SPL & SQ / Fabrication

hello i have a 02 nissan frontier crewcab i have never built a wall and need help with the design if anyone could help me im trying to get around 35 htz but the floor i weird and i cannot figure out how to upload pictures i can email them to anyone that can help or if someone can tell me how to upload them w:51 d:27 h:36

a box's internal dimensions - 10.5" high 35.5" wide 20" deep If i put a port in it width-wise, slot port along the wall, 10.5" high x 4" wide, and run it across and leave a 4" gap from the wall resulting in port length being 31.5" long + 0.75" for wood thickness exiting box... When i calculate port displacement, do i find the cubic volume of 10.5" x 4.75"(plus thickness of wood) x 31.5" or 10.5" x 4.75" by 35.5" ? Do i take into account the effective area around the port too? because if i do then i would choose the 2nd option above as part of the displacement.

I am ready to build a sealed box for my single ss rl-p 18, but im not sure which way to face the sub. i have plenty of room on all side. My car is a lincoln towncar if that helps. Also, should i go with the recomended box size of 4 cubes? And one more question, should i only double baffle the front, or should i double baffle everything? Thanks

Hey, I was wondering what the biggest box anyone has put in a WRX sedan through the trunk. I have a XXX 15 and I am having trouble getting big enough dimensions for a ported box to house the XXX. If anyone can help let me know. Thanks, Chief

Hi, just wanted to ask which box would be best for my space and will do the Best Output, I want a box it with a maximum of 4 cubic int. feet. I am going to buy 2 12'' SSA Xcon and I will like to know which type of box (Ported or Sealed) is best recommended for my space and my needs... Thank you.

I am getting ready to do a blowthrough in my truck. The subs I am planning on using are 4 Audioque hdc3 18's. The dimensions are 50x17.5x77 inches. I will be running them off of two IA 40.1's strapped. I have built several boxes but never a blowthrough. I have heard that bandpass is the best way to go when doing a blowthrough...is this true? Anyway is there anyone who can design me an enclosure for this setup? I will pay of course just let me know.

Could I get the same output if I use aero tubes on my box instead of a regular port? I want to get a 9cuft box for the new 15" BLs. Would the aero tubes make the gross area of the box smaller because I want the box as small as possible but still have about 9cuft of area after displacements?

07 toyota tacoma doublecab RE SL 10 Pioneer avic f700bt HU JL 6.5 components up fron and JL 6.5 coax in back Preferd matrial is mdf i've got a ton of it. But I am no strager to working with glass and dont mind it if will yield the best results. Im going for SQ im over the bckseat box thing. My goal is a very responsive package that will hit a wide variety of HZ. with ought ruining the sub or the amp. Have not purchased the amp yet but I am looking at Rockford Fosgate Punch P325.1 mono The space we're working with is tight Do I attempt to make an enclosure that will fit the exixting cavity in the starage area or do we pull it out and go for somthing bigger?

I have 40"x 15 x 25 to work with. Would this be sufficient for either 4 sa-8 v2's or a single dc lvl 6 18" assuming it'll fit physically. Its going in a 2005 civic sedan with a 220-250amp alt, 2-4 xs d31's and probably a stetsom 7k or similar. I would like to have itforward fire into the cabin while being sealed from the trunk.

ive been told that puttin carpet on the inside of a box will make the sub think the box is bigger there for sound better or louder. but i personaly like fiberglassing the inside to gurantee its super sealed and not falling apart ported or selad enclosure which would be the better idea or maybe carpet over fiberglass

Is there anyone here thats does them....

Ok, i just bought 2 Fi Q 15's with BP Power and a AQ2200D amp for my truck. I have a 2000 ext. cab dodge dakota and am looking for some enclosure help. I currently have an idea for a certain ported wedge design with my amps fixed to the bottom but it is only 6.2 cu.ft. net with 78 sq.in of port. A similiar design can be found here: http://mobile.jlaudio.com/gallery/detail.php?vehicle_id=1095. If anyone has a design in mind, and would like to show it, I can be emailed at [email protected]. Any input is welcome. Thanks in advance for your input.

Just got about everything I need to start the build, so I am starting to design the enclosure. Did some searching on the site and haven't really found the answer to a couple of my questions, so I will post them up here. First the box is going to be for 4 RE SE12's powered by 2 SAZ-1500D's strapped. I have the 1/0 for power and runs, and am picking up 2 new batts for the back tomorrow. This all going in the Suburban. Box size ideally is going to be 8cu.ft. with around 128-157cu.in. for port. Will see if I can fit aero's if not I'll do a slot port and this is for daily. I have built and tried 3 different boxes so far. All peaked between 40-45hz, one box being 2 1…

Alright, I know how all you guys are happy to help people with set-ups and stuff. So I got one for ya. MY brother was paralyzed sometime around birth. So he is confined to a wheel-chair. He rides around in a big-honkin van. He loves car audio and has always been interested in what other people have. Anyway his birthday is coming up soon and I was wondering if you guys could just put your heads together and help me figure out how and where to put a system in his van. I will have pictures soon. Later Today. It's a '91 Chevy Van with the back seat cut out so he can drive his wheel-chair into it. Anyway I have to go put a water pump in. Thanks in advance for all your help and…

I need some of you guys to make sure my calculations are good and that this box will work out. This is the first box I have designed to be as critical as needed. I am wanting to try a subs back and port into the cabin approach. This should work out to 6.75 Cu Ft after port displacement and after the 15 " BL's it should have 6.39 Cu Ft at about 32 hz. I am wanting to try to make it bigger and get maybe close to 4 cubes per sub. I have about 7 or 8 more inches to work with to make it a little bigger. But I figured I would make sure I am doing this correct before I go and design another one.

I am getting AA Assassin Series 12"D4 and I want to make a box for them in my tech class. My goal is to make a transmission type box. I am just not sure what you need to do it right. Like how to tune how big you need to make the vent. I want to make the box about 4-5 ft. If anyone can help me that would be great.

Single Q12 going in 2005 jimmy and was wondering if I should just go with the cut sheets found here http://www.soundsolutionsaudio.com/forum/topic/44520-q-series-cut-sheets/#entry701997 or should I get someone to design one? wondering if this would be optimal for good SQ over SPL. Should I place enclosure against front seats facing sub backwards, upwards, towards front or behind back seats facing up or backwards ?? Looking for SQ quick response over SPL. Wanting ported for better power usage and also heard ported can sound just as good as sealed so went that way and got without high QTS. Anyone have experience with single 12 in SUV ? Anyone maybe be able to design an encl…

so i got a deal on a 91 240sx hatch its in perfect shape and runs great for $1000. my dads racin buddy has to many cars so hes hookin me up. it'll be a couple weeks b4 im able to get or see the car in person cause im waitin on my lawyer to call me and tell me to come get a check. so i've been googling and youtubin all day and i can only find 1 with a real system and its walled and im not wall reaady lol. so i come to you guys for help cause i know someone has or knows someone with a 240 and a system. i am wondering if i have space in the hatch area for a good 4cu ft. box after displacements kerf ported and tuned @ 33hz for my rf power hx2 15 powered by my saz1500. so im t…

Okay, so I have very little room to work with, and needed help on how to port a wedge box. I have 2 designs I can use for the port, both are using the same box. Width: 15 inches. Height 1 (front): 12.5 Inches Height 2 (back) 7 inches Depth: 18 inches total volume (using 3/4 inch think wood) = 1.06348 cubic feet. So one idea is to place the port under the sub which is the eaisiest. 13.5 inches long, half an inch tall, 14.5 inches of port space (32hz tuned) ^ I need to know if theres anything wrong with this idea? The 2nd idea, which is more complicated, is placing the port on the side of the box. I have no idea how to calculate such a slant. Would the 1st option be …

What % can an enclosure be off on recomended net cubes. I thought I remembered reading 10% somewhere. It's a daily driver.

Hey everyone, I have a dilemna. I want to throw a nice pair of 12s (or 15s if I could) in the back of my trailblazer, but I want to save space. I have 2 young boys and I need to haul a lot of stuff sometimes (golf clubs, snowboards, etc). I have a Sundown 2000 that should be delivered in 2 days, so I want to work around it. Quentin from Audibel is going to be building the box for me, thus I'm pretty much looking at SSA or IA subs. I'd love a pair of 15" Xcons, but you do what you gotta do. I figure I have a few options. Either a box up against the back seat(rear-firing?), or a false floor(firing up). I'm open to suggestions. For the box against the back seat I was leani…

2 12" type r's at 1000wrms 1ohm ported. I'm upset with my box, it kinda sucks. The port wall isn't tall enough, and it's a little too big. I want aeroports for some reason, they've always caught my attention. I've also heard they sound better. Max dimensions are 14.5" height 26" length 37" width all external. I want the subs firing up and the ports going back. This box will be in the back of a '93 Range Rover Classic LWB. I can get pictures of the inside if needed. All daily use. Just need the box design, and cut sizes.

I like to think up things i haven't never seen done so let's get some opinions in here because i wanna see what people think how this would work - I don't feel like drawing a pic so i'm going to rely on your visualizations to see this box in your head. Let's take a 12" sub. Let's put it in a ported box at 2.5 cuft. Tuning... thats the interesting part. Ok, so build a box with 5 walls, not 6, 5. Leave the rear wall completely off. Now, let's say for quick number crunching, the box is as follows - (all external) 16" wide x 16" tall x 16" deep with no rear wall. Now, let's build another box with no sub cut out, again with 5 walls, not 6. Dimensions for this box is as foll…

I need help to build a box for one 12" Fi Q in the back of my regular cab GMC truck. I don't want to compromise sound quality and i do want it to get loud. What i was thinking of doing is fiberglassing the bottom floor behind the passenger seat where a box would normally go and use MDF for the front, sides and top. I 'm not the best at 'glassing, it works but isn't pretty. I'm trying to get there recommended size of 1.2 - 1.3 cubic feet. Any ideas to start??? If any one has any ideas please let me know i am open for suggestions. Thanks in advance I want to run a 12" Q and a Sundown Audio SAZ-1500D.
