Some trucks came with this from the factory, like the Tremor sound package. I think you would know it if yours had an amp and sub, it sounds so much better. So that what those connections are probably for. Unless you can find these for cheap, with the oem wiring, I'd say just upgrade your headunit, and then wire an aftermarket sub and amp to that. It'd probably be cheaper in the long run.
I'm sure someone will chime in that knows for sure. My truck came with nothing but a radio, no cd player, and two crappy paper speakers up front. Didn't even have rear speakers.....that set-up lasted about a week before I upgraded.
