Hey everyone. I'm starting my first build today and the dimensions of my box are going to be around 34w x 18h x 16deep. I wanted to have subs up and port along the bottom of the box facing the trunk (its a hatchback) and doing that would tune it to high. Am I able to put the port in the middle of the bottom or does the port have to be along the whole edge it is on? If it has to be along the whole edge I will probly put in vertically on the back side on either the left or right edge. Please help, this is urgent. I'm going to be starting it in a couple hours. Thanks, Ted

Well my set up starts as this the 18 inch xcon will be going in my rear seat of my 1993 ford mustang gt i already have a cheap 15 inch sub in the hatch (its on its way to being replaced just figuring out with what) so back seat is where the xcon goes Now i have enough space for almost optimal ported box but it cuts visability down a fair bit and this is a daily driver. So my questions are how much sound loss would i loose roughly going with a sealed build as to a ported build ( not really going for sq tho most know xcons sound amazing anways). 2nd ? if i do go ported is there a huge diffrence between going say 6ft^3 affter displacement and bracing as apposed to say 7+ft…

Hey guys..I haven't completely started building anything just yet and this will be my first build and was just wondering about the port type and location of it and the subs. I don't have any exact dimensions or anything just yet just need to get a simple idea first. I have 2 T12's (rockford) in a prefab box now and wanted to make an good box for them. Any idea's on port type, sub and port location would be appreciated. And any first time building tips! I've heard a lot about subs up and port back but not sure if anything else would sound better in a hatchback. Thank for the help in advance, Ted

Okay, so ive been trying to decide what i want to do with my 600 dollar tax return. i get it in a week. =) not bad for only working two months eh? lol anyways... I have a 96 tacoma regular cab pickup with the bench seat in it. I have had a few systems in it. I have a brutus bxi2008d. My PLAN is to get an SA 12 and build a box as big as can behind my seat. (after many measurements and few boxes that ive already built i think i can get about 2.3 cube inside of a 3/4 box before any displacements) with that said onto my questions... i have been using the12volts calculator for port length.... with from i have heard the general rule of thumb is 12-16 inches of port area per c…

Okay, have done some reading around, and from what I'm seeing is that guys are getting good results in x-cab s-dimes with an up-firing sub/ side firing port design. So, I'm thinking I might give this a try. vehicle: 03 chev s-10 subwoofer: RE Audio SEx 15 (dual 4 ohm coils) Amplifier: JBL GTO 601 (600 watts @ 2 ohms) Looking at doing an enclosure out of .75" MDF Outside measurements: 15" height * 40" width * 16" depth Slot port: 14.5" wide * 3" high (port area of 43.5") * 23.5" long (tuning ~33.5 Hz) Net enclosure volume: 3.6 ft^3 Big question I have is, will 43.5" of port area be enough, or do I need more to prevent terrible port noise? Thanks for your opinions in advanc…

Now that i'm playing the find-a-car game again, the beetle is back on my list, for price reasons. I currently have nothing planned (well i know i want thump, but beyond that, nothing) With a budget of $3k what is the loudest you could get a beetle, tuned low, to peak around 27-29hz. Back seats are optional. Would like a pair of subs, but a single badass sub wouldn't be the worst. everything besides the fabrication of the box, is done by my hand. This seems like a backwards goal, but my desired show off songs would be, like, Trunk Bang by dorrough and I cook - by OJ da Juiceman. If the low tuning doesn't murk the score, i'd like to be able to compete. Mid 140's would be a …

I saw this on a video and I want to know if its possible for me. Here is some info: I want to go with the musical ported measurements. 2.5^ft., 4" Vd, 13.5" Vl, tuned to 28htz I want the outside length to be 31" (including ports) max, I want it 14" high. What I don't know is the depth. I have a 3000 watt amp and listen to various kinds of music. If someone can help me on the dimensions and maybe even a plot of the spl curve, it would be greatly appreciated and I can get to building. Thank You. Edited to add, If I left anything out, please let me know so I can provide you with the info. Thanks

I have an old sub box that came with an RE SX15 I bought used. It is 3.1 cu ft net before driver displacement. It has 2-3" aero ports in it. 9" long. I used it before with the sx15 wired at 2 ohms on my saz-1500d. I never heard any port noise, but it didn't sound great. I later built a 4.25 net cu ft box for the RE tuned to 30 hz. It sounds great. Well I think I have a buyer for the RE and was wondering if an SA15 would work in the old box. It's about the right volume and tuning would be right about 35hz(recommended) but it's seriously low on port volume. I was also thinking I could put a third port in it for burps and bump tuning from 35-45hz. Not to mention increasing …

well i ran into an issue today, which isnt TOO bad just its one of those things that dont go as planned that you gotta get around well i was going to start a portion of my new build today, or at least test fit (thank god i test fit on this and didnt run into it last minute) but i had originally planned to fit my ID CTX65cs comps in my doors, the mids are 6.5" which generally i can fit that circumfrance, however.. not that specific depth i made these rings to go on the door panel, they are 3/4" MDF, with a 1/4" flush cut out for them.. flush is king and they fit in the rings like a charm (first time i made my own rings - so i was happy) i primered them and painted em so th…

as u can tell, no where to put subs under the seat. behind the seat, there is very very little space. The back seat is a 60/40 bench seat. that means one side is a seat and the middle seat, while the other seat is just 1 seat. lastly u can see that the console is not very wide, its not even 10" wide so cant even do a 10" sub there unless someone has an idea. only way i see console box working is if i downfire it, but it would be a tall box, as the sub cant mount between the seats, so it would be above the seats. so take a good 5" or more mounting depth sub, +the 4 inches to get over the seat+ 2-3 inches behind sub, it would be really tall. also behind the console, i tried…

I think I am moving from and L port to aero ports o I can get a little bit bigger box. I am trying to use this tool except I cant seem to get what I want. I am looking for about a 4.75 cuFt box (including displacement and bracing) with a depth no longer than 18 inches. I would like to get around 35hz for daily and 45-50 for competitions. Any suggestions? Help? The box is going to hopefully be 38w 17.5h and 18d which comes to a little more than 5cuFt and shuold be around 4.75 cuFt with displacement

Tomarrow I will build a new box for my new Xcon 12. I have two designs to pick from, one will be 2 cubes at 30hz and other will be 2.4 cubes at 30hz depending how much room I want to give up. (or anywhere in between I suppose) When I first got the Xcon, I put it in the box my Death Row was in. About 2.1 cubes at 31 hz, with 25^2 inches of port. There was definately some chuffing going on. My new box I want more port area. Max height of port will be 12.5 inches (14inch max height for box). Will either do 2.5 or 2.75 inch wide, for 31.25^2 in or 34.38^2in. Will either of these help with the port chuff I experienced with my old box? I know the bigger the better usually…

I am getting ready to build a nice simple sealed enclosure for my 12" Xcon. While im building this, I would like to go ahead and build an amp rack. I want something fairly simple. A false floor with the amps mounted down in the floor would look nice IMO but I need help as to how to start or what to do? this rack is for my 2000 Celica and the two amps are a Kicker 10ZX350.4 and a SAZ-1500. Pics or videos or just advice would be great!

Well, as some may know (from my thread in the subwoofer/speaker forum) I have an RE Audio seX 15D4 coming my way. So, I am in need of building an enclosure for it. So, this will be going in the back of a Chev S-10, and will be powered by a JBL 601.1 amp (receiving ~600 watts RMS) This will not be for competitions of any kind, however I do enjoy listening to music, as such I want something that has the ability to sound decent and yet still get fairly loud for just general driving around use. So, for dimensions, I can go up to 40.5" wide by 18" high by 14" deep (outside measures). I am looking to do a ported enclosure. Not decided on whether I should go slot port or roun…

Im BACK! After being gone for a while traveling the world I have come back to my fellow members / friends / people / dudes / dudettes and folks on the good 'ol ssa forums (good job Mark). I am starting a rebuild once again. I literally blew my old box apart so its time to go bigger, badder and more bracing! I noticed a huge improvement from my 3.5cuFt box to my 4.25cuFt box. I hope to do the same when I hit a 4.75 ish box. I am installing into this box a single DC 15" woofer being powered by a 3500D. Here is what my plan is: BOX: Height: 17.5in Width: 38in Depth: 18.5 CuFt: 5.083 Square Port Volume Internal: 1134 Square Port Volume Displacement: 1144.125 Tuning Freque…

Just purchased a couple of eclipse 88120s in a custom enclosure. I threw it in today and, similar to my hdc3, I am lacking in low end output. The box is dual chambered,tuned to 34 hz, and each driver has about 1.6 cubes. I thought that I did not need to build a new box because the tuning of 34 hz is low enough to achieve the lows Im looking for. However, like i previously stated, Im lacking low end output. It seems like Im never going to be able to get the flat response Im looking for. Thanks for the help guys! edit: The custom enclosure has two seperate ports, one for each driver. I could remove the divider between the two ports if that would help. But, as far as I know…
