Finally got away from the prefab boxes taking up all my cargo space. I took cues from the wicked cas box but never liked how they covered up the courtesy light. So I went passenger's side. The wicked box wouldn't have fit with my exising amp rack anyways. I also wanted something that allowed for easy swapping of subs whether it be a different brand or a different size altogether. My box has a bolt on baffle. I can go with single/dual 8's, or a 10 just by cutting a new baffle.
