    sigle box or dual box

    im building a new box for my 2 alpine type rs im goin sealed cuze im putting the sub inverted and i have no space for ported that way, and im going 1 cuft for each sub, but now im at a dilema, 2 cuft single box or split box 1cuft each chamber? do i get any pros and cons on any of those configs?

    im more inclined to do 1 box, 2 chambers.....

    they will be push by a monoblock amp parallel 1 ohm

    i just saw this thread.. didn't know u got alpine., u coming up in the audio game huh? biggest reason to do separate chambers is if 1 sub messes up u can still use other one..

    Re: sigle box or dual box

    If you do 2 separate chambers you could put a relay on one of the positive cables and turn one of the subs on or off for demo purposes otherwise common chamber saves wood and often lowers the peak frequency of the box 1hz or 2hz which is normally good.

    I also see no reason to run inverted unless it it for looks and depending on the sub, I am unfamiliar with the alpine in particular, you could have some motor noise that would otherwise be muffled in the box.

    i was thinking about updating my build, but since i updated last time and no one care about it, i think theres no point on doing it, why keep up updating the build here if i do stuff, posted photos and plans to do next and not even a reply there, new speakers, sound deadening, new wiring etc etc and not even one reply... so whats the point of posting

    Being way stronger isn't always needed and you can add bracing without making two chambers.

    Inverted is fine, not my taste and not really possible with the JL 13tw5 that I run. I really only have ever run inverted with monster subs like dd9500, is death penalty, sundown z series beyond that I prefer my cargo room. But my taste mean nothing in your vehicle

    Re: sigle box or dual box

    in this case is a good thing cuz they will be facing down with a sligth angle so the center support between the 2 subs is goos so the box dont curv down
