Here is the fibreglass box that I made for my MSP. It fits behind the wheelwell and the rear tail light, taking up very minimal space. We are currently producing these enclosures for sale at a price of 350 US, plus shipping The box will only hold a 10 inch sub, due to the reduced volume available. A matching enclosure for the other side is in the works and will be able in about 2 weeks. I will post a pic of that when it is completed.
