    Gonna try and make my own subwoofer enclosure soon. Never done it before. Gonna be using two Kenwood 12's. Anybody have:

    1) Pictures of their home-builts
    2) Minimum size requirements
    3) Other pertinent advice

    I'd like to keep size down so I can still carry a 33, tools, recovery gear and a cooler in the back, but I still want it to hit hard. Not looking for rap boom, but more into thrash metal and stuff like Ministry. Want to scare the rapper at the stoplight:D

    Thanks,

    John

    i would go with a sealed box. ported boxs usually need to be much bigger. your subs should have a spec sheet with them that will say cu. ft requirements. every sub is different.

    when you build it, i'd recommend using 3/4 MDF(meduim density fiberboard)
    and use liquid nails on all the seams. you want it airtight.

    i'll take some pics of my setup tomorrow when its light out.

    Yeah, like he said, you NEED to make sure the box is completely airtight. Liquid nails works good, or your basic caulk. I'll get a pick of my box tonight. Its unfinished, but you'll get the basic idea behind mine. It will house 4 15's in the back of my k5. Make sure you build according to the specs of the sub you decide to put in.

    These subs are brand new, but came with no box. They were salvaged from a tractor-trailer fire. Perfect shape, but no specs or model number or anything.

    i would look at kenwoods website and see if you can find your sub on there. If so, it should have all of the specs for the subs, and then you will know what size box you need.

    Heres mine, it is molded around the wheel well and it holds my 10" sub, sounds great and takes up hardley any space. It is made out of 1/2" MDF for the enclosure and I put a piece of 1/4" MDF over the front.

    Here is a pic of my box. The subs are 10w6 new series in a ported box. The box was made for my Z71 to go under the rear seats in it. The box is standing up, when laid down flat it is only 7" high.

    I used to have a book on building enclosures but have no idea where it is. Seems like there should be something online to give you specs. Anyone know where this might be?

    what series kenwoods are these?

    I've fiddled with the blue and silver tornado's, not bad woofs for the $... but they do take a little power to get going, and dont get very low - which doesnt matter for metal and such.

    the lower line kenwoods aren't particularly suited for a ported box, a 1.25-1.5 sealed box will do fine.

    here are some pics of my setup. two 12's in sealed box behind seat, false floor behind that housing amps on one side and tools on the other.hole cut in on side of amp box and computer style fan installed where old 4x10 hole is.

    now that i've built it i want to cut the false floor down to about 4-6" tall to get more cargo room on top. i realized i need more room for stereo gear, and the storage area is getting to small to be useful, plus there is a bunch of wasted space above amps.

    o also want add some angles to the speaker boxes to tie everything together. couple triangles to connect the 6x9 boxes to sub box. then a long "ramp"
    to make the sub box flow into the false floor. plus double as a hold down for the lid. also add some type of hold down for the spare tire. i used to keep it outside, but now want to move it inside.

    Fiberglass is fun. Here are some pics of a box we built for an escalade when I use to build show trucks. Just something to keep your mind creative. It took two of us a week to build though. Looking back I miss doing it for a living, but the chemicals get to you after awhile. If you have questions about building custom enclosures let me know. A fiberglass box gets pricey versus wood, but it allows you much more creativity.
