Can anyone tell me what size speakers I have in my 05 XLT Supercrew? Also if you guys know of anywhere that I can buy a custom box already made for the supercrews to fit 2 10's or 2' 12's and go under my rear bench seat?

Thanks,
Nick

 

The door speakers are 5 by 7 / 6 by 8. As far as I know, ive never seen a prefab box that will hold two twelves that goes under the seat. Ive only seen boxes for 8's and 10's. three 8's will operate better in that space and give you the same depth and SPL as two twelves of equal quality and power if the box is ported and tuned to 40 hz.
