I looked for an hour for something related so forgive me if i'm blind and missed it. I'm wondering if anyone has ever built or had a custom box/false wall built into there trunk. My box is to big for my Alpine s type 12" sub. On top of that it rainded like a mother the last fours days and the carpet piece and the carboard piece are soaked. My box is wet underneath that too. Luckly my amps and gear are mounted on a piece of wood to the support beam on the back seat. I had my rear door spekers moved to the rear deck and they cut a port in my rear deck because I was going to have the box/wall done later. Has anyone else done this and or had water problems in the trunk either?
