SPL & SQ / Fabrication

i sold my crx i coudnt keep fixing it anymore my transmission went out i have bought the 18 xcon when they were on sale used for $300 and i now financed a 2003 acura cl!!! i miss my rex and now i cant use my 18 xcon i need help deciding new system i dont wanna tear my new car up but i want it to be loud and have some sq without tearin it up

I'm running an Fi BL 15 on a sundown sae-1200d in a scion tc. Bought a prefab box for it a couple of months ago but im looking to get my system as loud as possible (currently upgrading electrical as well). The box seems to be tuned around maybe 50hz or so, as in Young jeezy's song "white girl" (i believe it has a 30hz note and a 50hz note) and the 50hz one hits way harder than the 30. If i built a new box, and tuned it to around 33hz, in that song it would be the other way around having the 30hz note be the louder one correct? Heres the box that I have now: http://img841.imageshack.us/img841/1833/img2746u.jpg How much would it cost roughly to build a new box like this (s…

Hey, I just built my first box. 2.18 cubic feet tuned to 34hz, for under the seat of a 2003 Silverado. The box sounds great, but looks horrible. So, my questions are. Do you use wood glue to hold the box together? Or just screws? Do you use screws or nails? What type of silicone do you use to seal the box? Help is greatly appreciated. And for those wondering; the box was built for an RE Audio SX 10", so far we've tested it with a Soundstream SPL 10" and it sounds great, the RE should be here in a few days.

I recently got a great custom box by Audibel Customs for free but I was thinking about building my own fiberglass/mdf enclosure. The only reason I went with Audibel Customs was for the free enclosure if not I would have gotten the Mach5 IXL's. But the Custom box Quentin built is great and hits hard. I just need more space. What I plan on doing is making everthing mdf except for the base/feet of the box. The reason is because my truck has a lot of bumps/curves on the bottom behind the seats and I can gain some airspace in order to do 2 SSA Icon 10's in the future once money comes. I have learned/researched alot of other build logs on fiberglassing and think I have the capa…

I have approximately 2.6ft^3 before displacements. This box is for 2 DC Level 3 10s. I'd like for the box to be tuned around 33hz, I planned on using a pvc/abs round port. What diameter should I use and how long should it be?

Crazy, stupid, or cool? Thinking about doing wall with 2 18's. Not for spl, just daily pounding.

So I have searched a little and really haven't found out much info. I read somewhere that fiberglassing the inside of your enclosure makes it weak. why is this, is it because of the heat and chemicals released during drying and curing? Is it really necessary for a box that will only see a occasional romp on a lane? Please discuss.

I recently opened up a tint shop and have had a lot of customers wanting audio, so I just picked up the Sundown line. I've been an installer for 14 yrs now, but all the shops I've worked at did cookie cutter systems with pre-fab boxes so I never really learned how to make a box and match it to the subs. I've built plenty of boxes, so the actual building is not what I'm looking for it's just getting the correct size and port length I need. I see a lot of threads recommending box calculators like torres ect. which I've downloaded, but I don't see how you're converting the sub specs to box design. I found the AJ vented designer program which does this (I'm looking to built m…

Okay, Elderado told me that in my car, i have a gas tank between the trunk and the back seat. I actually think that the tank wall is my trunk wall. Anyways, Odds are good that I cant get wire back through any cracks there.. So, where do I put it? <pics tomorrow when its daylight> So, I was thinking maybe right behind the drivers seat in a nice sealed box with some plexy glass over the top so it doesnt get stepped on. Either that *not behind the passenger seat becaues its always moved* or I can stick it in the rear deck. Like, I could be able to drop it inbetween the two rear speakers? But I would need to check the space between the deck and the gas tank. Als find ou…

Do you guys think I can get 4 dcon 10s in a 36"w x 16"h x20"d ported

I have never done a wall before, and i am really interested in them. If its not too much trouble i was wondering if i could get schooled on them -- how to prep a truck for a wall, the do's and dont's, bracing, etc. etc. etc. I would like to become confident before going balls deep into this build and I don't want to be slapped in the face by how little i know half way into the build, ALSO i want to know what i am getting myself into before i start cutting. (ported, 10-20 cubes) i seen the build a wall build and it had a SHIT load of 2x4s.. would i have to do this to my truck? The truck will be a 1986 GMC Sonoma (S15) ext cab and the equipment is 2 or 3 (depending on how …

Hello all, I am building a budget spl system an need help with the enclosuer.I have one Sundown audio saz-1500d an two audiobahn aw1206t 12" subwoofers. The enclosure has to be under 7 cu ft outside. My car is a acura cl 1997 I have two Orbital 950ca batteries ,1/0 wire a fusion preamp with 8 vols outs. I know the flame q is not the best sub for spl but I can get them for $130.00 per set.

I have a gmc Sierra ext cab and I have a half wall box. How could I secure it so if I crash it doesn't kill me?!

so me and my buddy decided to make the box for my 15 thats on the way and here are some pics gonna carpet it soon! tell me what you think, and be honest!

Well looks like I will end up with 17.87cu before bracing and sub displacement. I really want to end up with 17cu total after. This is for 2 18in FI Q's on 3k watts. Box dimensions will be Outside 35h x 54w x 27d.... All sides double 3/4 MDF except front baffle will be triple. (may use some Birch for weight reduction) Usable inside demensions are 32h x 41.5w x 23.25d = 17.87cu Port is 8 x 32 = 256in total Sub displacement = .24... but I will be triple baffled so what maybe .22 or less?? Total of six 2in hardwood dowels for bracing =.35 2in wide 45's in corners =.10 So this leaves me with 17cuft tuned at 30hz after all is said and done. I may glass the inside as well? what…

went to a db drag tonite and i took first place. super street 1-2. hit a 143.9 legal on the new TL

So if you looked at my build log then maybe you can get an idea. If not then to fill you in i have a RE SX-12 in a ported box 2.0^3 at 35hz and after setting gains i am just let down by the lack of serious bump. I'm looking for a recommendation on to what route I should go to get more bump from my back seat area. It's a convertible and it's been said that a smaller enclosure may assist my needs. I have a pair of alpine type-r 12's gaining dust that would be good for a smaller enclosure if that helps any. Anyhow thanks fellas.

Okay guys, I need your help on this one. Now ive built a few boxes and understand the basic concepts/calcs of everything but have never built a wall before. My brother asked me yesterday if I would build him one yesterday and thats why im posting this today. Can anyone give me some tips and explain the order at which i should start it? **Now Im not asking you to explain every single thing (tuning or port size or anything like that which would depend on the subs, which he hasnt decided on yet) Thanks for any input and as always its appreciated.

Hey guys! I did a bit of reasearch but couldn't find a good topic about this. What do you guys reccomend for some good box building tips for the best box possible? Not like designs so much (Although if you wanted to post set-ups such as like...Explorer, sub up port back (as an example) that might be helpful to some), but things to do in the box. Things like: Rounding the port edges to flairs 45 degree angles in the corners for standing waves placing the subwoofer so its at the back of the port length where to add braces so that turbulence is minimized (or using rod threads or your favorites) those were a few I could think of as example and I'm not even sure if they're al…

I am going to my 2nd comp. this weekend---state finals of WV---I will be competing in the Stock SQ class and I am nervous hoping I do well---I think I have tuned my car so much it is starting to sound unnatural---I need to leave well enough alone but if anyone here knows me knows I can't leave anything as is.----sorry I had to rant alittle.

Current setup is Mach 5 MLI and Seas H1396 amplified by an Eclipse EA4000 and all the processing is done by my Alpine 9813. I'm very satisfied with the midbass output and the top end, it's just that midrange isn't cutting it After seeing Ryan2's idea with the Fostex FF85k's I thought trying a pair and ditching the tweeters. I don't want to invest in the H701 at this time and try 3-way (would require some sort of controller too and another 2 channel amp, not to mention the extra room ) The problem is placement. I have no room in the dash to mount them. Pics of the "locations" : One idea is to use the kicks. Passenger side is ok, driver's side could work but there's v…

Ok so i have been doing a lot of research for the past 3 months on my plans for a setup. i decided that i am going to go with 4 18"Fi SSD in a blowthrough enclosure designed by peter kulicki (still designing) with a Sundown 3000D (still saving up for it). but my dad told me my subs are going to kill my highs. currently have 4 kicker 6x9s doing the work but i am looking for some suggestions on an extreme setup for some highs in my single cab. by extreme i mean i want way more than a set of comps and tweeters. any help will be appreciated if you wanna check out some pics of my truck you can check it out here!! http://www.cardomain.com/ride/797852

I've decided to start murdering my truck out except with chrome here and there. So here is my start.

Im thinking about building a new box to try and improve sq in my setup a little. i have a 3.75 cu ft box with like 60 inches of port tuned to 32 now, slot port on one side of the two subs. this box is a little bigger than what my subs call for and is an awful lot of port area. im thinking about bringing the box down to 3.2 or smaller and using a 8 round port and flaring the ends tuning to 32. if my math is right 8 is 50 sq inches of port correct? im thinking about choking it down to 7" which is like 38~ and run @ 3 cu ft. im running like 1600-2000 watts BXI2006d would the round port sound better. as with the smaller box? edit" running 2 DC audio lvl4 12s. call for 1.5 c…

i have been killin myself trying to figure out a box design for my ranger and have gotten nowhere with it. i got a couple reply's on other forums but nothing set in stone. the sub is a 15"btl and my dem are 50" wide x 16 tall x 16 deep, 5.9cf before sub displacement and port displacement. i need it to have ports on both sides of the sub cause i want the sub in the center of the box (its that way to even out the weight in the truck). i would like it tuned to around 33-34hz.. any help on figuring my port length would be great. please put in laymans terms cause i am not very bright when it comes to this kinda stuff. any help would be greatly appreciated, thanks btw the sub…
