SPL & SQ / Fabrication

Ok, well My trunk openings are garbage, my trunk is HUGE but, I can't get a box inside the trunk from the rear or from the back seats. So, my only 2 solutions are this. 1.) I lay down plastic so I don't get anything in the back of my car, And I pre-drill the screw holes and put the box together while it is in the trunk. Only problem i see with this really, is the internal piece for the slotted port. 2.) I build the box split down the center, having a top half and a bottom half, which would be Biscuit jointed or using dowels and thenglued together in the trunk, and then over the joint external strips would be screwed into place to hold the joint together. Both of these are…

Would it be possible to make a transmission line box for 2 18 Q's in an area that's 16" tall x 39" wide x 70" long with an additional area of 22" tall x 52" wide x 10" deep OD? Like this: Would having the subs mounted off center make it not work?

I was playing around i bbp6 and this is what i came up with, is this right or wrong? Optimum Square Prism Box Parts 1 Top, 1 Bottom: 13.27

I'm going to build a box for a buddy of mine that has a 1988 Camaro Iroc-Z. It's not going to be in the wheel weld as of other boxes. But right behind the rear seats. In this picture where the amp is located, there will be an enclosure for them, and it won't cover up the whole trunk area. I am going to use dual 4" Areo ports, and I was wondering how long will they have to be to have a tuning of 32-32hz. I'm thinking 1.6-8 cubes in total for both subs, and the amp I am using is a Polk Audio 4channel 800 watt amp that will be bridged to run at 4 ohms. The aim is mostly for SPL since there is no true SQ. But he would like to be able to listen to a variety of music, such as:…

I currently have 2 SA10's in 2.5 cu ft net tuned to 32hz. They are running at 1 ohm off an SAZ-1500D. I'm pretty happy with them, but the box is the wrong shape to fit where I want it. This is going in an 03 Lincoln town car on the hump behind the seat on top of the gas tank. I have 41" of width, 18" of depth, and 10.5" of height. So I should be able to get 2.5 cu ft net, but just barely. One reason I'm considering the skar subs is that I get a free box. I can get 4-8's in a custom ported box shipped to me for $500. Or 2-10's for $380. I've been thinking about 8's since the sa8 came out. And the box would look nicer for 8's since I could do a flush mount baffle. I don't h…

Hey guys I have a couple questions. I did a build on 2- SA-12" V.2 Nightshade and I had a custom box built that is 3.0 cf box w/ a port face that is 40x1.2" and is 23" long (specs I got from SA). The subs are firing up and the port is firing back at the bottom of the box. This roughly give me 48 inches of port tuned at 36 hrz, I heard from SA tech that I needed 15 inches of port for each SQ FT. It sounds great, the only problem is it doesn't sound as loud as my ProBox super bass box did. Any suggestions? I talked with SA tech again and they said raise the tuning frequency by cutting off a little off of the port. I checked with ProBox and the Super Bass Boxes are tuned at …

im about to trade for 2 SSD 18's just to mess with for a bit. so im planning on running about 11.5 cu ft at 35 hz, but gonna make interchangable ports to play with different frequencies. so should i port it forward, or up. subs are gonna be facing forward in a 01 dodge ram ex cab BTW

Im pretty sure Ive seen this before. wondering how the port length is calculated. say the port opening is 3.75x13, Id assume when it splits Id make each continuance of the port 1.875x13. do I measure the length of the first part before it splits, and add to it the length of the part after the split to get the overall length. do I calculate the length as if I were running 2 1.875x13 ports, or a single 3.75x13 port. with the box volume and tuning I was using, they were very similar, 29.6 for one and 28.92 for the other scenario, so either one would end up close enough, but Id like the know the correct way. if either of these are correct.

about 2 months ago I (with the help of M5) set up my first 2 way active system. Since I have lost the rear speakers and I have my sub crossed in at 50 htz with a 18db slope I now have a serious lack of sound from about 60 to 140 htz. The Bostons I had just would make this honorable noise at about 150 htz, just muddy and nasty. So i just got myself a pair of the new Rockford power components and STILL THE SAME PROBLEM what do I do??? I have already put dynamatt in the doors and on the back of the door skins. Do i have to take this thing 3 way in order to get some mid bass?

Can I mount the subwoofer in the port, like this? And... Would a 12"Height 1"Wide 6"Deep port be the same as a 6"Height 2"Wide 6"Deep port? Would it sound any different?

Hi there wonder what's yr opinion about such setup: 2 x 8" by AudioPulse (Epic D2) questions: 1. go sealed or ported? 2. how big should be the box to achieve lower frequency response (~32hz)? 3. will this setup be enough efficient to shake my car or it's better to go with 2x10" ? thx

Would this be a good box for 2 xcon 12s running a crescendo bc 2000d I'm planning on running it at 2 ohms because I'm hoping to run stock alt with an extra batt. in the rear for now. I was hoping to run sub and port forward sealed from the trunk so my max height is 18 and width is 32 and that's real tight. If someone else has done this I would love to see pics for reference. http://i1257.photobucket.com/albums/ii511/trpkkd/accordbox.png

Looking ~15^3 after displacement with 18.5 x 9 slot port on driverside tuned ~34hz since it will be at B pillar. Had talks about tuning it higher since it will b pillar (midgate) and will go lower anyway in Hz's. Also to do center ports with separate chambers instead. Will be running a Memphis Mojo 4kw and have upgraded my electrical. Looking more at a daily setup and a shared chamber with slot or separate chambers.

Hey guys I just recently got two SA 8s and I am getting ready for a custom enclosure. I have been thinking about maybe upfiring them into the rear deck of my new Infiniti M35x and cutting holes for the port and woofers. The only issue is that I did this with some Image Dynamic 8s and wasn't thrilled about the how they sounded. Certain people say that give you a cleaner sound any input? I was also thinking about doing something funky like firing port backwards and subs up like you would in an SUV to see if that made a difference in the trunk. Should I just stick with the conventional trunk box? I was also wondering what people were running for box size (i heard .6 per sub …

I'm preparing a box that will hopefully be home to 2 15" Xcons that will be powered by a saz-3500. My goal is not to get the best spl numbers. I do listen to a lot of rap yet at the same time I enjoy some Lenka, Utada Hikaru, or miss Swift to give some examples. I think I would like to tune around 30 or 31hz. So far, I was planning separate chambers and double baffle. This will be going in a smaller SUV, probably subs up, ports back. I am doing all my calculations and sketches w/ pencil and paper, so I may be off alittle due to rounding or way off due to poor math skills. Max available space is 26L*37W*24H, after divider and sub dis I am thinking the box is 10.3ft^3. I fe…

I've been trying to decide if I want a single Din, Double Din, or possibly Car PC in my truck but I think the question can really only be answered after I decide if I want to go 3-way or 2-way Active. I have now currently installed one 2-Way Active setup ran by an 880PRS so that is my extent to an active setup. I have been told to do a 3-way I may have to go with a robust 7 instead of an 8 but would really prefer squeezing an 8 even if that means a custom door pod that I have seen made. I have no problem with using the kicks or glassing as well So I'm really looking for some Pro's and Con's between 2-Way and 3-way. The more I think the more I really just want to go all ou…

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 well I'm building my new box for one SA-12 it's gonna be 2.48 cu. before port and sub displacement.I'm gonna use one 4" aeroport.It's gonna be sub back port side going in a trunk car tell me what ya'll think?

2 part question, lol. 1). I'll be getting an '05 Chevy crewcab next week sometime, and I was wondering if it's possible to get 2.5 cubes anywhere from behind/under the rear seat? 2). If not, I may consider a blow through. The problem is I dont want to cut a big hole. What effect on tuning would building a box like this? Thx for any/all help you guys can give. :clap:

A buddy of mine wants me to build him a subwoofer box for two 12's in his Ford Ranger Edge. Now he is taking out all of his rear seats which gives me a good chunk of space to work with. I know how to build and design an enclosure, all i really need to know is subwoofer/port orientation. Havent made an enclosure for a truck like this and I dont have the time to build multiple enclosures and test them all out so I was hoping this could save me some time. -Mike

Alright, iv basically all over the map trying to consider what type of subs i wanted. Iv made up my mind now and i kind of wanted to know your opinion. I was thinking about going with two Fi 12"Q's, OR two Fi 15" Q's in a ported box, running off a Crescendo BC2000D. Now in order to eliminate trunk rattle, i was told sealing it off from the trunk and firing it forward was a good idea. The only problem is that i cant fold my rear seats down, now i do have the option of buying rear folding seats for about $300. I guess i dont really have a specific question.. just tell me what you think, any improvements or different ideas you think would work best. Since im…

ok what assocation(s), classes and what equipment are you going to be running post um up

Alright heres what i have. 1 Kicker L7 15 Dual 2 Custom Ported Box 4.44 Cubic Feet Internal After Port And Sub Displacement Tuned To 34 Hz Kicker Kx1200.1-1400 Rms Alpine HeadUnit KnuKonceptz Kolossus Fleks 0/1 Gauge (About To Order) KnuKonceptz Krystal Klear Subwoofer Rca's (About To Order) Sub Is Firing Against The Rear And Port is On Passenger Side How Does That Setup Sound To You? I Know The L7 Isnt The Best Sub For Spl Or Sq But I Like The Way It Sounds. So Thanks For Your Opinions

My boy is about to buy a 04 monte carlo. He wants something loud in there without sacrificing the trunk to much, I wont have any measurements for a few days but I wasnt sure if anyone has built anything in one these and mite know some ideas for speaker and amp brands

Who will be competing next year and in what organization and class. I will be competing in SLAP in the stock 0-160 class
