SPL & SQ / Fabrication

I am building a wall and still need to seal it off on the sides and wherever there is space in between the box and the car walls. Is there a cheaper more efficient method besides spray foam? I am asking this because I am going to need about 20 cans of spray foam, if not more. I have also heard that spray foam is hard to work with. If there is something that is about the same price but is easier to work with please let me know. Thanks!!!!

I just finished my box for my fi btl and now I'm looking for something to cover it but not sure what yet. I've looked at CF and Carpet together (having the entire box black carpet with the fi bomb sticker as a cutout with CF over top) and thought about bed liner but I've never tired either and I'm not sue what would be the best look and if there are any more ideas out there throw them at me in open to anything.

I have some final questions for my box build. I wanted to use two 8" aero ports that i was going to run through the rear deck to the box. Both ports will have to be 32 inches long which is two long. If i switch to two 6" will that be enough port area for two z 15's? I need to switch to a smaller diameter ports so they will be shorter. What are the pros/cons of doing this?

For the Crown Vic.Town Car 4.6 Now the Exp.Navi 5.4 Im a bit confused on what they did exactly. maybe someone can explain it better. says its from an 08 navi, but alot the bolts should be the same.

Well thaks to McVay in Oswego we finally have some "local" shows scheduled for the 2005 competition season for IASCA. The first show is on March 27th, with one show a month all the way up to the month of October. I don't know about the rest of you guys but since I was unable to accrue enough points towards Finals last season, I just can't wait to get back into the lanes this season.

well, after a long and horrid search for a sub, i finally purchased a near new eD 13Ov.2 (bought in Jan. '06). now, its time to design an enclosure. i know eD has 1 ft^3 for the recommended but i was just curious if there was anything better, as it shows 1 ft^3 for the Ov.2 and Kv.2. obviously, looking for sealed right now, not going ported YET. i want it to hit hard, hit all those double bass kick drums hard, want to get as low as possible, and decently loud. oh yea, going to be putting 400 watts @ 4 ohms to it. no plans for amp expansion right now. im looking for a cube, not a rectangle as well. i figured up on rockfordfosgate.com and a 13.75x13.75x13.75 cube (external)…

So, it's getting near that time of the year.... I'm trying to figure just how I'm going to make it to finals this year... check out the sights, installs, and meet a few names. What better time then World Finals? So, dBDrag Finals are Oct 7-9 in Cleveland, OH. I'm definately going to be able to make it here, it's only a 3 hour drive for me. Meet shane, tottie, nick, loyd, tom, pete, iggy, and so on. Anyone else going? So, Usaci Finals are in Kansas City, MO Oct 15 & 16th. I'm going to try to make it down there, as I can get flights for ~$250 so far. Meet Matt, Mike, Justin, so on. Anyone else going? -Nick

pics of sundays show... more pics to come as they are e-mailed to me

Alrighty soo I've been wanting to do my own custom install for a while now. I wanted to acheive a more compact design- one that didnt take up much trunk space, was easy to remove if needed and that was still loud enough and cool looking to not only make me happy, but impress my friends too. Thus came the idea of the sono tube! With the design concept settled, I started looking for the perfect sub to make all the magic happen. I wanted something beefy, but in a 10". After some research, I ended up going with tcsounds oem tc10 and their matchin passive radiator (which might I add is one sexy little thing!!). http://www.mp3car.com/vbulletin/attachment...uild-d-cone.jpg http…

What I want for my doors is beyond my fabrication capabilities, so I'm considering looking for a fabricator in the chicagoland area to do them up for me. I was hoping you guys could give me an idea of what to expect it to cost, as well as throw me some names of reputable shops. I'm going to have them put 12's in my doors. I'm going to try a two way with the Dayton AMT-Pro's. I'm not opposed to working with someone from the board either! I sent a few emails to places I found on Google, but not many reviews to be seen. Thanks guys.

What are some easy ways you guys have used to gain DB's. Like myself, I found my old camaro did a few tenths better, with the hatch cracked, and the windows cracked, and the glove box open. Just curious what you guys have tried to gain those few tenths.

So I have heard to get optimum spl out of my box and best proforance out of my sub I would have to find the resonant frequency of my car. So I fired up the SSA forum seachers and i didn't come across so I imediatly fired up the google machine and did some seaching and here is my findings: I can use math by: Now you measure the distance from the cone to the meter(the whole path it takes). remember the soundwave comes out of the front of the cone at 90 degress(straight) and out the back at 180. once you get the distance from the cone to the meter placement in inches, you divide that into 13,560. you will probobly get a high number, which is suspected. Since its 90 degrees, …

Okay, I will be finished up my box tonight and had a few questions before I close it all up and get it hooked up. *I've seen online that it says to put weatherstripping around the hole for the sub before putting the sub in the box? This true? *And I've seen people use resin on the inside or their boxes to help the structure? This true aswell? Thanks for the help and thanks to everyone that has helped throughout my first build!!

I was messin around and just seein where the power wire would go through, and i realized that the firewall already in use for the factory wires was pretty much full, and i don't see how 1/0 is going to squeeze in there. But a couple inches to the right and one or two inches above it, theres what i'm guessing is an unused firewall hole. Its a rubber surround with a rubber filling. I tried to see where it came out on the engine side, and i couldn't find it. Does anyone know if i could (once i find the hole, as it was a little dark when i did this) puncture the rubber filling and take it through there? If not, what should i do?

I need advice on where to face my subs. my current box only fits one way. facing back, it is in a 1996 geo metro and was wondering us anyone had experience with subs back in the hatch. Thank you very much

I drive an Olds Bravada (basically a blazer) and I drive it daily, but its a weekend warrior for spl. I have an AA Havoc 15, I'm building the box to the SSA Icon enclosure specs, and running it off a MB Quart Discus 1500. Which would sound better/get louder, facing the sub and port up, or sub and port back? If I face the sub up I can actually use some of my cargo area.. but that isn't a big necessity. It is a four door if that matters.

Saw it on a few different threads over the interwebs. Alan Hall did a 160.2 at a 3x usaci meet. He's running two 15" Tantric HDD's and two RD D9 amplifiers. Damn Great score.

So going from my current setup to something more extravagant should spark your interest. Wanting to go with (4) SA-8 V.2's in a 4th order box with a 2:1 ratio. From what ive gathered so far on reading.. * Speakers facing sealed chamber(better cooling&so you can smell the coils if needed) * 15^3 inches of port area PER cubic feet of sealed chamber * The shorter the port the better * Ported chamber tuned to around 45-50 hz. Here is what ive come up with on Sketchup so far. Sketch is not to scale. Came up with - 2.6^3 feet in ported chamber and... - 1.3^3 feet in sealed chamber. Would love some input or constructive criticism/ advice an…

I need help with designing an aero port enclosure. This is my first attempt. I am looking for 2.5 net and tuning 32hz, With corner bracing. I would appreciate all help I can get! Thanks.

Hey everyone, So ive desided to build my first sub box and am pretty much lost. I have 2 10" Alpine type-s subs being powered by a MRP-M500 alpine mono-block. At the moment i have them in a pre-fabbed folded horn box and just want an upgrade. On the Alpine site, they list the"optimum" vented box's stats which are tuned to about 36hz, which sounds good to me. So..... Would it work if i built 2 seperate boxes that share a single wall seperating the two? If i did that would I run one vent for each side and keep all the stats for each box to alpine's site? Ok, this question is confusing me just thinking about it so if it doesnt mak…

Will be built in car in this area. Slot port on drivers side, sub and port firing into cab, sealed off from trunk. This is what I've come up with, but how do I figure the 90 for the length of L port? Thanks in advance.

So I'm taking my setup to a 1x event in timmonsville sc. I'll finally be getting metered on a t/l, but I'm wondering what I should bring with me, and if anyone has any tips. There are 2 classes they said I could compete in, truck/suv or something else like extreme personal or something like that. I don't know what would be better, or if it makes much of a difference because like I said, it's my first competition. I've already been told not to do anything to drain the batteries before getting metered, don't know how sound that is or not... Just wondering if there's anything I should know before driving 70+ miles away tomarrow moring. ;D Thanks.

I'm designing a box for a 10" sub to go behind the seat of my 1988 toyota pickup extended cab. I have an air compressor behind the drivers seat and I don't want to lose access to my jack and tools behind the passenger seat. The floor is uneven so it takes up a lot of volume. Here are pics of the area i have to work with. And here is a basic design i made on sketchup It is 1.66 cu ft before sub displacement and port. I'm looking at an fi ssd sub and a 1000w rms amp, but I'm open to other suggestions. The sub will be facing the front. I have a formula for tuning a port and I'll probably do a slot style port but I'm not sure where in the box to put the port or how much …

I have an audiopulse axis 15 and a saz3000. I finally got my non-blown sub in the box and in the car. I was tunin it all and saw my hair movin it the window, so i got my gf to come over for a try at a hair trick. enjoy

sup planning on entering in my first spl comp. in Roanoke Va. Mar.22. Was reading the rules and got somewhat stuck on the part about the fuse requirements. I'm using a 200amp circuit breaker, do i need to install a fuse in its place to enter. Will be running a saz-1500d on 2 12" lvl4 d1, also would be considered AS1 or AS2. Hope to meet some of you there. Styllikeitloud
