hey scooter why dont you look into one of those mtx enclosures like surf has? It doesnt take up that much room and will give you much more airspace for a better sub so you can be louder and of better quality but the cvr shallow mount is a pretty good series from what I have heard. If the sub is a single voice coil than you will want to get a 2 ohm sub so you can get more output from your amp
