SPL & SQ / Fabrication

I have an RE Audio SX 18. I've heard rumors that this sub can do 2,000 watts RMS fairly easily in the right box. I currently have about 500 watts going to this sub in a 10ft^3 box tuned at around 30 Hz. It's pretty loud. I got pulled over a few days ago for having my music too loud and the officer said "Dude, you were shaking my car, what do you have back there?" Got off without a ticket . I wanted to step it up a notch so I just ordered a Hifonics Brutus BRZ1700.1D. Which does 1700 RMS @ 1 ohm. I designed a box with a net volume of 7.19ft^3 tuned to exactly 34 Hz. Sub up, port back. (My old box was sub back, port back.) For the record, this is going in a 2006 Expedition.…

Hi, I was wondering if anyone has made or heard a sub placed between the front seats. I have a venture mini van. I can have about 1cf of space to work with (id). If you have done this or heard a setup like this please let me know what you thought. Thanks, Duane

I have a Dodge Journey that I want to put 2 SX 12s in. (By the way, only have one right now, need another. Put the word out, D2) I want to have the 'right' box for it. Not one that a experienced builder can demo and know quickly that it's a crap build. I have been reading the available threads on what makes a vented box a 'good' vented box. But to honest, it seems pretty complicated. I am not a fluid dynamics student. But I am trying to learn. It is hard to narrow down my music style. It's 50/50 between hard rock like Metallica and such, and also rap/hip-hop. I know that doesn't make it easy. It will be running on a solid 2300wrms. I have the whole back available for the …

Could anyone draw up a quick sketch for me? Car - Crown Victoria Subs - Obsidian 15s Amp - AP18001D Specs: W = 41" D ~ 21" H < 24" @30hz Daily box but going for SPL Subs up Hopefully someone can help me out

I've got a pair of Kicker comp CVT65's just laying around and I thought I should do something with them. the manual says 0.2^ft sealed and well.......that sucked. wondering if anyone on here has any experience with these in a ported enclosure or any other recommendation that might make them work.

Hey Guys, i'm sorta new to the forum so do bash me too hard I am designing an enclosure for a 21" Death Penalty. This is my 4th variation: 8.533^ft, Tuned to 33hz, Kerfed port opening, Double baffle, 1 1/2 Port bracing, 1" Dowel bracing, 121^in of Port. This is going in a 1996 Blazer, Port faced towards the hatch. I want it to as good as it can at being "musical", do you think it will sould all around good with this enclosure? Give me your opinions, thanks.

hey guys i have a box in my 2000 grand cherokee in which i had a single sa15 but now the sa15 is sold and i just bought a Zv2 15.. my box is 36.5w 14.5h 11.5d and the slot port is 3x12x19 so i know i need to make the port bigger im just not sure how big it has to be.. trying to tune it to 32 htz... any input would be wonderful thanks

Well, i didnt think this was going to end up happening but i actually saw an Fi BTL N2 18" For $400 in my city. I was previously going to get a 15" Fi Q or BL which was going to cost me $400 shipped anyways so i cant give up this opportunity. Now in the quest for less trunk rattle, i wanted to fire my subwoofers forward into the cabin, BUT i dont have foldable seats. OhJay gave me a good idea. Use external aeroports that go through the rear deck where the 6x9 speakers go. I thought it was a great idea, something a bit different. Now i was wondering if any of you could make it happen. Iv got probably 19 inches maximum of height, probably about 40 inches of width. I…

I was bored so I went & picked up 2 12s from a flea market this past weekend to experiment with. Made my first box throughout this week & tuned it to 32hz. If I wanted to tune it to 30hz would I add or cut off some wood to the end of the ports behind the subs? I can do the math but need a starting point. Also another separate question, would more port area equal a lower tuning or does it depend on the box?

Ok so Im putting 2 12" xcons in the trunk of my grand prix gxp max dimensions are 35"W opens to 55"W 15"H 40"D. I want it ported what do you guys think would be the best box type of port which direction and so on I wont be building it but I also want the best and the builder Im using can do it. It is not a comp car however I play my music loud everyday and I want to be heard

I have been approached by a customer with 4 Kicker Warhorses and 4 Kicker Solo X 18s. He is having me build a 1990 Astro van to be all out SPL. i am looking for any help in the matter of tips, tricks, pointers, etc on how to do this install. Lexan windows are already in plans. Concrete floor will be a must (how do i do this? how thick? what kind of concrete? just the cabin or all the way back?). Lowering roof (how should i do this? what should i use?). Custom Dash (what do i use? how should i construct it? what shape?). Center Counsel (should I build one? just leave it open space? what should I build it with? how should design be?). should i cover the wall floor roof dash…

Is it cheaper to buy my own MDF and make a box than having professionals at a audio store do it? I plan on having a SA-12 and a box Ported tuned to about 32hz with about 1.7 cubic ft of space. I have the measurements and such. I used the re audio box calculator. I can get help from my woodshop teacher and some friends but I'm curious if it's cheaper. Idk how much they charge at the audio store but I'm sure it's not cheap. And another thing how good is birch over MDF? I can get birch free but everyone tells me MDF sounds better. Build would be musical and everyday driver not spl. Thanks guys can't wait to hear from you all.

so im pretty new to going to competitions and competting my subs. i was just wondering if only one has any tips or tricks i could use to help gain dbs?? anything will help i just dont want to go in this competition that is coming up and not know something to help me.. i drive a two door tahoe i have 4 12's ppi pcx subs and i was wondering if i folded down my back seat and moved my subs closer to the front would that help (probably a dumd question but you never know until you ask)

Wassup everybody?! I am going to add another 18 in my gmc Sierra Ext cab and I am wondering what is the best port placement for this setup? Also they are aq hdc3 18's and it will be around a 13 or 14 cube box@ 30hz my goals are a daily ground pounder that's loud as all get out, I may start going to comps

I have a 95 caddi deville, and i would like help in building a ported SQ sub box for two Dcon 12D4's. they will be powerd by a RF power T500-1 dbcp 2010 model. My bass gets trapped in the trunk,so i cut two 4" round holes in the rear deck to let sound inside the car. will the 4" holes change the tuning of a ported box? All help welcom. thanks

There was a video I got linked with a dude talking about his SQ comp car that had liquid cooled subs and amps and a reservoir in the back?

Supp' SSA!! I am looking to build a higher tuned box for my 2 15" Fi Audio Q's. ( I know they are not made for spl) just for fun... I do 148.1db @ 45hz (30hz tunning) but looking to see what higher tunning will do. For some reason i always peak at 43-45 hz with diferent boxes/tunning and a friend also peaks at 45hz with diferent boxes on 2 12's. Is it the Tahoe's peak or something?. Both are 01/02 Chevy Tahoe's. If i tune a box to 43-45hz will it help because of what i peak at ? Thanks for the input.

posted by ohjay is he a hater or did he just get a shitty box Bah, you don't want the POS box that comes with them, you're better off with the prefab boxes. I have one that was built by Kevin and the baffle flops like a fish out of water with 175 watt rms subs.

hey guys, i need help making the design for a optimal sealed box for my 2 12's. http://www.soundsolutionsaudio.com/index.php/product-information/icon.html\ the problem i have is i have a rather small vehicle and the space the box has to sit in is 33" wide and 18" high but to get it in the tallest it can be is 16" if anyone could build me a diagram or point me in the right direction it would be a HUGE help. thanks in advance, zack

My original box was the one recommended from ssa and it sounded good but the wife wants more space in the trunk so I have to do something different. So I need a box with less depth preferably ported still and a little longer tuned to 32hz. I don't understand how to use the box calculators I have found. Heres what I have to work with as far as area: 32"long x 16"high x minimum depth of the sub which i'm unsure of. The sub is 6" deep so I'm guessing a 1/2" more than that is minimum Basically I just need a longer less deep box that will still sound good. I listen to mainly rap/hiphop and some d&b. Any help would be greatly appreciated.

Hi guys, I currently run a Fi BTL N2 12" on a Sundown saz 3000 amp. I have no problem with the electrical, even if I know I may not push all the watts this amp can deliver ! My box was designed by Bromo of Eclectic Design (or something like that) : 2.1 ft3 with a slot port (32 hz tuning) firing through the (driver) side. The sub is firing up. The box is well braced too. It sounds good, but I want more output ! I can have another box built easily, and I already own two 4" flared (on both ends) ports. Those ports are in a 3.2 ft3 box used for a Soundstream XXX 15", for now. But I can get it back fast. This box may be too big for the 12" btl. What do you think about it ? I n…

So I got a box off ebay. Omg yes I did it. I am looking at it. Fits well looks good it's solid but the inside shows a different story. My speaker cups have huge gapr around them where air can escape. The glue is not thick or sealing the box very well. No I am not building a new one. a few questions. 1= What would you use to reglue it from the inside?? 2= What would you cover the terminal holes with?? 3= what are you installing the speaker with??

the box specs 48w*40d*20h port is in the center 18.5h*14w*22d what would this tune to and is it to much port for this box.goals daily ground pounder. subs 4 15 db drive plt15wd 2500rms

I have a single ported kicker CVX 12" in a custom box which I built, IT sounds nice. It is powered by a kicker 750.1. The box is tuned to 34hz i believe and is 2.25 cubes. The audio is nice, a nice mix between power and quality, the way I like. But Im looking to go bigger which is difficult because I have a volvo. I came upon an AMAZING deal. I am getting TWO kicker L7's and a 1500.1 kicker amp. Each L7 requires 3.23 cubes ported I believe. THER IS NO ROOM FOR TWO PORTED IN MY TRUNCK. But each one only uses 2 cubes sealed. MY QUESTION IS: Would I get more sound (louder) with one CVX 12 ported @ 750w OR would I get more sound (louder) with two SEALED L7's @ 1500w? I KNOW s…
