the piece of wood.
I bought carpet from Parts Express that was/is pretty close to my original carpet color and cut it out using the factory floor piece as a template. I then put the pice of wood on top of the carpet for a test fit.
The blue tape is to outline the edges of the wood so when I put contact adhesive down I don't go overboard. I then coated the wood and the carpet with contact adhesive and put the two pieces together.
After that, I stapled the carpet to the back side of the board and then followed it up by stretching grille cloth around the Lexus logo opening.
