SPL & SQ / Fabrication

hello all! I have a 99 single cab Silverado. I'm wanting to put my 15" BTL N2 in the truck but i've never done a blow through. my concerns are how big to cut the hole out through the cab, should I make it as big as the box? or can I get away with having a smaller hole (only a few inches smaller) I have another BTL that needs to be reconed but, I don't have a amp that can push them both. so for now I want to just put this one in. would a 4th order be a good design or just a slot ported box work better (I'm not a fan of aero ports)

i have a 2005 tahoe with two orion hcca 15.2 and want to build a box like the one steve meade has for is 4 18's here a couple of links...sorry dont know how to put picks up https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&docid=x6V8eu8o53qyjM&tbnid=EQYYPTVbyxj2eM:&ved=0CAUQjRw&url=http%3A%2F%2Fstevemeadedesigns.com%2Fhome%2Fmemberbuilds_5.php&ei=Js_tUumTLOqe2QXA8oHYDg&bvm=bv.60444564,d.b2I&psig=AFQjCNEvJXWf_OhHZbJlaEYPPEtNZET1bA&ust=1391403157918733 http://cs12828.vk.me/u109393749/video/l_a71dab0b.jpg

Why is it that many many build lately have a box similar to this: (no math was used- just a visual interpretation) I guess what I don't understand is how those lil flaps on each side are a port....just seems like an open hole to me. Are these boxes more musicl or SPL oriented? i am assuming SPL, as most that I see are in competition vehicles.

My current box is 36"x16"x28" tuned @30 for 2 icon 12's.slot port.My question is would I benefit from building a new box with the port centered between the subs and fire the port thru the rear arm rest.Back seats don't don't drop down.98 pontiac gtp.

Hey everyone, Long time lurker here, finally decided to pull the trigger on a 12" ICON and would like recommendations for an enclosure. Given my driver choice I'm obviously going for sound quality. But who doesn't like a little bit of output? It will be going in an IS300 and run off of a PDX M12. My ICON will be seeing anywhere from 500-1k watts depending on where it blends best with my front stage. Anyway, I noticed that on the product information page for the ICON there are two different optimum enclosure size recommendations. Under the "Enclosure Recommendations" tab it lists ported optimal as 2.25 ft^3 @29-34hz whereas the "Pre-Designed Enclosures" tab has a l…

So I've modeled my Crystal cmpx2 12" and it is completely flat from 30Hz + in a 2.1 cubic foot box tuned to 22.8 Hz. That's perfect but I'm having a hell of a time putting it together. I have my max dimensions but I'm stuck. It's a slanted box in the back. Can someone put something together so that I can get this built asap? Height can definitely go down, and width can definitely be made smaller, but I'd rather it be wide over tall just to look symmetrical. I dunno why but I'm insanely anal about symmetry. 40"w x 18" tall x (9 1/4" d1 /// 14" d2)

I don't want to run rear speakers, and I was told here that 6's wouldn't keep up with what I was running, so I thought I'd try to fit 8's in the front doors. I remember hearing that someone here had done it to their blazer without pods, but I don't remember how they said they did it. I would run a pair of Crescendo PWX-8's and a pair of their tweeters. If the eight had trouble reaching up high enough, I could put a pair of 4's or 4x6's in the dash, in the factory locations to help with vocals.

I decided on a vehicle, and am just waiting for my check; In the mean time, I have some money set aside to start on the system in the new truck. So far i've decided on the equipment for the front stage (Zed and Crescendo speakers) just not how many lol. I think $1250-1500 is fair for a setup; and that's what i'll put towards the subs. (tax money will pay for the front stage ) My goal is as loud as possible below 40hz. I sold my BTL this morning, bittersweet, I only got to enjoy it for a few days before losing my truck But the new plan is a bunch of obsidians on a hifonics BRX 2400. I'm thinking four 18's, 24cubes @ 30hz. That is about half the budget there, plus…

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.

Hello All, I am currently in search for a really good Mid-Bass Driver. My budget is around 200$ per, it "could" be stretched a little higher if needed. I currently am a competitor for the SPL side of things, but for this upcoming season, I am also wanting to compete in SQ. I am not wanting to become a world champion per-say, but I would like to earn a respectable score. Yes I do understand how judgmental SQ can be, as it's all person preference, as well as a judge to judge scoring. For this portion of my audio system, I would like to ignore my SPL installation, and to strictly concentrate on the SQ aspect. I am currently and will like to continually run an 2 way acti…

I have an 08 silverado crew cab, I just bought 4 sd-2 10" shallow mounts and I need to build a 4 cubic foot ported box. I took my backseat out for now so it doesn't have to be complicated, and I am powering them with a saz2500, and if you know anyone that can build a box so I can put the seat back in that would be great too.

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?

I picked up a btl d2 for 250 tonight, and have it in 4 cubes at 32 hz. I need a box to really let it shine. I was thinking 8cubes @ 30hz. I am unsure of how much port to have though. Most likely a slot. My question is what is a good rule of thumb to go by for port area? I've heard mixed things about the 12-16in/cube rule.

I have 4 Sundown Sa-8 V2s that I am thinking about putting in a 4th order box and I have a few questions about how to design it. 1. Do I use the manufacturer's specs for the sealed part? 2. What is the best ported to sealed ratio for a box that I would like to have an output of 20s+ hz? 3. Would tuning the ported area to 45 hz give me the best range in frequency response? (Maybe 20s-60s or so)

I searched the forum for any previous posts and information on this and came up empty handed so I apologize if this has been covered before. I finally talked to my buddy about the fiberglass stuff he was talking about that came ready to go, all you had to do was mold it around whatever it was you were using it on and let it cure. I found out that it actually cures in sunlight, or under UV light and has a wire mesh in it to help it hold it's shape. It's not horribly expensive either. I found 1 sq.ft. pieces for $24 at Jeg's of all places which I didn't think was too unreasonable considering it's got everything a person needs to make it work. I would imagine that by t…

i will have 2 or 3 amps in my truck to power my speakers. I want to remove them from under the rear seat and build some type of mounting device for them. i have an 8 cubic foot box for my SP4 - could i mount the amps on the side of this box or on some wood attached to this box OR would the vibrations be less than ideal for my amps?

i have my cart full and about ready to order in the next few days so what I need to know since ssa store does not carry fuses what website do all of you order your fiuses from

My friend just got his first non kicker sub and he got a fi bl 15 he is putting it in the back of his Chevy extended cab he can make it about 15-18 inches deep 17 inches high and can be up to around 50 inches long he wants his box about 5 cubic feet and 32 htz can anyone help with a design

Can someone help with ideas for a new enclosure? Wanting to figure out the port velocity and everything . Model everything right for this one. . Trying to get a new computer so I can do everything my self and learn everything but in the mean time need some help.

So I don't have a lot of tools and I don't feel like ordering flush mdf rings so is there something else that I can glue to the base of my ring cut out to give it that same look when I fiberglass them...I do not have a router and I'm not going to buy one just to make 4 flush mdf rings...so Im just wondering is there anything esle out there.

Hey guys. I need a little help designing a ported enclosure for my new Crystal CMPx2 15". It's going to go in the trailblazer for now. I listen to nearly everything so I'm looking for a good daily build. I could be off but I'm thinking I want to tune somewhere between 31-33Hz so I can get some lows. My size limitations are 46" wide x 16" high x 14" deep. I have a little wiggle room on height and depth, but I'd like to keep as much space as possible in the Trailblazer. I will post T/S parameters below and I expect to be running at 1500+ watts with maybe a little headroom, probably going to just grab a RF T1500bdcp, unless I get a better deal on something else. I'd really…

I currently have a 12" Xcon d2 with a bc2000 wired in parellel in a 2 cu. ft. net box tuned to 32 hz. with 38.5" of port area and love the sound. It is in a 98 mustang with stock alt, stock replacement battery(under hood), 0 gauge all the way including big 3, and marine deep cycle in trunk. My 2 concerns are running amp at .5 ohm until i can get a second bc2000( not sure how long it will be until i get it) linked at a 2 ohm load. Before i link the two i will upgrade the alt. The second concern is space as i only have 31W x 12.5H x 29D max. I really want to keep ported but if it isn't optimal then it might have to be sealed. So I guess I have 2 questions. Can anyone help m…

Looking to get help on designing a box for a 10" ssd on a hatchback fox body mustang. This is for daily use by my gf. And would like help if possible from someone that is familiar with fox body mustangs hatches as they are small. Can someone please help im interested and having the box tuned to about 32 or 33hz.

So maybe I'm confused and doing this wrong but I haven't had trouble before. I've been modeling a pair of BL10's based on T/S parameters from the website. I've been told that they work great tuned low for a flat response but they seem to model great on 2.16 cu ft each at 31 Hz. Actually when I run them at 24-26Hz they kinda look like shit. Am I doing something wrong? Or does the 31Hz tune look fantastic for a build? The blue line is 2 drivers in 4.327 cubic feet at 31Hz
