I've been wanting to add a subwoofer to my renegade, but can't decide on where to put it. I have a big dog, 115 lbs, that barely fits in the back as it is. So, I don't want to just throw a box in the back and call it good. I wish JL made a stealthbox.. I think there are shallow mount woofers that can fit under the seats, but I'm not confident that those will have enough bass. Has anyone added a subwoofer to their renegade? Pictures would be great.
