first board is 1” mdf secured to the floor using the factory seat belt studs with large 3/4” nut countersunk flush (out of the way). Then the 3/4” platform has something flat and sturdy to rest on. It will be secured with SMD Blackjack #15 high load fasteners onto the first board. Then, using something hidden and equally as strong, the box will be mounted to the platform. This thing aint gonna budge. #smd @dcsoundlab @wccaraudio
