Well first off I own a 04 Mustang. So you know it's hard to fit anything in that trunk. I can fit two 12's in individual boxes in there however the boxes themselves aren't to big and sealed at that. I need advice on 12 inch subwoofers that work well in small enclosures. I was looking at the Pioneer TS-W3002D4. They claim to be designed for small spaces. Any input or suggestions?
