SPL & SQ / Fabrication

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" …

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

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

Finally picked up a few sheets of MDF to play with to make my explorer box, what should the minimum port area be for 2 15inch RE SX's? So far i have messed around with the RE box tool and came up with a 6.1 Cube box tuned to 34.7hz with a port area of 74square inches. My available measurements seem to be 41 inches wide(before wheel well bumps), 18 inches deep, and i don't want to reach over 20 inches high on the height. If anyone can throw some suggestions at me for the area of port needed or maybe a box design they have used in their explorer it would be much appreciated. Thanks!

What numbers are you hitting with windows up, vs down? I need some numbers for this thing I'm doing. Thanks!

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 …

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…

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

I have a Soundstream Reference 500sx rated at 500 watts in 1ohm & 2ohm, is there a difference in sound quality in the different load and what about subs, does it make a difference in sound quality if you have a dual 1ohm or a dual 4ohm sub wired at 2ohm load are there any differences in sound quality.

just starting to figure these enclosures out a little. any one got any info.

ok so i want to make a box with 1 15 in the middle and 2 poorts, 1 on each side, to get it how i wanted it ported, could i just measure out the space i would need for 1 port and just put half of that on each side?

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

When doing a blowthrough setup in a pickup, will it really make a difference as to whether the truck is extended cab or standard?

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

hey whats up guys i have seen on the internet and on a few forums people using bedliner as a sound deadener does it work and has anyone had any good or bad experiences from it

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..

Ok whats the difference in one box tuned to 35hz with 2.5cuft and another box tuned to 35hz with 3cuft? also whats the best material to build a box out of?

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?

It's about 7.4 ft^3 with a 13x6.5" port. Two 12" type r's are going in and will be running at 1000wrms. EDIT: What would be best to tune this box at? I'm doing daily and want it to sound good, not just loud. EDIT 2: Listen to mainly rap.

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 …

well since i put in the 2 15" BL's on the sundown 3000d, i have NO windshield flex, a little roof flex which is no biggie, but the worst is the doors...the body panels are so thin and theres just a single support bar inside it, which flexs with it against the body panel. i put Great stuff foam and peel & seal. i know peel and seal isnt real deadener, but ive used it before and itll deaden sound for sure, maybe not as good but itll do the job. well it did hardly nothing. what would solve it is fill the whole door with expanding foam but that isnt an option, becuase i obviously need the windows to go up and down. any ideas? pics of my door panels should be in the wall t…

I got JBL GTO 1514 single voice coil 4 ohms. 350WRMS, 15 inch. It came with manual and says Vbox 3.50 ft3 Fb 30.0Hz, so is this box tuned to 30hz ? Im thinking of making new box and i really need ideas how to improve my SPL. I want to try different box, something like this: At the moment i just have vented box with round pipe. but i want to make something like in the picture, so how can i calculate box size ?

I been going back and forth about taking my rear seats out my crew cab silverado.The idea that i have if i remove the seats completely, is to build a enclosure/amp rack that rear passengers can still sit on and still be comfortable. I was thinking about covering both in some type foam and vinyl...have this been done before and would it work?

im converting 4 3" round ports to 1 square port. i made a 4x7 square this just seems smaller then 4 3" round port... please help.

I am getting ready to make a box and need to know two things. I am building a box for a nightshade 12 and I got an aeroport. The box is going to be sub up port on the side 1) Can the port be inside like old times? The only reason I am asking is all I see nowadays with aeroports is crx style with ports out of box. Will I lose db's by putting port in instead of out? 2) If so how many cubes roughly would it take up? Port will be 15.5 inches long and its a 4 inch aeroport. I am trying to see what I need to make dimensions of box if port is in instead of out. I just want the best possible setup I can get for what equipment I have.
