I'm pretty much a noob when it comes to systems, so simply put, is it possible to run two 10 or 12's while using the stock head unit?

 

It certainly is, although there are some things you should know about doing it. First off, the HU (stock or aftermarket) has nothing directly to do with running the subs. It only supplies the audio signal to the amplifier that is powering the subs. Second, to use the stock HU you'll need at the very least an LOC (low output converter). It takes the audio signal going to the factory speakers and converts it to a low voltage signal and has RCA connectors that can then be connected to the amplifier's inputs. Or use an amplifier that has "speaker inputs" or "high inputs" that can take a signal directly from the factory HU into the amp and does the low voltage conversion internally. The latter is about the easiest way to do it, however those inputs are getting harder and harder to find on today's amps.

If you can give us an idea of the budget you have to work with and the goals of the setup we could help you further. Why don't you want to change the HU though? Done properly the truck can always be put back to original and your equipment taken out if that's what you're worried about.

 

Cause I simply want to run two 10s or 12s but keep everything stock looking other than that. I plan on going pretty cheap as I've had Pioneer before and I was happy with them with my beginner taste. I've ran two 10 inch Pioneer subs in an S10 before with a 760 watt Pioneer amp before and I liked that set-up. Im thinking of running Pioneer again with two 10s or 12s in a ported box and about a 1000 watt amp.
