So, I upgraded the OeM alpine sub to a Kicker Comp 8” shallow mount and installed a Kicker Key 500.1 to run it. While it is miles better than the OEM sub, this is my first ever 8” sub (and first junk box as the OEM is), and it’s just not enough. I’ve decided to build my first fiberglass box and install a Kicker L7T 10” solobaric sub under the drivers back seat. This will free up the larger passenger side storage area and I can keep the larger passenger side fold flat floor. I intend to keep the seat at the same height, so I need to figure out a way to keep the box profile as low as I can.
ive build tons of boxes, but I’ve never worked with fiberglass. I know resins quite well, and have used all kind of epoxies at home and work, so I’m not too fussed about that. The biggest concern I have is mating the fiberglass to the MDF I’m going to use for the top. I’ve seen a few builds, but no one really addresses that part. Also, where the edge of the box will be toward the center, the under seat compartment is kind of a valley right there. Any tips on how to close that gap would be helpful. Basically looking for any general tips that can help. I know to tape the ever living **** out of everything. Some people say to put foil down, some people say it isn’t necessary. I’m not worried about aesthetics on the bottom, as it won’t be seen. I’m going to make a ring of 1/2” MDF to attach to the fiberglass, and a solid 1/2” MDF board for the top where the sub will sit. I’ve thought about another MDF sheet to “countersink” the sub, but I’m not sold on that being necessary.
any help would be great. Thanks in advance.
