SPL & SQ / Fabrication

I have never done a wall before, and i am really interested in them. If its not too much trouble i was wondering if i could get schooled on them -- how to prep a truck for a wall, the do's and dont's, bracing, etc. etc. etc. I would like to become confident before going balls deep into this build and I don't want to be slapped in the face by how little i know half way into the build, ALSO i want to know what i am getting myself into before i start cutting. (ported, 10-20 cubes) i seen the build a wall build and it had a SHIT load of 2x4s.. would i have to do this to my truck? The truck will be a 1986 GMC Sonoma (S15) ext cab and the equipment is 2 or 3 (depending on how …

Crazy, stupid, or cool? Thinking about doing wall with 2 18's. Not for spl, just daily pounding.

I have a number of questions that I was hoping someone with experience can answer. I'm currently running a 15" BTL off 1600 in a 4 cube enclosure at 33hz. I feel like I don't have enough port area- i'm using one 6" aero which gives me 28" of port and 7" per cube. Do you think i'd have a noticeable difference by switching to a larger 8" port? I already bought the port, but don't want to destoy my old box if there wont' even be a noticeable difference. I'm hoping to achieve better lows...I figure that my larger port will give more output/peak at my tuning frequency of 33hz, hence giving me a better low end. In doing so, i'll also gain slightly more volume in my box (…

if you got a question just ask more than happy to help and if i can't i find the answer for you

whaaaaaat. The wires in the terminals are a little cleaner now, had to adjust them some. But they are bad ass custom brass terminals. no ring terminals! see ya at finals...

Has anyone ever had 2 boxes or separate chambers with 2 different tuning frequencies? ie. 2 subs, 1 box/chamber @ 26hz other @34hz. If so, can you explain your thoughts on how well it worked or didnt work for you. I was thinking about this option, but I am beginner enough to not consider all of the pros and cons in depth. Thanks for the input.

I'm running an Fi BL 15 on a sundown sae-1200d in a scion tc. Bought a prefab box for it a couple of months ago but im looking to get my system as loud as possible (currently upgrading electrical as well). The box seems to be tuned around maybe 50hz or so, as in Young jeezy's song "white girl" (i believe it has a 30hz note and a 50hz note) and the 50hz one hits way harder than the 30. If i built a new box, and tuned it to around 33hz, in that song it would be the other way around having the 30hz note be the louder one correct? Heres the box that I have now: http://img841.imageshack.us/img841/1833/img2746u.jpg How much would it cost roughly to build a new box like this (s…

I am going to my 2nd comp. this weekend---state finals of WV---I will be competing in the Stock SQ class and I am nervous hoping I do well---I think I have tuned my car so much it is starting to sound unnatural---I need to leave well enough alone but if anyone here knows me knows I can't leave anything as is.----sorry I had to rant alittle.

who's going, and JW why registration is free? Who's putting up trophie money? Keep me posted. Sounds interesting

hey guys, im having a hard time deciding on which box to build for my 18" nightshade. i will be using a hifonics brutus bxi1610d amplifier. i have a fairly small trunk but the sub will fit with a correctly sized box. i used the re calculator to come up with 2 different designs. i need your help to choose which would be best. here is the first one http://i903.photobucket.com/albums/ac235/thebiggmann12/2.png and the second one is here http://i903.photobucket.com/albums/ac235/thebiggmann12/Untitled.png the one with the port along the bottom would be port back sup up and the other one would be port up sub up. it will be going in a hatchback focus. if u need any more informati…

Hi I recently had a box built by someone and I want to make sure the tuning is right The ports should be tuned to 33hz The box is for (2) digital designs 2500 12" It is a dual 12 box, sub + port firing foward 34W X 14H X 24D outer dimensions 2 ports come together in the middle and are fully seperated til an inch from the front the 2 chambers are completely seperated down the middle an outer dimension: the port walls on both sides are 18 inches long into the box inner dimensions the port height 12.5 port width: 1.75-2inches (starts at 1.75 at top, slanted to 2inches by the bottom) I hope this isnt too confusing I can try 2 take pics if needed but id have 2 fi…

Here is the quick rundown: 4 Soundqubed HDS300 FS 33.65 hz QMS 6.912 QES .769 QTS .692 VAS .782 Ft3 Outside dimmensions of box: 16.3"x41"x27" = 10.44 all setup in a common chamber Port size: 8"x40"x65.88" @ 30 hz I believe this is all correct but what a double check before I build this box. Thanks

just wondering how to find out what frequency to tune a box to? do you base it off fs?

Okay, Elderado told me that in my car, i have a gas tank between the trunk and the back seat. I actually think that the tank wall is my trunk wall. Anyways, Odds are good that I cant get wire back through any cracks there.. So, where do I put it? <pics tomorrow when its daylight> So, I was thinking maybe right behind the drivers seat in a nice sealed box with some plexy glass over the top so it doesnt get stepped on. Either that *not behind the passenger seat becaues its always moved* or I can stick it in the rear deck. Like, I could be able to drop it inbetween the two rear speakers? But I would need to check the space between the deck and the gas tank. Als find ou…

Me and smokedog will be hosting a show in bluefield wv at an autozone. We will have it at the end of sept. To space it out from the other shows thats happening up here so we dont get burnt out on it. Spl will have 5 classes still and we are gonna do sq as well. Door prizes will be supplied by Autozone, it should be a blast. But spl and sq will be happening at this show.

After i told him my system he txted me two days later telling me he got a new system he said he got four dual 2 ohm 12s running off a 1400 watt rms amp and he says the box he has is 1.4 cubic feet per sub sealed but he said its tuned to 40 hertz. You cant tune a sealed box cam you? and anothr reason i dont believe him is he drives a pt cruiser and when i asked he said he still has his back seat in. Could u even fit an almost 6 cube box in that timy a** storage compartment? Thanks for all replies

Wassup y'all, I'm about to start a box for a 21 in death penalty. I'm going for 9 cubes at 30hz with 3 8in aero ports which equals 150in of port area. Is that too much? I've heard the sub will not handle much power? Someone help me out haha

Im going to be building a sealed trunk enclosure. I have a Zv4 15 that will be firing forwards. The amp will be a BE.2500. I need some advice on how big the box should be. My max dimensions are 15.5 tall 42 wide and 36 deep. I would like to use an aero port instead of a slot port. How wide and long should the aero port be if i wanted the tuning frequency to be at 30 hz? Also, if im going with an aero port, does that mean the box size doesnt have to be as big to accommodate the slot port? To get the 68 in^2 port area would i need to have two aero's or could i get away with just one? Any help is appreciated.

I've decided to build a box for my 15" SSD that will fit in my trunk. I was wondering if these numbers sound right or what it really should be. Lol Box will be 28" wide, 17" tall, and 22" deep. Port is 3.5" wide and 21 inches long. Looking to be around 4cuft tuned around 31- 33hz Does this sound right?? If not help is very appreciated!

Is there anything I should look at when deciding where to put the port? Middle port, top port, driver side port or whatever. . . It is a b-pillar flat wall with 2 zcon 18s on 5k plus at first

after a little debate.. well not too much I've decided this has to be asked on this forum not ROE, where most consider SQ to be 2 pair of loud Pa speakers with no tweets I'll be running a set of tc 3hp motors w/ fi top ends.. dare I say Sealed, over there If I mentioned sealed I'd be crucified But on to the front stage. I have a alpine 7949 deck, and a sony xm5046(mobile es) so plenty of power for a nice front stage. First time running active. I usually run passive comp sets, which I have liked, but want to try my hand at active and see the differecne. I was considering a set of seas excels, with a lpg tweeter. What would you suggest that would sound as good and …

I know you have to put slits in the wood, but how do you know how deep and so on, is there some type of formula? I know i read it on here some where, but i just cant find it.... Thanks,
