Has anyone done this or thought on it for a bit. By my calculations you would have to make the box a bit taller but it would still fit and have room between the floor and the sub. These subs can take like 300-400 watts rms compared to the 150 from most shallow subs. Does anyone have any comments on the subs themselves do they suck. Ive only had one set of subs before and they were rockfords but I bought them a few years ago and that set up wont work in my jeep unless I take up the rear seat space and Im not gonna do that but I need some bass and the factory sub just isnt cutting it. thank you for any constructive comments.
