So you dont have to worry about series and parrallel. You just plug the amp FR into the front right,and so forth for FL,RR,RL...

I dont recommend using the stock amp for adding an aftermarket subwoofer. The easiest solution is to purchase an amp with High-pass input so you dont have to wire back from the radio, just from the stock sub jack.

I had an 8 ohm sub in my old car.

If you want to use the stock amp, call the dealer to find out the ohm value of the amp/speakers, then match the new sub.(or your speakers will be messed up!) Equally as important is the RMS voltage. Be sure that the RMS voltage is near the RMS of the amp and the other speakers, or the sub will overpower the amp or vice-versa or the sound levels will not be close...(example, if the rms of the sub is lower than the rest of the speakers, when you turn up the volume the sub will increase in volume at a greater rate than the rest of the speakers.)

Subwoofers come in 2,4,6,8,10?,16 ohms and with various rms values.

Best of luck.

Dave
