    Default Sub enclosure, ported or sealed? Home build.

    I am planning on building a sub enclosure for a MM1040, should I go sealed or ported? Seems to me that building a sealed enclosure is easier but less efficient. I plan on putting the sub under my 02 sierra's rear seat, so I may have to get creative to fit it with only about 7" of space from the floor to the seat, foot and a half or so wide and maybe a foot long (sorry for not having exact dimensions at the moment). Its going to be powered with a pa880 unless any of you have any suggestions for an amp in the same price range that would work better.

    Finally getting around to this build, already have the deck in and the rca's and amp remotes wired and ready to be hooked up.

    A bit technical, but it gives you the pros and cons of both types oof enclosures. A sealed box will give you tighter bass with better transient response, i.e. a more even response in the range that the sub is playing. The ported will be louder but will have a peak at the tuned frequency and a sharp roll off on either side of that frequency. If space is a constraint then I would look at doing a sealed box.

    Sealed. Always sealed. Ported will give you a little more output but it wont be as good a quality. Sealed designs are also more forgiving of design and build flaws. Plus you tune your ported box to a certain frequency and everything below that frequency drops in output pretty quick.

    So if you want the most "musical" bass, go sealed. If you want the loudest noise, go ported.

    Sealed is easier to blend with your mids. Gives you an even bass response. Ported will be really loud on certain songs and then it will sound like the sub isn't playing on others.

    Sealed it is, thanks guys
    Gonna be running 12 guage wire to the sub from the pa880. 14 guage wire from the speaker amp (pa 250.2) to mm6501's
    relocating tweeters from the middle door panel to the panel that covers the bolts for the mirrors. Using a 4 guage power wire from the battery then splitting to each amp (fuses at the battery then fuses at the splitter). Does all this sound correct?

    Yup. 14 gauge would work for the sub too. 12 is a little much unless you're running 1000+ watts.
