Can I install an aftermarket sub with no aftermarket H/U?

I want to add a single sub in the trunk just so I get a little more bump but I want to keep the stock dash look. Is it possible to wire the sub to the stock amp that is already in the car or would I have to install a second amp? I know how to do wiring and stuff, I just don't know how to setup up an audio system correctly.

I just got 2 kickers installed with an amp into my stock H/U. but you probably need a second amp to power the sub to make it sound good.

Not sure what you are referring too. The input would be the speaker wire to the current sub. Run a fused power line from the battery and you can either ground it to the chassis in the trunk where it's mounted or you can run a ground wire back to the battery. For the remote turn on you have a couple of choices, best choice would be to tap into the amp remote wire of the stock unit (blue/white tracer) or tape into any acc power source. If you go with the amp trigger unit will only power up when the radio is on, if you tap into any acc source then it turns on with the ignition. Bolt it to the floor of the trunk right behind the seat and you'll be set.

I suggest figuring out (using search) which wires are hooked to the rear speakers of the car through the amp and tapping into those. They will not have nearly the power output, and you need to tap all 4 wires (left +/-, right +/-).
This is not a good plan. Ground should be as short as possible. Keep in mind that power travels from negative to positive. Shortest path is best.

Did not think the stock sub amp was powerful enough to overload the high level inputs. Did not know about the signal sensing circuit either. I have heard an installed basslink and found them to be an adequate alternative to the stock setup but I've never installed one. Good info, thanks.
