I have a 2000 extened cab CTD and I was wondering if ther was anyone out there that built a custom enclosure for there truck. I got a good deal on some 10 inch deep subs for my truck but they are way too big for a premade box. I have seen someone with a long bed cummins with a sleeper on it for the subs in it. I have thought of goin that way if I cant figure anything out.

 

You might have to lift your back seat and put them under there.

 

i don't know how big your magnet is but i used a 10inch truck speaker box with a slight slant to it so it sits behind the middle part of my seat and fits perfect.you can also get a custom box that sits under the back seat.i had one of these boxes in my gmc and they look factory.
