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.
Thank you for the response. Mukhang ilalagay ang Pioneer HU sa ibang sasakyan pero ipapasa sa akin yung 2 Din unit mula sa sasakyan na yun (I believe it's an AVT HU) mukhang may sub out port naman yata sa likod.

Ito po ang mga nasa akin ngayon: (karamihan ay pinamana lang)

(AVT) 2 Din HU
Infinity Seps
6.5 inch Digital Design sub with enclosure
Kinetic KD70 amplifier
Double din audio panel for GE Jazz

I live near Banawe din (Villa Espana) at naghananap ngayon nang mag install, may ma recommend po ba kayo na malapit na mahusay mag install? Lagi ako napapadpad sa Candyshop kaso parang ilang oras na ako nakatayo at nagpapa cute dun at nakikipag eye to eye contact na sa mga employees at sa may ari yata kaso dedma lang sakin (maayos naman ang suot ko at mukha namang may laman ang wallet :p) may ma recommend ka po ba and any other suggestions? should I add anything or change anything sa lineup ko? I am also opting for sound deadening, may shop po ba na gumagawa nyan sa Banawe? Maraming salamat po! Hoping to get this project done tomorrow :D
