Hey guy's let me start off by saying im new to the board, im in the crossfire of buying a mojo 15 or sundown zv4 15, don't really know which is the hardest hitting sub between the two. I have a ford focus se (trunk type) and im debating on doing a custom box in the trunk or inside the car and remove the backseat. So im asking for some help on which sub is the best and the best way to build the box. This will be a single 15" build BTW. I will be using an extra battery, 0 gauge wiring, 3500 amp. Thanks
