It probably took me over a year before I finally decided to work on mine, from day 1 of installing the PDX amps on the factory tray I was never 100% happy with the fitment, flexibility of it etc.
One thing I forgot, I need to add a little more strength to that piece the subwoofer sits on, as you can see from the pic it is still bowing more than I would like it to do. I'll probably just double up the wood thickness on that piece, just need to pop some staples from the carpet so I can screw and glue the wood to the bottom.
