Is there a way to put a sub box in a 1976 F250 with a In cab tank? I cant think of anyway but im sure there is a way. Can someone help me. Thanks

 

My buddy had a '74 with three tanks, 2 bed 1 in cab. He removed the in cab tank and built a box behind the seats for 4 12" subs. I had a '78 with 2 12" subs, each in its own box, and still had room for tools and gear. I say remove the tank, unless it's your only one...
