Okay, My little 2011 Sierra is a simple Work/Truck version with no options. I ordered carpet from "stock auto interiors" and I bought Infinity 6.39i speakers plus 4x6 Infinities for the rear post. Also I wanted to take out the center jumpseat/seatbelt assembly to have a two-seater pickup truck.
It's all done now. It's very open and roomy now. You can do the same thing on a crew cab and you will have "walk to the back" ability but you'll sacrifice a front center seat or the console... your choice.
Some simple hints.
1. Seat bolts are an external star tork design but a 11M socket (rear bolts) and a small sparkplug size socket for the front bolts (both 6 sided) worked wonders. I had the seats out and center seat removed in 30 minutes. OH.. you'll need to get a TORK driver set to take the seatbelts off of the seat and to remove the mounting on the sidewalls. I got a TORK set at Harbor Freight for 9.99 so don't pay too much.
2. The carpet was "factory molded" to fit but it did need to be trimmed after placed into position. I went with "mass backing" and I'm very happy that I spent the extra for it. The carpet is fantastic, much better than GM stock.
3. OH.. door threashold, side panels, and rear window ledge trim panels snap off easily. Just be gentle and pull slowly. There's one small screw at the top of the side panels (one each). Speakers were installed with silicone and 4 self tapping screws.. I just hooked up to factory wires after stripping 1/2 inch bare wire. Easy.
4. I took someone's advice, not sure if I had to.. I did disconnect the battery before I reconnected the seat airbag wiring. I did it this way, not sure if you have to.. BUT, I did not blow up a seat.
Pictures to follow.. I can tell you that this is one smart little truck now, the carpet, center seat out, and the sounds are wonderful. I did this all in one afternoon outside my condo building.
Let me know if you have questions.
