Anong ride niyo?

kung ok lang ba na apat ng 3 way speaker pioneer 220 watts lagay ko 6 inches size ng speaker (one speaker on each door )
Dude overkill yan. Its either you put a two way seps up front or a two/three way coax, at the back just put a coaxial speaker no need for a two or three way since your only gonna play lows. My choice, get the two-way seps (if your on budget), or a 3-way if you have the moolah (fabricate kick panels and/or the A-pillars). Since you want a SQ setup the staging should be up front the rear speakers should only complement the subs.

kung mas ok din ba sir na seps ko na lang ang two speaker ko lagay ko sa rear at maintain ko ang 3 way na sa front
Sayang lang pera mo pag two way ilalagay mo sa likod kasi di mo magagamit yung tweeter. Coax pwede na.

ayw ko na kasi lagay ng mga ampli or subs wla na space pa kaya SQ lang trip na sounds sir
Kailangan mo ng amplifier, you can put it under the front seats. If you don't use an amplifier, you won't be able to maximize your component speakers, kung sa power pag gagamitin mo HU lang. Ok lang na wala kang subs, just juse your rearfills as your base.
