If you have a custom box that maximizes trunk space and allows you to keep your ski pass thru i.e. box installed on the side. in your trunk. Could you post a couple pics here so that I can have an idea of what I can do? All I want is one 15" subwoofer in my trunk. Also it would be cool if you can show where you put your amps too. That would help alot. I searched the forums and couldn't find any pics. Thanks!
