as our experience the newer d-max has less space beneath the rear seats for a subwoofer box compared to the old one.

So far for the newer Max, what we have installed were two powered subs like what memps has and just separates sa doors. we have a plastic molded tweeter mount that replaces the original plastic in the doors, the small triangle one. Wala pa may nag pa set-up talaga ng new max so hindi pa talaga namin ma try what the biggest sub with the right box configuration we can fit.
