I had a member contact me and he had me make him a set of 3d printed rear deck sub adapters. If you want to get rid of your boxed sub and take your trunk back, this is the solution. I’ve found the perfect sub for the job and they are not expensive. I printed an extra set of these and can can print more as needed. They come fully assembled with seals on the deck side and speaker side. I include screws to mount the speakers too. You will need to do some light cutting on your back deck or use Vice grips and bend the hole open a little bigger. These sound way better than you’d expect!
