Hope this works.
Amp rack before the final cover is in place. Without the cover water from the wakeboard rope, or from large waves would get the front of the amp wet, which wasn't good.
Amp rack with plexi cover installed. Painted flat black for now, going to change to gloss black later. Would have painted white, but it would scuff and show marks too easily.
Screen mesh I installed beside the amp to allow air flow behind and around the cooling fins. There is an exhaust port at the back of the boat, so airflow naturally wants to go through that opening at out the side/rear of boat.
Other side of boat (identical to amp side). This is what the opneing used to look like without the rack.
Source that drives it all. Nothing special.
Front drivers speaker (one of 4 speakers total in boat)
Custom sub built into boat. No loss of leg room. The 5/8" mdf box is sitting in an unused cavity that was being used for nothing before the box was added. I was contemplating a location, and with the sub downfiring, the bass is extended well throughout the boat, and the passangers are also comfortable because they can still extend their legs in the area below.
Total cost on this project: $200 I think. All materials I used were scrap. Leftover plexi and MDF. The amp was $65 used. Its a 5 channel pioneer amp in rough shape. I sanded it smooth and painted silver. The sub was $15 on ebay. Speakers were from my car before I upgraded. All wiring was leftover (4 awg welding cable and dist. block etc). Deck was $100 or so.
