need some help to come up with net volume and frequency for this sub. my friend will be running 2 of them in a blowthru and space is not an issue. the gray line is the rsdc (2 of them) with 1200rms, the red is 2 12" AA arsenals w/ 600 rms, and the orange is 2 12" l7s with 1200rms you can get the specs from the image if you like pg recommended, according to someone on pheonixphorum.com, specs for ported are 2.5 cubes per sub tuned at 23.28 hz. (spl secs are .8 cubes and tuned very high... like 50 hz iirc...) as you can see i bumbed it up to 24.5hz. but i still think this looks very low. i also notice you run out of xmax @ 600rms per sub.

so in my blazer my current setup right now is 4 p3 fosgate 12s on one sundown 3500. my box is a little under 8 cuft tuned to 37ish hz. my score was a 147.2 and it peaked at 46hz. I'm fairly pleased with what it did considering when we clamped the amp for my second run, I did the same score but the amp was only doing 1863 watts!? I'm pretty sure that my alt might have something wrong with it that's why the power wasn't there. well what do you guys thiink? is it a respectable score?

I have decided that I am open to trying a 6th order blowthrough for my XCON and will pay someone to design something for it. I currently am doing a ported box with a small adaptor over the front to channel it in through the ski-port but have been reccomended to just try a 6th or 4th order, I love the sound of 4th orders but the XCON is not so suited for that so a 6th order would be the go here. I am after a response resonably flat between 28hz and 50hz or so and the port has to exit pretty much central to the width of the box. The port can be external by 80mm at the top and about 110mm at the bottom and have max dimensions of W:320mm X H: 185mm (Internal Dimensions)…

Where can I find some test tones from 20-30hz. I have the 20 hzand 30hz test tones from ROE, but I want all the inbetween (21, 22, 23, etc...) Can some one help me? This is for my HT sub system. Thanks!!!

Lately I've been looking into Fibeglass subwoofer enclosures and I'm just wondering if they function any differently then an MDF enclosure? I've done some research and wouldn't think it would affect the sound if it was properly constructed but alot of people online have said that MDF is the way to go. Is that just because MDF is so much easier to work with or does fiberglass really affect the output of the woofer? Also, after looking around the site alot of people here use fiberglass for speakers and midbass drivers but not many use it for Subs and that got me worrying about it too. If any of the Guru's here could shed some light on the subject it would be greatly appreci…

Hey, I just bought a whole bunch of twisted speaker wire for my install. 8-16AWG http://www.knukonceptz.com/productMaster.c...Speaker%20Kable I have no idea how I splice it to be able to attach female disconnects or screw the individual wire into adapters.

Due to my inability to use the SSA search feature (i'm guessing it's the school computers) could anyone either post a link to another thread, or a simple diagram on how to do so? *the tech guy at our school screwed up yesterday and programmed all sites not relating to school stuff (search engines too, once an non related search was given) to be locked automatically . it turned out his parameters were much too vague . He is untangling it now, or i woulda used google.

Can you guys recommend some really good affordable e.q.s to me that you really like?

ok so i was just browsing some older topics today and realized that i have a wire kinda out of whack. im not sure if it is hurting or helping me or if it even has any effect at all. the blue wire (line) in the pic is the wire im referring to. its from my alternator negative to the negative on my second battery in the back. i have no idea what was going through my mind when i hooked it up like this but if im not mistaken, isnt it doing the same thing as if it were the negative on my battery up front to my battery in the back? also, one of my other questions was should i be running a power wire from the + on my alt to the + on my batteries in the back?? the way the pic is i…

I gotta go run and pay insurance.....that's all i got for now! Brb

Love the look of the boxes how to I go about ordering one ?

i have multiple questions. 1) i have two MMats 15 P3.0 . that can take 700 rms each. What amp should i use to push these? 2) i have a big custom box tuned to 30 hz . it doesnt fit in my trunk so i will be having them on my rear seat(tightly secured down) should i have them facing the roof or the front of the car? and how will it sound? thank you for everyones help. im a newbie.

OK. so I am just about decided on the new sub project. I have a jeep cherokee, with (2)mb quart qsd 6" sets, running of off an orion 8004. I have a optima yellow top under the hood, but stock alt, and wires from alt to bat. I want.... to run two 15" havocs off of a Orion 2500D. I'm going to run 1/0 under the hood, and to amp. and get ho alt. my questions are... #1. How big of an alt. do i really need, as anything over 240-250A gets spendy. #2. How many/what kind of battery's should I put next to the 2500d? optima? kinetic? #3. Are batcap's worth a damn(once again, mixed reviews)...? I have heard mixed reviews about the optima's, but Ive had mine for almost a year n…

I have the chance to buy an orion hcca d2400. The guy says it keeps blowing fuses. I'm thinking the power supply is shot. Can anyone give me a rough estimate as to what db-r charges for this sort of repair. I put in a request but haven't heard anything back yet.

I'm thinking about buying an RLP 15" for my home audio needs. I've always wanted to try SS audio and just haven't gotten around to it but what better way then HT! My question is how much power does this thing need to sound good in an HT setup? I read from a different thread that anywhere from 2.0^3's to 4.0^3's tuned from 17hz to 20hz will be best so within that range of box specs, how much power will it need?

I'm in some serious need of more deadener. I have decided, for the most part, on RAAMmat BXT. I'm just not sure if I should pair it with the ensolite or not. I'm sure it will help, but would it be worth the extra money (limited budget for now)? My main concern is the roof by the way. Thanks in advance for all suggestions and advice.

What are some Mp3 players that get fairly loud while retaining sound quality? My iPod Video with Rockbox OS was the best i've seen, my classic just doesnt compare

I live in baton rouge and wanna get metered. There is a shop in Denham Springs that charges $10 per run to get metered. Does anybody own a term lab or some other spl meter and wanna help me get some input on what my system can do? Thanks guys

89' CRX, unmolested, pretty clean, came on 17" enkei shoguns, was a 50 yr old ladies car , very clean inside. Great base to start from, no fast and the furios crap will be bolted on to this.. But It will have a ALpin 7949 deck, 2 tc 3hp/FI 12" subs, on a AMerican bass xd3000. And a set of the Lanzar Opti6c comps on my old school Sony xm-5046.. should be a great project

I ask because i dont have heavy basd till volume 20-23/25max Gain is 24v at volume 25 I may try it out because i have s clipping indicator

Im currently running an icon 12 in a 2 cu ft ported enclosure tuned to 32 hz on a sundown sae 1200 v2 @ 1 ohm. I had a pair of fi ssds (d1s) before this, but i only ran one. when i bought the icon, i sold my friend one of the ssds and planned to throw the other in my gfs car but i never got around to it. well my friend has had the ssd for almost 2 maybe 3 months ago (has not used it) and text me the other day and asked if i knew anyone that would want to buy it ($100...i sold it to him for 125). so im kind of thinking about buying it back. the amp i have for my gfs car is a rd 1000 v1 amp (ik not the most favorable company, but ive had the amp for 5ish years and not a pro…

I changed up the design on my towers, so I don't have a place to mount / hide the crossovers. The initial design called for them to be placed inside of the cabinets ... in the upper section with the 5.25's and tweets. However, I scrapped that idea to gain more internal volume and pushed the 'back' all the way back so it's flush with the back of the bottom section (think of one solid back ... mind you, I'm sure you've seen the pictures, so no need for me to explain it). Anyway. I need to mount the crossover components on something. I'm not all for a piece of cardboard duct taped to the top or rear. I was thinking of mounting the completed piece to the top each tower, wh…
