If you're loving the stock system over the current one. It's probably due to wrong installation. An inverted polarity speaker will do wonders in having that "wtf masmaganda pa stock ko" moments.
From the Pioneer 8450 head unit, do you have an amplifier powering your speakers? If yes, you have to check whether it has enough channels for a subwoofer. Most amplifiers come in mono (1), two, four, and five channels with four-channels being most common. If you have the four, the easiest way to integrate the subwoofer is to have channels 1 and 2 for the Infinity speakers up front and bridge channels 3 and 4 for the subwoofer.
As for the subwoofer, choose whatever you like. Do you need space? If yes and your aim isn't car-shaking bass then an 8" would suffice. Depending on your subwoofer, you will need to then design a box: sealed or ported? If you have an installer, you should consult him regarding your options. Most installers go for a 12" subwoofer in a 1.5 cu.ft ported or sealed box.
Where do you generally live ba? Seeing as you're around QC.. if you're around Banawe you can easily contact me as I live near the area and, depending on my free time, could help you out in your car audio Q&As.
