Ok ya’all I thought this post would be to tell ya how I maximized the under seat fan ordeal. But. I will start with the plan. I built a console to sit on floor in middle and was going to use it as a plenum, had vents pointing up and out the sides, sealed it with foam strips between the front of the seat, mounted a reversible 8” fan under the seat with a shroud against the front panel, cut vent holes in panel and thought because this fan moves more cfm’s it would work great as heater in winter and get rid of the heat otherwise. Well... for some reason it works great as a heater but not so good to get rid of unwanted heat. I haven’t given up on this setup yet but I would recommend staying with the bilge fans. So far I have 20$ in everything so not a big loss but am going to build a new console and try to get more air flo.probably end up buying bilge fans. Lol
