Look at my youtube video. I'm tired of this prefab box. I'm going to fill the trunk with batteries and amps. I want to either take out my back seat and make a box to fill the back, OR make a wall. Problem is I need to see out my rear view mirror. So here is my idea. A slanted wall! Wall running at an angle from the back of my seat, and up to the deck lid in my car. Closing this off just like a wall, but angles up so I can still see out of my rear mirror. Ideas? Opinions? Plans? PM me if you have any ideas or reply here! Thanks!
