Hey...I have a 94' GMC sierra ext. cab and i made a kick ass box for the back with 2 10's and my 6X9s...fist i made 2 seperate boxes for the subs, one for each side of the hump...then i made a piece for the 6X9s to connect the 2 boxes that makes it look like one whole box...its not carpeted yet but will be soon. here is my sight for more pictures GMC Sierra
