It's all in ur trunk. If you could make one that fits half of the trunk it would be good.Then put the sub in the middle of the box in it should sound good. you my want to slant the front mount were the sub goes so you can get better sound. But if your sub is 1200 watts of peak amd has 600 watts of rms. You would need a 600 watt amp cause its all in the rms so your coil wont get lose and blow of the sub. And it should sound good.
