Heres a review: Box looked cheaply built. Port not screwed in on one side nor gluing on that side. So port vibrated loose during shipment. Caulking not present on some internal edges, including 2 internal sides of the port.
I had to rip the carpet off and screw the port together on the bad side. I had squeeze glue into the seems, boy did i pack the glue. Waited a day, then caulked the crap out of. Reapplied carpet.
In the end, its working. Bass hits as expected, but seeing how to get it work, I might of just built it myself. Maybe would've been cheaper to use a buddy's table saw and other tools but I was lazy.
So you get what you pay for. Unfortunately I think I paid too much. Oh well...
