2000 Ext. Cab S-10, box for one 12 pyle

Ok, we need the air space requirements for the sub, then the measurements from the vehicle (the area where the box will go).

Mr. sobriety has the link there for you.

power peak    1200

thast all i could find on the sub. i tried to use winisd but no luck. and as far as the space i dont care how big the box has to be. just make it square.

Ok, make a box that is 15.5"(width)  x 15.5" (height) x 15.5" (length) with half inch stock. This will net you an internal volume of 1.76 cuft and a damn square box. 

I guesstimated on the volume requirements.

OR

Buy a prefab box and be done with it.

Ummmm....

I think someone just made up those specs you found for that sub.  EBP of 27??  I second the notion of buying a pre-fab box that fits your truck.  To hell with how big or little it is.
