I would like to build a ported enclosure for a single 12. I'm ok with building it but I'm not to positive on figuring port displacement and tuning and I figured someone here could probably help. I want the box to be 2 cu ft after port and sub displacement tuned to 32-33 hz, double baffle, sub and port firing at the trunk. I want to have quite a bit of trunk space with the box and amp in there. I measured what space I'd like to utilize and came up with 16-17" tall(preferably 16) x 24-26" wide x 16-17" deep, is that big enough for size box I'm wanting? For anyone curious I plan to run either an icon or a ssd off my sae 1200. I'm going to use one of my Orion xtr pros until …

Hey all.Im going to be getting my taxes back in a month and im going to get myself a new car.I want either a 1990-2000 model chevy blazer or a mitsubishi 3000gt.Ive wanted a 3000gt since i was about 13 (Im 20 now) and this may be the only chance I have to get one.I know I can get loud in a blazer but could I get as loud in a 3000gt?Like if I put a FI BTL 18 n2 in the blazer with a aq2200 for an amp and has the same thing in the 3000gt,which would be louder?Thanks.

The enclosure designers under tech are to difficult for me to build only becuase of the 45 degree angles i dont no how to cut. I already spent a little over a grand on a AQ2200d, and two bl 12's. And i dont want to spend anymore money. Can anyone on here design me a box?

Ok heres the deal Im trying to figure out the best way to do this so everything is compatible. First, I will be installing 2 shallow mount earthquake sws 8" subs under the front seats in a bmw 5 series which will be replacing the factory subs and one dcon 10" in the trunk. The earthquake subs will be run as a sort of midrange/sub and can only handle about 150rms. The dcon is good for 300rms. My questions are: What impedences should I get for the subs? Dcon 10 and earthquake? What amp would be best? 3 or 4 channel? 4 channel run in 3 channel mode? Any recommendations on amp? Maybe a link or advise on how to wire it up? '

Why does my jeep liberty hit its max spl of 142.7 at 50hz ? Box is tuned to 35 hertz

So i've been working on box design for my new SA-15's. For external dimensions i have: 32 wide x 20.5 tall x 24 deep for 7.55 cubic feet before port volume or displacement. Wood thickness is .75" Then for a port, i would have the dimensions 30.5" wide , 4" tall and then 18.16" deep. I got the port dimensions from CarStereo.com. According to that site, the box is tuned to 32hz. I was wondering if that was correct or not because i know tons of those sites end up being wrong with tuning. Here's a picture describing my plan. The lines in that picture are parallel... I don't know why the camera says differently. So does that sound alright? If not, can someone please correct m…

Are these dimensions good for two bl 12's? 1.) 36x19 57/24 top 2.) 36x19 57/24 bottom 3.) 13x18 25/64” side 4.) 13x18 25/64” side 5.) 14 ½ 31 ¾ front 6.) 13x36 back 7.) 13 1/8 x 13 port 8.) 14 13/16 x13port 9.) 13 x 31 ¾ front 3.2cuft tuned to 30hz

Does anyone know if there are any stereo comp's coming up in NE PA? Does anyone live in or near NE PA have a meter? Been a long time since I had my truck metered, I and thinking of re-doing my entire system and would like to get a before and after. Thanks Chad

Hey everyone I have 2004 Ford F-150 STX regular cab and I am downgrading from my 2 12'' Memphis C3's to more of a sound quality setup. I am thinking of going with one Sundown SA-8. I really dont know much about these woofers but I have heard great things. What kind of box would be best for a SQ setup with that sub? Here are a few pics of my old set up in my truck so you know what I have to work with. My truck

The first verse will make any SQ junkie cringe. I just think it's hilarious!

I was looking around on some forums and i saw http://www.****/forum/showthread.php?t=61103 I wondered why you would need that, so i looked at his build log and found http://www.****/forum/showthread.php?t=64796 Wow, well i guess i can't say Car Audio classifieds.So just copy and replace the "****" with car audio classifieds So this raises a couple of questions for me, i am still new to car audio, well the big league car audio anyways. Why does he need that many 1/0 gauge wires running to his sundown amp? I understand that maybe the resistance is less but still... Do i need to do something similar? Also, i noticed he has two sets of power, how exactly does that work? Is it…

I have seen it talked about here several times but i cant find it for anything. What is a program i can use to analyze the frequencies of songs i have? Would like to see what frequencies certain songs are playing at.

I have a 15in fi q that I love but i want more bass. Im running 1500 rms and i dont want to change my amp just my subs. Im looking at the sundown sa 12. I would be getting a pair and making another custom ported box. Ya or Nay?

Well, I'm pretty much excited right now. Just ordered my new BTL N2 18 a few minutes ago. Just wondering if you guys think an aq2200 will do the trick of supplying this beast with the power it needs, and if not, feel free to give me an affordable suggestion. Also, do you guys think a high output alternator would be necessary for a late 90s Tahoe if I wired another battery in the trunk?

Who is under the impression that bigger ports have narrower band widths compared to smaller port boxes? I have heard this a few times in the last few days. I wanna if this is a common miss-conception.

i did some repair work on a truck, the guy had it installed a few years back at a place in austin that went out of biz after year and years of serving the austin tx area, anyhow.. they had a rope, that went from the highs amp, up the head unit.. so that you could just tap into the factory door speaker wires from the harness, inside was of course 2 puple 2 white 2 green 2 grey. and a remote wire blue, all inside one rope the size of 0 gauge, i wish i would have remembed the name of the company planly printed on the can casing, but i dont, has anyone ever seen this ? and ya know where i can get a bunch? thanks,

Ok guys I recently upgraded cars and I am already desperate for some bass I am restricted by space since its a convertible but I found a solution that keeps me and the gf happy Space was a huge issue so I have decided on the most bass i could get out of flat sub....nothing like my btls I will be running a single JL 13TW5 but the problem is they have a single 3ohm coil......which is really frustrating that means i cant bridge a two channel and a monoblock will not be making optimum power so i want to feed this thing 500 to 600 watts but am having trouble finding an amp that will do it, where i dont feel that I know the jl 500/1 v2 will do it but 400 dollars for a 500 doll…

what is the song on the first 15 seconds of this vidreo? Is it just a made up intro or a full song. I'd love to rock it in my ride!

I was curious to how it sounds and performs to get input with out having to do it and then tear it apart if its not what I want! So if you know anyone that has done it or you have heard it please share your input!

When ever i cruise around with my brother. He somtimes likes to turn up the volume to the point where the bass isnt clear at all but has a muffled sound and isnt as loud as it was at a lower volume. Also the speakers distort at such high volume. I hate to admit it to him but he thinks when the bass hits at such high volume the bass that is traveling towards you is being messed up My belief is when you turn it up high enough, the air flow in the port cause too much air flow and can cause port noise. You can accualy hear the air moving back and forth in the port. My brother's box is about tuned to 46 hz and is about 2-3 c ft. a apline type r with 1200 watts rms

Hi folks, after a long f'd up process trying to figure out what was wrong with my tarantula amp. I decided to trade a dude for his autotek mean machine 3000.1 (before maxxonics bought them). Anyhow, that amp is only 2 ohm stable bridged. Therefore, I can only run 1 of my Ti Elite 12's (dual 4ohm). It simply is not enough output. So I thought about it and decided that The happiest I was, was when I had an 18 Cerwin Vega circa 1998. After selling my last Elite, I will have roughly $400 for an 18. I decided to make my car a 2 door and take the rear seats out and put the box back there. I don't want to wall it off.....yet. So I should have plenty of room for whatever Driver I…

Well as much as it pains me to have done it the x-cons have been sold to stefanhinote. I was in the search of more SPL and i made a final decision on two 15" BTL N2s. Let me tell everyone now by no means are the x-cons quiet i recently got a 148.2 on music sealed. Thats in a box tuned to 30hz and not the optimal port area for spl. Mind you while doing this they sound simply amazing. Ill never stop supporting SSA and i can tell you guys now my next car will be another set of x-cons for everyday ground pounding. For now though i wanna compete and its time to move to something louder.

Hi, I have a 1999 blazer with a single 12 Fi Q powered by a cadence zrs-7000d which is running at about 1300 rms at 1 ohm. The Fi Q is in a 2.2cuft L-Ported box tuned to about 32 hz. I really like this sub woofer but i am looking for more output. I have some questions now. First, i am looking to add another Fi Q 12 and making the box to about 5^3, i would be buying another zrs-7000d and bridging them together to get 2600rms at 2 ohms. Would there be any better subs that would give me noticeably more output out of a 5^3 box with about 2600rms? Second, would a new 250 amp alt and a optima yellow top under the hood be enough to support the electrical for the 2600watts? Third…
