Hello everyone. I am thinking about upgrading the stock system in my 13 SE. Replacing the factory front components with some aftermarkets and adding a small sub to the back. My question is has anyone done a custom eclosure for the hatch area? I want to take up as little room as possible as I am always hauling my road bike around. Not interested in removing the space tire either. Any thoughs would be appreciated. Or any suggestions on a very shallow mounted sub that would take up as least space as possible. Thanks!!
