SPL & SQ / Fabrication

Ok so I have an 02 extended cab gmc and Im wanting to put some subs in. Im looking for it to be loud and clear. Im willing to lift the seat up 2 inches. Im not sure if you guys have worked with my type of vehicle before. So far im looking at the icons mainly for the sq but I want loud aswell so maybe the AQ HDC products. Maybe suggest subs and box makers or sites to go for box. Im wanting to do 2 subs under the seat but not sure if I have the room. Any and all help would be appreciated.

I haven't seen much on center consol builds and what I have found people seem to frown on them, but my brother has always wanted to build a custom center consol for his truck. Its a 2006 Chevy Silverado extended cab. He now has my old equipment and we are going to start on it. The sub will be a 12" death. It will fit between the two front seats, firing towards the rear of the cab. The center consol will be built all the way to the bottom of the dash, so the required airspace won't be a problem. The only thing I'm really not sure on is how to run the ports. We could build it so that the port either fires towards the driver side/passenger side of the truck, or both. …

As the title says...I have 14.25 cubes available. I want to run 2 zcon 18's. I don't know anything at all whatsoever about designing a box. With that said, after subtracting driver displacement, port displacement, and bracing, will I have enough room? If not I have a Zcon 18" Dual 2 for sale lawl

hey i have a 02 ram single cab and just took out my center seat out in order to create more clearance and air flow for a sub/box. my question is; what is the best placement for my sub for sq? this is what it looks like w/o the center seat: and another shot: http://www.dupontregistry.com/Celebritycar...C-9363FD33193B} thx in advance

hey guys i'll follow mklett's pattern Vehicle : 2012 chevy cruze Location in the vehicle: trunk Space available (Length x Width x Height): 36x16x24 Subwoofer make and model: american bass xfl Subwoofer Size: 10 Number of Subwoofers: 2 or 3 Type of Port (Kerfed, Slot, Aero, etc.): slot or aero What type of music do you like?: mostly hip hop/rap but also rock Is your goal SPL or Everyday Music?: everyday Tuning Freq (Hz): 33-35 Volume :??? Questions: i'm trying to figure out the best possible orientation, size, port, and tuning for this car. i have a prefab ported box for 2 tens that i've had in the car for 2 weeks and have played it firing into car with it sealed off using…

Ok I have an 08 atima coupe and just redone my trunk floor for new box. Anyway I have 3.7-4.4cuft (internal box volume) to play with, I'm pretty sure a round port isn't going to work and not sure how to go about a slot or sqaure port. I know I need around 52in of port area for 32 to 33hz but I'm just stuck due to my box shape which I uploaded a picture of. any suggestions would be great.

So my game plan is to do 2 twelves facing front with port facing driver side rear fender area. The box width is going to be just wide enough to accommodate the subs so a little more than 25" but would it be better to have the height about the same as the subs or would it matter, in terms of SPL? If it's around 13.5" (internal height 12") then I wouldn't be able to stack the 4" aeros. If it's 15" then I can stack them but to me, I feel as though the more streamlined shape of the other box would allow for higher SPL. The taller enclosure would be shorter on depth too, obvioulsy. I could also just be thinking about this way too much but whatever

I am planning on running 2 15" HDC3s (copper) and im either planning on doing a slot port in 8cubic ft tuned to 36hz with 2 AQ2200 OR I've been thinking about doing a wall, about the same size or bigger, tuned to the same (i think) -- I'm thinking the wall will give me more output/power??? - thats what i need to know I have a 86 s15 and this would be my first time for a wall, so i dont have a lot of info/knowlage on walls. -im rushing to go to class, i know im lackin info and mispelled words thanks dom

I Just got a pair of Eclipse 8062 6.5" mid-bass's with there crossovers, and no tweeters for $60. I thought it was a good deal so i got them, I needed a upgrade from my polk db 4x6's. I tried the eclipse out in the house in a quickly made box and they sounded great, but I cannot get them to fit in the car where they will be completely sealed like they need to be. My speaker holes are 4x6" on the top of my dash facing the windshield in each corner (I will post pics). I need help figuring out a good solution to where they will sound good and look kinda decent in the car. I can't put them in the doors and i am not allowed to do any permanent modifications to this car. So wha…

Hey guys I have a Fi BL 15" fully loaded woofer on the way. I will be building my box very soon here. I'm going to be running a Sundown 1500 D amp to it. I will listen mostly to low HZ rap or bass songs. I am looking for 32 HZ. Few questions: - Can someone give me some measurements for a ported box that is meant specifically for a BL 15" with 1500 RMS going to it? - I have read that this sub woofer recommends a 3-5 cu ft box. Does leaning towards 5 cu ft box have any benefits in SPL? -Any internal box bracing necessary with 3/4 " MDF wood? - Any cotton material necessary inside the box? Thank you

yup, the shit's still in the ceiling and it's gonna stay there. if you need to hear the drummer strait ahead and back 7 feet, the back up singer come 3 feet deep from 7 feet from your right, lead guitar and vocalist strait ahead yadda yadda... if you're all about staging, imaging, using time delay, phase, and EQ.... GOOD FOR YOU! I like it loud and clear. it is loud and clear. I like a ton of midbass and a ton of high treble and easy on the low treble and easy on the midrange. So this thing has come a long way, I now have: Alpine IVA-W505 touch screen DVD player so that I can use the touch screen to control the digital Alpine PXA-H701 crossover/processor. I have (2) Kick…

Hi i'm new to SSA forums but been around for a while on others. Who has run any type of isobaric set up before? The low end is efforless and immense and all from a smaller enclousere. Also the smaller cab plays the higher freqs really well and just makes for a very flat output over the whole range whilst still staying controlled. Basicly the iso' only makes use of the extra motor and has no real use of the other cone. Or even the other basket for that matter although the other basket make the whole rig easier to mount. I am thinking about a dual motor design and just simply linking the the 2 motors by extending the the formers so they meet. Who thinks this is a good idea…

So I'm trying to make a center console and I'm going to put some 6.5 evils in both sides of it. Seeing is the mids are facing back to back should I put a divider between them? Is it going to call his cancellation if I don't? If I do or don't should I be putting polyfill inside this also?

Designing a new enclosure for a Fi Q18. I want to be sure that sub placement would not cause any issues with unloading thru the port or odd loading issues off the port wall. It is only a single sub, so I dont believe the loading off the port wall would be an issue. Here is a quick sketch up of the enclosure. The guide mark is the mounting depth, and is approx 4" from the back plate to the port wall. I would prefer center placement just for aesthetics but functionally I believe the position closest to the exterior port vent and above the port wall may be the best bet. Thanks for any insight

I remember talking to shizz and a few other box builders on here and they all said "if the box is built well enough, no bracing is needed". Well is this true? I am working on a new box for my 15" - 38"w, 18"d, 16"h. I dont think I need bracing for a single 15" in that box, but I could be wrong (its a little oer 4.5 cuFt with port tuned to 32hz). I have been looking at other posts for people building their box and its either hit or miss for who does what with bracing. The one I just finished looking at is using bracing for a smaller box so once again, I am not sure. Forgot to add in - I will be putting a DC Level 5 15" in the box being powered by a 3500D

I have seen a few posts on here recently about trunk cars and the difficulties that some have experienced with their sub bass system. I think this may help. There are a few primary problems that are encountered when we install subwoofer enclosures into a sedan type vehicle with a trunk. The most obvious problem is the reduced amount of bass in the main listening cabin. The next possible problem is that there is more bass with the trunk open than when closed. A third problem is the excessive rattling of the trunk body panels. Proper damping will greatly reduce the vibrating body panels and yield slightly higher SPL in the vehicle, but will not resolve the other issues inh…

I want to make some MDF speaker rings that look something like this: But I want the 6.5 and tweeter to fit flush with the mount. Should I just use two pieces of 1/2, and make the inside ring the mounting diameter, and the top piece the outside diameter of the speakers, then glue them together? I may just have to do some experimenting. I'm going to try and mount them in the door in place of the stock 5x7s. I've been thinking of fiberglassing them into the doors, and I probably will in the future, but I just need something temporary right now since the XXX 6.5s will be here tomorrow, along with my BTL. All I'm waiting on to build my sub box is two 3/4"x9"x18" pieces of ple…

I am building a box for 2 SA-12's for the trunk of my altima. I want to have a square port between the 2 subs on the front of the box, looking somewhat like this: O | O sub port sub Using 3/4" MDF and outside dimensions, my box's height can only have ~ a height of 16.5", a width of 33", and a depth of 16.5" (however, the depth can be altered a good bit if needed) I need to know what dimensions to make the port and the dimensions of the box itself if anyone could help. Thanks.

Sorry if this has been asked before but if I decide to get a loud exhaust system is it worth it if my system is my main priority and by is it worth it I mean will it take a full shop pack of deadner for it not to affect my system?

** Coles notes: 12" BTL (D2, loaded, Daily). Maximum Dimensions: 31" x 16" x 18". Want to hit the lows better. ** What is required to build a box specifically for lows. Larger box? More/less port area?.........etc. I had a BL last year, and have "upgraded" to a BTL this year. I have two boxes that were used with the BL, one built by Thumper and another I did myself. The PTS box is tuned to 32, I think mine might be tuned lower, not really sure. Used subwoofertools.com back in the day, and it told me it was 32Hz after displacement. It's 27" x 16" x 18" with port 14.5" x 2.5" x ~33". 3/4 MDF. When I put those dimension in RE Calculator it comes up with 29.81Hz (before dis…

I am currently looking for the best method or material that can be used inside an SPL based enclosure that can help get an extensive increase in pressure. Lots of people do different things but most follow others... Typical things tried is- sanding wood, applying resin, resanding, resin over, etc.... Ceramic tiles. Using heavy material such as marble or granite(not what i'm looking for). I am looking to find out if sanding and resining is what should be done, OR.. if laying material inside of an enclosure will yield better results. sanding and resining can lead to human error with imperfections in the smoothness and this is why i'd like to see if there are materials out …

Okay so i already had a box designed before but i wanted to try it all on my own...thanx to the12volt.com box and port calculator i figured out a simple box i can build...here are the specs BOX: W-47" H-25" D-28" PORT: W-30" H-5" D-10" The box will be 16.4cu ft and it will be tuned to 35hz...the port will be facing back with subs fired up/inverted...

So heres the deal I need someone to design a Transmission Line for one of my ICONS!! I have decided I want to start playing with a variety of different boxes. It will be a single 12in Icon or we could even do a Horn design which ever fits lol. It will be in my Hatch! So whos up for the challange I can get you Dims...

Hey fellas, I'm looking to change box design. I want it to be port forward. The dimension I have available is 32"W x 12.5"H x 29"D. It is running on a bc2000. I am trying different boxes until I can get another xcon and have no experience with 4th order builds. It will be a 98 mustang trunk wall. If there are any details you need let me know as I have no knowledge of 4th order designs. Thank you to anybody who helps.
