Cross-overs and amp secured to the Mark III board.
I used 1/2" nylon wire fasteners to secure the 4 AWG power and ground wire. I also put a couple of washers between quick disconnect and the board so it would have less interference when connecting.
I also added some simple black cabinet handles on each side of the amp. With the weight of the amp being off-center it was a little awkward to pick it up by the edges. With the handles on either side of the amp, it is easier to pick up because you're picking it up where the weight is located. It just makes it easier to position the hole over the carriage bolt.
