    Hey all, I'm just wondering if I have to get a new HU to add a jl w3v3 8" and a crap amp into my truck? I have a decent HU already out of my old sonoma but I actually like the stock dash/HU and wouldn't mind keeping it if It can simply be add'd on?

    Its a 2010 Sierra EXT Cab, Nevada Edition.

    Ditto above.... With just a sub added to the factory radio you should be fine..

    Also, PAC Audio makes some great stuff to connect into OEM systems. For my 04 Z71, I got to give me RCA outs and a remote wire, without having to cut and splice the factory wiring. Just plug it in and go. They also have several similar things for the newer GM vehicles with CAN bus and GM-LAN. You might want to check them out.

    So I would just need to run the power for the amp from the battery then? and splice into my rear speakers to get my audio signal?

    X2...... plus since this is directly out of the back of the deck you'll get a better signal then you would by splicing into the factory speaker wires.

    so for that I would just plug that into the harness on the OEM deck, and I would still just need to find a place to send the power from the batt to the amp, and robert's your fathers brother?

    Pretty much, yes. It's a little box that plugs into the back of the radio, and the truck's harness plugs into it. And it gives you a remote and rca connections. On the one I got from PAC, I had to hook up the remote to the right wire in the harness, as it was left disconnected on the stereo side, as it is different on some years. But did not require altering the existing harness at all. Then you just have to run the remote and RCAs back to the amp, and the power and ground for the amp, and you're set, aside from tuning and hooking up the sub.
