i had a smaller amp under the false floor but i upgraded to a bigger amp after and just put it on top of the floor. the whole box costa bout 200 to make with all the materials. i went to a boat hull repair shop and ordered all the fiberglass resin and cloth. it hit really nice untill all got stolen before christmas now im a broke radioless fool who will never put a stereo that big in ever again.
it took 3 days and a few 12 packs to make. if you want more ind epth photos or instructions let me know .i got picture of it in the process of being made also.
