VR4 power.
did this some time ago, only had phone pictures of the build. i believe it is 4.4 cubes tuned to 38.5hz and 56sq.in. of port.. i decided to have the ports extend into the trunk due to the lack of airspace for the 15.
cutting the ports to length from the 10' section
glassed the inside and braced with 2x 2x4s
removable ports, these are the 38.5hz daily ports
did about 2-3 layers of glass..used a ton of resin, my dad did have a 500gal drum so i think it was about 3 gallons though. good thing it was winter resin so it set up quick with a little added heat.
