I've had some problems finding info and figuring out how I should build a Quasi-6th order bandpass to get some great spl out of my car, and i want to take it to the next level. I haven't decided if I want the g2 dynamics Genesys Series 15 or the DS18 Hooligan 15. If there's any parameters or info yall could give me, I'd gladly accept it. Yes, I know this type of build takes up space, and I'm ok with that. The dimensions I would prefer the box to fit in are : 44×22×34.25. However, the back of the box will be curved to accommodate my back glass, and I don't know how to calculate the box dementions given the curve, of cource if there wasn't said curve I'd have 17.2 cu³ of airspace. I also don't know how the 2 ports interact with eachother, I want to play low, like 20-45hz low, maybe even lower than 20 if that's possible.

I have about 3500W subw power. The alternator has 140A and I have a lead acid battery of 90Ah , do I need an extra battery? How big? Is it bad if I put another lead acid? Is there a formula? Thanks

I need help nailing down this port design, i have a customer coming in that im building a box for 6 Kicker Q class 10" subs running off 2 Arc Audio 2500.1s. The box needs to be around 16 cubic feet taking in recommended air space into account and ill be doing 2 ports tuned at 28hz for the lows. My issue is when i do the calculations my port length is super short and im worried i wont have enough port area for this much box. My idea right now is two slot ports 10H×6W but that only gives me about 7 inches of port length. Any help would be appreciated

Hey guys, up for sale I have my tight (well use your imagination)! You can also call or text me @ (717) 679- 6682. to see pics of what Im working with REAAAALLLY would prefer local hookups.

looking to purchase a term lab, good condition. let me know a price and what software it has. thank you.

Hey guys long time no speak, I know the ap30001d is 2 ohm stable, but ive heard they can run @ 1ohm safely with good electrical. Does anybody have any experience or know this to be true....running a dual 2ohm pap wmd2k 18 to it.. thanks again.

I just built a box for 4 12's but after doing so i started thinking about how to make it much louder, i want a lot of spl, my cars resonant frequency is 49htz would it be louder at like 34htz or if i made a box tuned at around 40htz?

Hi all im building a Passat 18T with 2x9515 DD woofers and 2xZ1DD amplifires i will post pictures as i go on wich me good luck in South Africa the loudest trunk car is 153DB http://www.facebook.com/pages/RadioActive-Car-Audio/284357928291938 HERE IS A FACEBOOK LINK TO MY SHOP PAGE I WILL ADD PICTURES THERE 2

the box has 22.86 cubes and 220 inches of port tuned to 35 hz. it will be in a 92 full size blazer subs up port up. port will be by back window. never built a spl box and need all input i can get.

So here's the deal guys, i've got room for 2 12's (but one higher quality one would be ok) and their corresponding box, the amp, and all the wiring. I need to know for about 1400 bucks what is the best complete setup combo(not powered subs , just individual components) that i can get for loud bass that still adds to sound quality. Anything you got would be fine, just need to know the subs and what to rms power them with all for 1400 bucks

Im sure many of you have read it already, but for those of you who havent here is an article sonic posted on their blog about SPL numbers and what devices are used to measure. common knowledge to most people on here but interesting nonetheless http://blog.sonicelectronix.com/news-on-the-car-audio-industry/ways-to-measure-spl/

i have been looking for a car audio competition for 2 years now. :WTFBubble:There hasn't been any,not even a hour way from me. Any one know of any upcoming competition in nyc or long island area.

Hey guys this is my friend Jeremys Hummer H2 I dont think he is on here so i thought I would share a vid of the setup my bf did for him. Enjoy

Well to start off here, my project is a 1986 Chevy Suburban. I picked this thing up and didn't really know what I wanted to do with it. Should I do a super clean build in it? demo build? showcase build? The options are endless but I've always wanted to build something original and loud. Once I got into this vehicle and really started digging in, I found quite a bit of problems with the floor. Some rust issues but nothing on the overall body that was too bad. Most of it was in the floor pan, which is quite common for this year but the overall body was in decent shape. There was a lot of past work on this vehicle and given all of it's wiring woes I wasn't sure I'd ever really trust it to drive down the road or be worthy of becoming a show truck. I decided to make it a demo vehicle, not built for strict spl but for fun. Something where I can showcase B2's product line in a platform that's a bit different and make it memorable. Some love it and some hate it. Some say how could you do that to a square body and some can't wait to see it get done. Floor will be fully steel to the B pillar with a full steel firewall and 7/8" thick plexi window. Full steel dash, full steel cage and probably 9-12 15's on 40-60k worth of power. I've never done a build log like this, but have always wanted to so here we go! (Also I am in no way a welder, and I know my shop is a disaster!) So here she was as I got it: This is kinda the idea for a box, but I'm up in the air. Have to deal with the tubs as well, so my options are a bit limited due to space. Looks pretty clean on the outside but she's got some issues deep down. The wiring on this vehicle is beyond a joke.. but we will get to that later. She's got a 5.7L 350 TBI swap from a 94 Silverado based on what I can find. The ECM and wiring was very poorly done here and left me with no choice other than to pull it all out and fix it. I can't even describe how bad the wiring is, a lot of it I couldn't even bring myself to take pictures of, just needed to get it out and start over. I also found that the harness for the ECM was cut in the middle at some point, and just twisted back together and taped. Like who does that? So out with it and time to get into fixing it. This was extremely painstaking to find out what goes where, what's been modified and who knows what else. So this wiring is ongoing, I'll get some progress updates on it later as it's still not completely done. Stripped the whole interior out. Air Suspension: I replaced the front and rear bags. Added two compressors, a new tank and managed to salvage the valves that were in use on this before hand. Don't have any pics of it yet but I'll get to them. The window: This is where it was to start with. She's got some rust in the lower corners and I had to CUT the dash out. On these models they are welded to the window/firewall frame. I've never built a SPL windshield before. I had some ideas to go off of and decided just to go for it. I know I wanted a split setup and not just a straight tank looking windows. After a lot of thought I decided to just go with something like this. Spotted her up and started moving forward. Made some side bars and got it mocked up a bit more. The goal here is to have two pieces of plexi that are flat, as getting it rounded or curved so to speak would take a miracle. The outer bars taper in a bit, and I did this so I had ample room to make some epic A pillar pods. There's almost no room from factory to put anything in the A pillar without it sticking WAY out. The sides will be welded flush with some sheet metal to clean it up. Started cutting out the floor. Oh boy this has been fun. Just as a side reference. Chevy didn't want this to come out lol and it really didn't want to. It's a major pain in the ass but well it is what it is.

In Stock And Ready To Go, Now Whos ready to GET LOUD!!

I merged 2 threads and things got a little screwed up lol So I added Johns first post to his right here : This is the official thread for the Tahoe build off we hope you enjoy these builds as much as we do! So we are doing a little friendly competition between Sky High and DC Audio. A few things fell into place and we ended up having GM SUVS dropped off at the same time so we decided to make some fun out of it. Rusty, his team, and DC Audios build will consist of the DC Audio Yukon 4 M1 LVL 6 18s with the aluminum baskets. 4 DC Audio 5Ks and a B pillar wall; just to name a few things. The Sky High's Tahoe will have 6 Lvl 6 m2 18s with aluminum cone and 4 DC 10ks in a B pillar wall. Rusty and I (Jon) will be both posting pics along the road to crushing every other Tahoe on the west coast. DC Audio and Sky High have a pretty good and close knit relationship if you guys did not know. This is a friendly build and we are only out to have fun and get some recognition out there for the amazing products going into the builds. So please enjoy the builds and your input is greatly appreciated. See you at Lake County Car Audio with both these builds for the finale!! And Mine starts here - So Alot of you might remember the DC Yukon, Well its at the shop and were going to wall it. Not 100% sure what the plan is but for right now I just removed everything so i can start to measure out the shell. its got for gear (well before I took it all out) (2) 175.4 (4) 5.0 (4) M1 Lv6's (2) Alts (2) Strong Stinger 2150's, The rest of the 2150s are dead and will need to be replaced. The Yukon sat for a while and the battery's are now toast So Im not sure if it will go flat wall, clam shell, 4th order, 6th order. Part of it will depend on the square footage we end up with. On with pics of my progress today

I got a pair of Massive Audio DC 10's and i was wondering if anyone could help me with a box design. I want a box good for SPL as well as a decent daily box. Preferably Tuned in the lower to mid 30's or higher if i can still play into the 20's. I mainly listen to decaf and big pimpin. Thanx.
