SPL & SQ / Fabrication

I'm going to be building a box for my friends Ram. Aero ports seem to be the only way to port this box but I've never used them before so im looking for a little help. Box will be going under the rear seat. The sub is a JL 10v3v3 Box will be about 1.33ft after sub displacement Tricky thing is I only have about 3 inches of height for the areo.(Rectangle box with wells on the bottom) The Rectangle part of the box will be W54.5-D13.5-H3 JL Recommends 32Hz 84.7 Slot Port Area

I have two alpine type r 12's and i want to build a crx-style box for them. This is the design i came up with using the max dimensions i can inside my vehicle. I really can't seem to get the tuning quite right, and it says its about 30hz, but what is the ideal frequency to tune to for daily driving? Also any helpful hints to getting this box to stay together? I blew the port off the screws in my bandpass like two weeks ago. EDIT: And yes the subs are going to go on the top.

with making my box for four 15 subs sounds great but i have a slot port at bottom of the box and when the bass hits hard the middle inside of box flexs and makes a vibe sound. how should i brace this with out change the tune of the box?

seen it a couple of times during my visits to select products site. anyone try this stuff? i am trying to get a better idea of the result i would get with it. my car has this felty suede material in the center console and ashtray area. is it similar to that? i was thinking of using it to line the bottom of the amp rack and wanted to know if it is decent or i should just do real suede?

I need a sheet of hard plastic like ABS to use in a bunch of places in my car. Does anybody know where to get anything close to that? I haven't really done any research so if anybody could point me in the right direction I would really appreciate it.

I have a F250 Crew Cab and have 3 JL old 10w6s powered by a Diamond Audio D61000.1. They are in a 52" long box ported to 33hz. I want to get a 10" Fi BL and 1) wanted to know if this will hit harder that the JLs and 2) the box recommended for the BL is 1.5cubes, could I make a bigger box for the 10?

So I have two 21" dp's and I am wondering, what is a good rule of thumb for port area on a spl box? As far as square inches per cubic ft? I have never done a spl setup. And I am planing on doing two slot ports for spl and plugging one for daily use. And would 10 square inches per cube too small for daily beating? Also may try something like four areos to keep down on internal space.

Ok guys ive been looking at some system setups and i found what im wanting to go with. Im looking at ordering 2 BL 10" subwoofers, well want im wanting to do is my truck currently has a bench sit and i was going to get to bucket seats and build a box/center console bewteen the seat and what i was wanting to know if the 10" will work in that spot and still have enough air space to beat down im trying not tunnel my truck because it is going to be bagged and not sure where im putting every where yet. I have a 90 Toyota Pickup Single Cab so if u can let me know that would be great. Here is a pic of a sample of want im waning to go with. The speakers in this truck are 8" spea…

So I'm good at building enclosures.....calculating ported enclosures? Not so much. I've just bought a new tow vehicle and using some budget equipment to put a nice setup in it. These are new items I've had laying around to put into a project car I'm building that won't be finished for a while. Vehicle : 2004 Escalade ESV (Suburban sized one) Location in the vehicle: Rear hatch, against the 3rd row. Want to keep some cargo room Space available (Length x Width x Height): 46" wide is set. 16" deep is set. The height is my variable. 20" is maximum. All dimensions are internal. Subwoofer make and model: Subwoofers are JBL GTO 4 ohm models Subwoofer Size: 12" …

I got everything ready to cut untill I forgot... What tall is the mayhem 12". I have it ordered but don't have it yet. On site says mounting depth of 7.75 inches. I don't know what that means.. Help pleaseeee

I got a cut sheet from skar audio, and i want to know others opinions on it. Ive tried to draw it up on paper to visualize, and ive done some calculations to help someone who knows how to use the info. Its for a friend so i don't wanna waste his cash on a shit design. Ok so he has a 97 Jeep grand cherokee. 90a alternator, I did the big 3 for him in some 4 gauge stinger pro i had laying around, and he had already bought a Rockford amp kit 4 gauge also...pretty nice wire. Ok the max dims are 36" wide, 36"deep and 30"tall, this leaves plenty space for the port to breath either up our back..The subwoofer is a skar audio ivx15 V1. Its a d2 coil. Here's spec off woofersetc.co…

Hi guys, I'm about to start on my first build. I've got a temp. sub that has been laying around for a while that I want to use until i get some money saved up to rebuild. It's a sonly Xplod 12 (I know) it'll be running off a rockford fosgate 300.1 in a trunk. I'd like to have the tuning somewhere around 28hz-32hz.. I'm not sure how the driver will like it so i'll let you guys tell me what ya'll think. It'll be going in a 2002 Buick Regal trunk. The demensions are: W=45", L=45", H=21.5". Those are the max demensions. If you guys need any more information just feel free to ask. The subwoofer model is: XS-L120P5W

Alrighty then. So im trying to decide whether to wall off my new system or having port back subs up. What do you guys think would be louder. The dimensions i am working with are. Length 53 , Width 49, Height 47. The system i plan on doing is two Fi BL 18s with two Sundown SAZ-1500d. Thanks, Kasey

ok so i cant read a tape for nothing so i got the guy across the street to read it for me on my box iv'e asked this questions a few times but never had the right messurement's but now i do here they are the depth is 22'5/8 the lenght is 41'1/8 the width is 22'13/16 i have two L shape ports the messurement are length 4'3/4 depth is 18'1/4 and the bottom of the L sape port which gose toward the center of the box is 10'1/2 remember i have two L shape ports one on each side of the box with the same messurement's now at the bottom of the L shape port where it goes toward the center of the box i have 5'1/2 from the L SHAPE PORT to the back of the speaker box these are all …

This may come out the most newb question on earth. When running multiple woofers, do you need a amp that is ratted to power the RMS of each woofer or both woofers? In my case, for 2 btls, to run both off one amp do I need a 4,000RMS amp or a 2,000RMS amp? or should I just be looking at individual amps like strapping 2 sundown 1500s together? I've been looking at the sundowns and the rockford 2000 and 4000 amps.

i have a box with 4.4 cubes after sub. it has 2 4"x12" ports can some one tell me what it is tuned to please

Alright, so i'm building a box for my 15" Q My problem is the max hieght i can get out of my trunk is 16". My question is that my front plate after being cut out for the sub only leaves 3/16" on each side. Being that the front plate is 14.5" tall. Will it be enough to support the sub itself or will this rob its structural integrity? I would like to advoid slanting or angling the front plate to fit it in.

K, box dimensions are 35x32x16 externally. Internally this gives me roughly 8.57Cubes. I want to port this to 34hz or so, and i need a min area of 6 cubic feet after displacements, is this possible? I also need to know how many sq inches of port i should need. I am just going to run out and grab 2 sheets of MDF right now so any help would be wonderful. The only confusing part is that the RE calculator keeps giving me ridiculous port lengths when removing the second portion of the L to make it a square. Any port dimension recommendations would be wonderful. Thanks in advance. Chris

it didnt hit me how big it was until i started cutting the pieces, seriusly, its like a mini dog house... I gotta go buy another sheet of mdf, dam thats 44bux...22$ each I have my friends lil d-snap camera, but he didnt giv me the usb connector to get the pics off of the camera hopefully i'll get it 2ma.. and hopefully i'll be finished wt the box by then also. now i still gotta order the subs

Anyone know if there are any major/non major SPL competitions in NJ area. I would like to go up and watch and maybe participate in the future. But mostly just watch in awe. Curt

Well I need to know what size recones to order and box to start building.... will either be doing 2 12" zcons in a 6th order ported through rear deck or 2 15" zcons in ported firing into car with trunk sealed off. . Really wanting to be over 150 db's but not just wanting numbers. Wanting crazy daily driver. Did a 145.6 with one zcon 15 on 3000 watts so hoping I can brake 150 .......either 12s or 15s will have same amp. Thinking bc5500 or somewhere in the 5-6k range. Just wanting peoples opinion on which I should go with. Cause wanting to order asap so I can have them before summer

i got 2 15 fi q i got a subwoofer box with the front slanted.. will it make a difference in sound?? i got 2.3cubic feet per sub on the box.. on a 2005 nissan altima running a soundstream rubicon 2500 with kinetik hc600 and rockford fosgate 0 gauge amp kit.. the box is on its way and im worried about will the slant make a sound difference will it decrease the sound quality?? ill be facing the subs towards the trunk away from me. well its in the building process..i can send an email and tell the builder to make it square if it makes a difference..

I designed Shogen a box, I just want him to see what it should look like when he's done. And I SUCK at Sketch Up. Who's good?

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 …
