    ill probably carpet it or sand it down and paint it flat black in the summer, too busy with college to give a damn on how it looks.. lol

    up next on the build:

    big 3 upgrade 0 gauge.

    pioneer TS- A series 6.5inch fronts and 6x9 rears

    possibly a new head unit

    soundproofing all 4 doors and trunk!

    new battery when the toyota factory one starts showing signs of age

    :D

    so this is the first ever woofer box that me and my friend assembled, it was a good learning experience, box dimensions were as follows

    12inch height

    30 inch width

    20 inch depth

    3.2 cubic feet

    port specs

    3.5inches width

    10.5inches height

    internal port length (21.75")

    giving me a tuning frequency of 36hz

    port area per foot = 15.91 inches2

    3/4 inch mdf used with wood glue on all joints with pilot-drilled wood screws. then silicone on the inside, Big credit to 412 CVX for helping me out on how to properly design this box :). and now the porn .

    sorry for the monster size pics :P , first phase just getting the panels all lined up for test fitment

    45eJm.jpg

    walls and port walls are in :)

    clamps in this pic are just holding the smaller port wall in place while screws are being drilled in to lock it in place , also woofer cutouts have been measured out so they are spaced apart nice and evenly!.

    woofer holes cut out, you can see the previous day we decided to put silicone on the joints a bit early :P,

    getting ready to put the final piece in!!!, terminal was screwed into place and siliconed, we had to use a dremel to shorten the screws we were using so it wouldnt go all the way through the mdf for the terminal cup.

    ALL DONE!!

    now i have to wait until tomorrow evening to put subs in and try my new box out!! :)

    btw this will be going in the trunk of a 2009 toyota yaris sedan.. lol

    powered by a mtx tc3001 mono d amp, both subs are SVC 4 ohm 10inch Kicker COMPs , wired for 2 ohms as the amp puts out 300watts RMS at 2 ohm

    cant wait to hear some slayer and arch enemy from this new box .

    tune to 36, keep about 12-14 inches per cubic foot of port area, make a box that's about 2.5-3 cubic foot net, look at the physical port length and model it in sketchup so the port keeps the same width throughout.

    download torres calculator in the subwoofers/enclosures section.

    download google sketcup (just search it)

    if you want a foundation on how to do everything, i've got a ton of pictures on my facebook page that you can reference.

    any links to websites where they explain port area/port length? i understand port area( dont understand how its calculated) , port length i dont understand either.

    damn if only you took EMT i would have already paid you to design me one :P

    going thru torres calculator now to try to figure this all out..

    1.9 cubes is about perfect for the power you're giving these.

    sweet, thanks for the advice, lets say i wanted to upgrade to the 10inch kicker compVR or VX in the future , would a 2.5 cubed sealed be enough? (for 2 of them). i wouldnt mind being able to reuse the box :) ( im on a budget, college student and whatnot. i was lucky to get these subs and amp for cheap anyway :P)

    ok so im going with the sealed box, why not give it a shot. heres how i plan on building the box as per kicker spec, from the Kicker Comp manual.

    1d3A1.jpg

    my main question is , i double checked the dimensions using torre's box tuning calculator and it gave me something different, torre's box tuning calculator says that front/back (A) panels should be in between the top/down( B ) panels like ( C ) is in the figure above. now i dont know how to build it, should i follow the figure above and build it like that or put the front/back (A) panels in between the top/down ( B ) panels. ???

    Depends on how big the sealed box is, but it's better to start from scratch when building a ported box. Best Buy is usually a terrible place to test out ported boxes cause prefab ported boxes are usually too small, and tuned too high cause the stupid mainstream car audio motto is "Sealed box = sq, ported = spl" which isn't true at all.

    dimensions of the box i want to build

    width 33 inches

    height 14 inches

    depth 20 inches

    cubic feet = 4.21549

    thats how big the new sealed box is supposed to be.

    truth be told i dont hear any rattling from my car.. (only some change in the cup holder lol, would it be hard to convert the box to a ported box after i build it as a sealed? , im gonna go to bestbuy/futureshop and try to listen to some metal on ported boxes and see how it sounds, if i really like it ill make a ported box tommorow using the dimensions i posted above. in the event that i do what freq should i tune it at and where should i put the slot on the box?.

    if i plan on getting better subs i will be upgrading amp as well, well ill give this box a shot, worst case scenario it will sound alot worse then the current one and ill switch em back out. and build a ported box, best case scenario it sounds exactly like i want it to and keep it. this is my first system ever so im a bit paranoid to push 500 watts rms to these subs. :( (i do still have receipt for purchase and the original boxes for em, i got these subs at a discounted price when i went to the local distributor, kicker said i bring in the old blown subs then i can get new ones of the same model for a discounted price.)

    well i kinda jumped the gun and had the mdf cut yesterday at home depot ( the guy was cool and didnt charge me anything for the cuts) so i spent about 38$ on the mdf, ill try to build it at the size i made and stuff it and see how it is..   the new dimensions  cant go any bigger due to trunk space limitations.  all i can do now is trim the panels so the box is smaller( i do have leftover mdf). and i havent heard my type of music on a ported enclosure so im worried about building a ported box.. :(

    yep, i will be pilot drilling holes for 2 inch long wood screws and using carpenters glue on the panels where they join, then for interior i will be using clear silicone on the corners ( will let it dry and air out for a few days before i put it to use.. i was under the assumption that if i wanted fast and tight bass ( especially for my death metal, a sealed box would be better?)

    here is an example of the type of music i listen to ... lol dont freak out :P

    greetings everyone, i currently have 2 10inch Kicker COMP subwoofers, 4ohm SVC 150watts RMS each, hooked up to a MTX TC3001 amp (i wired them in paralell so there would be a 2ohm load on the amp which outputs 300watts rms at 2ohm. i recieved the box and 2 old kicker comps ( one was blown) from my boss as a gift for helping him out with a job errand, the box is of alright quality ( put together using a nail gun, and theres a small hole for the speaker wire to run to the amp, it could have been built better). i listen only to heavy metal/thrash metal, death metal, black metal etc), so alot of double bass drums are put through these subs. below is what i want to do

    dimensions of the current box are as follows.

    width 29 inches

    height 11 inches

    depth 14.5 inche

    cubic feet : 1.96542

    dimensions of the box i want to build

    width 33 inches

    height 14 inches

    depth 20 inches

    cubic feet = 4.21549

    the old box has NO polyfil stuffing in it. the new box will be made of 3/4inch thick MDF, be properly sealed and have polyfil stuffing.

    The Goal of this whole project

    im not 100% satisfied with how my subwoofers sound when double bass drums are playing (sound a bit echoey/muddy), kicker recommeneds for a "compact" enclouse a minimum of 0.9 cubic feet per subwoofer, and 2.3 cubic feet for "maximum SQ " per subwoofer". I want the bass to not sound muddy and also hit hard, am i taking the right path building a new and bigger box, or should i make it smaller?, keep in mind i may replace the amp and subwoofers with better 10s such as the kicker compVR or compVX . So what should i do ? :)

    thanks for the help!
