few updates being spread over a few posts. The first I added a quick disconnect panel for the cables running through my wakeboard tower for the lights and speakers. I purchased the plugs and bulk head connectors from Amazon. The large black ones are for the speakers, I used the same type at the speakers them selves a few years back and work great, they push in twist and lock. I always just ran the cable through small holes in the boat never giving thought to what if I need to remove the tower now that wont be an issue. The smaller metal one in the center runs the 12V and ground needed for my 3 different color LED lights built into the speaker box. I 3D printed the mounting plate for them, sanded it down and painted it with high gloss black.
