SPL & SQ / Fabrication

This guy is nuts. Many of you have probably already seen this but it was my first time coming across it... Dodge Sprinter

I have plenty of room for my overall volume, but fitting 3 10's and a port on the face is my challenge. I am going to have a box of around 3.25-3.75 ft^3 tuned to around 35. I was going for around 60 in^2 port area, my inside dimension is going to be 30.5 so that leaves me with a port that is 2" tall by 30.5" wide. Ive already done the math and have the depth on the box to easily fit the port length, but is there any reasons against a port of this shape? I thought about using about 4-5 4 inch round ports, which is either 48 or 60 in^2, but with either route I need to have ports longer than will fit inside the box, and I will not run an exterior port because this is my dai…

Alright, so on my quest to get louder out of my trunk, I'm trying to really understand enclosure designs, and how different enclosure sizes effect response, output and other factors. Now I know the general basics, larger enclosures will be more efficient, smaller enclosures less efficient. But I guess I'm looking for some more in-depth information.

Hey guys, I have been into car audio for about 5 years now and I believe I am fully ready to to do what I would consider a high end setup. I currently have a 2002 Hyundai XG350L with my 2 mtx 4500's, alpine amp, and rockford fosgate p1 components and 2 ways in the rear deck, with a P300.2 powering them. I am getting ready to move into my parents new house within the next month and will have a full size garage to work in. This will give me the place to let my mind expand and come up with ideas. I have been looking around at some new subs, I Have a couple of ideas in mind but am open to any suggestions as I havn't heard any system bigger then 2 cvx's on a JL 1000. I a…

I have a non wall box for a 21 warden going in a 2 door blazer, I have two boxes saved as a design right now. Both are about 8cu after all displacements and have 120-130sq in of port. The box is set up for sub up port back. My question is, would having the port on the side vertically facing the hatch make any much difference then if the port was on the bottom running length wise horizontally facing the hatch. I know each vehicle is diff and theres no telling whats better, but figured maybe the way the air moved would be diff or somthing. Thanks for any help

I found a sweet deal I just picked up a killer old school soundstream Rubicon 1002. The blue one. It does 250x2@4 underrated, and 1000x1 at 4 ohm and 2. Will be PLENTY of power for the old front stage. And just a all around sweet amp And I've seen them sell for $250+. I got it for $85... nice...

Hi everyone, My name is Paul Mocan, and i am from Cluj-Napoca, Romania. Adrian_D is a good friend of mine, and one day we decided to transform my 20 year old Volvo 340, in a SPL car... here is what happend. We started with adding a second battery behind the passanger seet, and complettly removed the rear seats. We made a box design with 2 ports, one for SPL and one for music. My car was a wreck. I had oil and watter dripping out of it, but it was a crowd gatherer. I'll come back with some pictures...

think this is a good stasrt for a moderate sq set up i have a kenwood 6019 indash focal 165 6.5 v2 pollyglass componants focal 6.5 pollyglass 2 way coax. kicker zx1000.1 kicker 350.4 an 2 re se 12's subs. im thinking of swaping amps out to something more powerful but is this a good start?

I would like to go with two jl audio 13 tw5 or two re audio sl12 http://www.audiojunkies.com/blog/646/res-n...nclosed-woofers http://mobile.jlaudio.com/products_subs_pa...php?page_id=245

I just purchased a SSA Xcon 10 and will be putting it in my 350z. My question is.. Would a premade enclosure from "Zenclosures.com" be fine for it? Heres the link to the enclosure http://www.zenclosures.com/Nissan-350Z-Subwoofer-Box-p/z110ar.htm Any input would be greatly appreciated! Kyle

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

Howdy SSA. Haven't been on here in forever. OK so I am looking to create an interchangeable port system for my box. Here is the layout of the box: (Feel free to steal the design) Playing around with my little box designing sheet, I thought about making a system where I can remove an appx 7 inch section of the port wall and insert some custom made plugs to lower the volume of the box. This would be just to switch things around. Now does anyone have an idea of how i can create a moveable port wall? I thought about a slide-in design (a hole cut in the top of the box that would let me slide the wall down in like a dam wall) or maybe a system of rails. I'm just looking for so…

I am working on my plans for my box and would it be acceptable to cut a hole for a round port and have the port extrude from the box some distance? The Box is 3.5 cubes or so tuning to i hope 32 Hz for a 15. Could it be outside to get more airspace?

I'm currently thinking about building a box for a 12 btl with both the sub and the port aimed into the cabin, sealing off the trunk from the cabin. I have looked at tons of boxes doing this but they all port on either the right or left side of the box. I often have 4 people in my car so this would mean the seats would have to remain up giving the port very little room to breath. My middle seat has an arm rest that comes down and my idea was to have the box port right there so that i can just put the arm rest down and give the port a place to breath. My question is can i port the box in the middle and place the sub to either the right or left of the port. I don't have a i…

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 will not be competing in SPL contests, i just want LOUD bass (doesnt every basshead). The sub i will be getting is a Fi BTL either a 12 or 15, unknown due to money, I think a ported box would be the best, but my buddy told me that bandpass boxes are better. He said a 6th order box would be good, i have no idea what a bandpass or 6th order box is. Are they louder for the daily user? As stated in title, the car i currnetly have is a 2006 Toyota 4Runner, in it, i have mids and highs by pioneer, and they sound good.

My guages in my car are digital LCD. They are a teal color now and I'd like to change them to green. Can this be accomplished?

subs: 3 12" hx2 do i need 4" or 6" ports? tuning suggestions also welcome...i was thinking 6 ft^3 @ 34 hz

well i got the expo to wang finally. its go the 4 PG 15's and about 3 grand in watts for the subs and the windshield wipers are now jumpin off the window and it feels liek your in a wind tunnel. I smile every time i get in it and blow my ear drums out with it. what? huh ? what??? dude i cant hear you speak up. Slayer sounds really good in it too. but i gotta love jammin some ying yang too. it will be at the march 27th import life tour at COBO hall in detroit. so if you can, be sure you guys get out there to check it out. Its ugly but it wangs. Im working on the fiberglass install still the guy that was going to do it went out of business. so theres a new cat gonna make…

i just went to my first sq event this weekend and the advice i was given by the judge is to try and widen the soundstage a bit along with getting the image a little higher. i sorta noticed this before but not really so brushed it off but after listening again post judging i could definitely see where he's coming from. he said its slightly above the a pillars and slightly wider then the car but needs just a little more. I listened to hotel cali again along with some michael jackson on the way home and noticed this 100%. any advice on how i would do that? Pointing my drivers side tweeter up helped a lil bit on some songs but I'm pretty sure I'm lacking some midrange up high…

Birch is looking a lot better than MDF atleast in Miami humidity for a 2002 Chevy Avalanche midgate enclosure. But I need help on the best specs to get the most out of 2 Nightshade 15's sub box. I'm going to coat it with spray on Truck bed liner to protect it. Sundown recommends a 2^3 enclosure but I just wanted any tips and the best layout that's worked for you all.

ok heres the deal. i my box is sub and port same direction as of now i have them firing port up sub up. and there is around 4 inchs space before the trunk lid, and i am scoring a 148. i think i maybe able to squeeze the box in sub back port back.. but i will only have 2 or 3 inchs between the subs and port and wall of my trunk. if i change it up now.. and lose my score then im fucked for this weekend. i have talked with another town car SPL guy. and he stated, in all his testing center port back. he lost 3 DB. from having port on one side, and lost .5 db's on the dash (meca) with sub up port up i guess my short question is.. and at this point its just a g…

any one with a 2.2-3.0 cu./ft speaker enclosure for sale. it is needed to house a single 12" bl tuned to 32 hz. o fit in trunk of 2006 ford focus zx4. also if no on that then i need a box for two 12's for trunk of same car with same speakers 12" bl fi loaded.......G

due to the complexity of the sides of my box, its going to be kind of hard to build a slot port on the top of the box. i was thinking, instead of a slot port, should i do like 4 6" aero's? (or whatever i need to get the right amount of port area) which leads me to my questions. -if you have 200 (example) sq in of port area, with a slot port, if you switch to aeros, do you still need a ton of aero's to get 200 sq in? or does less aeros equal out to the larger port area of a slot port? -aero ports in a wall. how will this work? i know one con is i dont get the natural bracing a slot port would provide, but ill deal with that, and add some extra bracing. -difference in sound…
