I am using a box I had built for my Sonoma standard cab that housed a 12" Boss sub in a ported box sitting behind the driver's seat in my K1500 right now. Planning on designing a box to fit two 12s under the back seat using a pair of Memphis Audio subs.

Looking for some pictures of extended cab subwoofer set ups. Thinking of building a fiberglass box under the rear seat with some 8s or 10s in it and would like to see what other people have done to get some ideas. Also looking to see where everybody has mounted their amps, I don't really wanna just screw them to the back wall but idk where else to mount them. I have one of the older 1500bd1 Rockford amps and its pretty big so I don't think itll fit under the front seat.

Custom box in 88 extended cab fiberglass under back seat two low profile 10's will send pics of it installed later just had to replace subs lol
