If you're talking of 3-way 6 x 9s vs. seps, normally kasi ang seps sa harap kinakabit. Ang 6 x 9s sa likod. Ang seps kung tutuusin 3 way. I think may 2 way din. Bale 1 tweeter, 1 midrange and 1 woofer. Ang difference ng two is that with 6 x 9s, hindi 'separate' ang origin ng sound mo. According to a CSGer, walang 'imaging' therefore it drowns the sound. With separates, normally iyung tweeter mo nasa dashboard nakapatong. Whereas, your midrange and woofer nasa front door.
Kung nagtitipid ka, I guess based on feedbacks mag targa ka na lang
