i need a btl fully loaded d2 18 recone (w/ old style motor) if anyone can help plz let me know

I was planning on getting a 15" ssd for my 95 saturn sl2....the problm is my trunk isnt the biggest. I have enough room to make it the recommended 3-4 cubic foot box but i would have to face the sub towards the top of my trunk. If i did this would it still sound as good as if it was facing the back of the trunk, and where would I have my port facing. Can anyone possibly make me a box design that would fit in my trunk for the 15" SSD. the trunk is about 15" tall, wheel well to wheel well is about 35" and back to front im not to sure. I would greatl appreciate some help on this. I was also planning on running my Us amps xt2000D on it.

Hi, need some blueprints for my 15 inch fi btl fully loaded. it is feeded with aprox. 3 kw. the enclosure is used for spl competitions only, perhabs a flared port is the better choice. The woofer is going in a 1990 volkswagen golf mk2 and the car peaks at 52-55 hz. I'm of course ready to pay for the blueprint. The max width is 37 inch, feel free to the rest, it doesnt matter. Please email or pm me or just post in here Patrick :-)

Hi, have my new car since a few days now, a 08 BMW 330xd :bigclap: :bigclap: :bigclap: But this time i just want a lil boombox in the panel of my trunk. I just ordered a 10 inch Fi SSD Dual 2 Ohms today and expect it by the end of the week... I wanna put it in a sealed enclosured like this finished looks like this I measured about 0.5-0.6 cu ft What you think, will this work fine?? And it gets about 900 RMS

Hey team well i got a deal cheap on a btl fl , and usps dropped and part of the basket broke. Can it be replaced?is it hard? Will fi car audio sell the basket alone?

i did some measuring and the biggest i can go is 4.5 or less.. so ill have to get a bl 15 instead of the 18 that i had planned.. and i plann on getting a hifonics 1606. box tuned to 32. what you guys think. should i get any of the options. heres the box i got http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0

Not at the same time! I have two boxes built for my single 12BL. (D2, loaded, daily) One is 2.5cuft @ 32. Slot port. Homemade The other is 2.0cuft @ 32. Kerfed port. PTS They are both designed around the 12BL t/a parameters. Two questions. Is the BTL a substantial upgrade from the BL? Could I use the 12BTL in the same box which was designed for the 12BL?

Will somebody please explain to me where the length of the port is. In order for my box to be tuned to 32Hz it has to be 22.5" long but which piece of the box is it? is it C or B?

hey all im really sold on getting a bl 15 for my car. i was just wondering how much it will cost to get it shipped to montreal since it states on the fi site that shipping only free in the states. im also wondering if the flatwind coil is good to get if i plan to use the sub daily (will it give much better sound).

Hey all, bought a 15" Q last night to mess around with and have some questions. Recommended enclosure is 2.8 to 4 cubes and tuning anywhere from 28 to 33. I need to figure out where in that range I should build. I listen to mostly metal, rock, blues/folk and on the rare occasion I'll crank some old school hip hop. I know kick drum is front stage and I will get flamed for this but I still like cutting my subs at 80 to get some impact for kicks out of them. I have a Kicker sx1250.1 that will be going on the Q so it will be just a bit over the rated limit of the woofer. It will be going in the back of my 07 extended cab F150. I toyed with the idea of going sealed but I …

Hey guys! I was wondering what any of you with a Q 18 set your crossover or lpf to? Also what type of crossover? Right now I have BW and LR filters to choose from, 6, 12, 18, or 24db/octave and 12 and 24db/octave, respectively. A simple frequency recommendation would be great though, hehe. I have tried many values from 70 to 180Hz but can't really decide. Are there any tests I could do to help me decide? Right now I have it at 127Hz 24dB LR which seems to be fine but I still feel indecisive. Thanks!

i have an 04 honda accord sedan which im going to put a Fi Audio 15" Q Sealed Box sorry i dont have trunk dimensions... what do you guys think will i have any problems? Design me a box! anyone pleaz

is it ok to trace around the inner black gasket ring that comes with the subwoofer to get the size for the cut out hole?

do anyone know what the prices will be to recone an ssd 12 2dvc Flatwind Coil?

Ok guys I need a little input on a few things. First off, I was running two FI Q 15's off of a 40.1 @ 1 ohm in a 8cuft box ported to 28hz and blew one to hell and the other one's coil is burnt like a motha... So I was thinking of going with either one 18 BTL or two 15 BTL's off of the 40.1 @ 1 ohm. What do you think? Either setup will be tuned to 32hz. I was planning on modifying the current box if I go the 15 route, but if I go with the 18, the box will be around 7.5~8 cuft tuned to 32hz. This will be a daily driver setup.

hello i have a fi btl 18 triple stack im looking to put in the back of a ranger is there anyone who could help design a box i have the top dimension to be 12 and bottom dimention to be 21 and the width no longer than 48 and heigh how ever long it needs to be id like i tuned to be loud as possible lol please pm if you can help

Any thoughts or ideas on 2 12" FI BTL's (Fully Loaded) in 5 ft^3 with almost 154 in of port area????? Tuned at 32 hertz.... I understand that it is going to be an extremly long port almost 71 inches. but i have ideas for that.....Planned on using 14 inch round pvc pipe with a few 90 degree elbows in it. and how would u go about measuring something that has that many bends. Also i planned on the port having its own chamber with only the end into the part of the box where the subs are to reduce flexing and hopefully where more air flow goes into the port. But it might be a crazy idea. So if anyone could give me some feed back it would be great!!!! Thank's, Brock

Ive got 2 BTL 15s and i wanted to make sure my calculations were correct before i started building. The total room i have to work with is h=23 w=24 l=39inches. Total internal volume is 10.5 cubes, and after all displacements i have 8.65 cubes. the port dimensions are h=22.5 w=4.5 l=18.4 which should make the box tuned to 33hz. can someone check this for me to make sure i didnt make any errors. Thanks Keith

Like title says........what is the recomended port area for an X 10? It will be in .75cuft using aero port...............I'm thinking I read a 2.5" was enough once just need confirmation.

I'm thinking about a having a box with the subs facing inside the car right behind the rear seats. I'm a bit worried though that the subs might hit the seats if it's not far enough. Any idea what would be a good distance? The subs are 12" Qs.

I'm new to the forums and i was interested in purchasing a 15 inch bl and running it in a ported box for loud bass. I'm not into competitions or anything like that i just like loud music. I've been watching videos on youtube and the realm of excursion and i think these subs are badass. Now to my question, if i purchased one fully loaded 15 inch bl how many watts could i put into it and be able to pound everyday in a daily driver without blowing it and which amp or amps would be best for it?

I am new to car audio and need some help with what i would need for a subs as powerful as the BTL's. I heard you need a charging system for your amp to keep up with it, but im not sure what that is. Also what kind of amp would i need for, lets say 2 15" BTL's

I'm currently looking at components to go with my 12" BL. I'm going to either go with Rainbow SLC 265s or SLC 265 Kicks. What I was wondering was with my box tuned to 32 Hz would my BL get loud enough up to 80 Hz to be able to have my high pass at 80 for the Kicks? Thanks

Ok go easy on me fellas. For the past 4 or 5 months my Bl 18 has been in a wooden box without paint or any covering. So Saturday I decided to paint my box. So I painted the box black. Then I wanted to get creative. So I chose my colors to be black and gold. I tried to paint my dustcap but I messed up and now I need another one, but I was wondering if I could get my new dust cap in my custom color. Now this is a thread made for helping not talking down on. My sub works fine the dust cap just looks like crap. Oh yeah I already admitted my mistake and learned from it. Please offer advise and don't state the obvious.

Would you guys suggest tuning a BL 15" to 28hz? Has anyone tuned their box for one that low?
