Hey everyone.
I've never built a fiberglass enclosure. Getting ready to start an install for my son's 2013 Ford Focus HB for his birthday. Going to flip the spare tire and do a FG enclosure inside the spare tire for an SI BM MK IV sub or an Alpine type R shallow 12 (have both), depending on how much space we can end up with.
I've been reading tutorials and watching videos on FG techniques. The one thing that I am unsure of is the best way to attach the MDF top of the enclosure to the FG lower portion.
I've seen guys wrap the fiberglass up and over the top of the MDF, but it looked terrible.
I can see that part of the problem might be that the fiberglass shape might not be a flat planar surface to mate up well to the MDF. If it isn't flat, what is the best way to join the two? Construction adhesive?
I've seen other fiberglass jobs where they mated the main enclosure to the mdf panel by stapling some material to both and fiberglassing together.
I did a quick sketchup drawing to show what I am planning. Any advice from the experts is greatly appreciated.
