Fi Technical

Hey guys , i want to build an sq box for my FI BL 10 ! I hope you can help me with the port an the size of the box ! Thanks for helping me ! Nice regards

okay so i have an old three stack magnet btl twelve if i bought a new single stack btl 12 would it be worth it thanks.

I have a 2006 Nissan Sentra (1.8L) that has the stock alternator putting out 80 amps. I am looking to soon be running 1200 watts RMS through the system. I know I will have to do SOMETHING with the electrical system. But what? New alternator? Extra battery? (Big three is a given) If new alternator, would the one in the link below be suffice? (20 extra amps) http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=120530973171&viewitem=&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2&category=33573

Since both the Fi BL 12 and BL 15 are 1000 watts RMS, and I have about 1200 watts to play with, which should I get? Would there be a huge difference? And on a completely unrelated note, how do you guys go about bolting down your enclosures in your trunk? I have a 06 Sentra and below the carpet in the trunk is the spare with a piece of cardboard over it. Now there is about a foot of exposed metal running down both sides of the trunk. Just curious about how it's done. *Guess I should have asked first, will a box for a 15" BL fit in the trunk of a Sentra? Thanks.

I'm seriously considering getting a Fi BL 12 and was wondering if the amp I link to below this would still be a good choice. Thanks in advance. http://www.db-r.com/sell/store2/index.php?main_page=product_info&cPath=65_67_69_105&products_id=248

i have two fully loaded 18 inch btls dual 1 ohm and one sundown 3500d for now not to sure on the way to wire them... preety much a noob when it comes to wiring subs....my guess is since that i bought dual 1 ohms i will only be able to run them at 2 ohms or .5 ohms if u guys could let me know if this is correct and maybe throw a picture up on how i should wire them that would be great thanks guys

I found this box on woofersetc.com the dimensions are: * 12" Single Ported Box * Height: 15" * Width: 30.5" * Depth: 15" * Mounting Depth: 11" * 3/4" MDF Construction * Volume: 3.00 cu. ft. And I wanted to know if this would be a good box for the fully loaded 12" BTL sub? Thanks for any responses.

So i just ordered my 15" BL sub, and im getting it soon and cant wait, but im kind of stuck on what amp to run it off. I was looking at the Kicker ZX 1500 amp, using all Monster cables to power it. however, before i spend my money on this amp, i want to be sure that it will be the right amp? is there any other amp that could be better for me to get around the same price as the kicker amp? i rlly want my sub to pound, but sound good at the same time. thanks alot to anyone who helps me out

ok, well i have truely made up my mind and will be going with the Fi Q 12". my question is, will this box be good for the sub i.e. enough room for the sub to "breathe"? Box specs: Depth: 11 Width: 30 Height: 16 CuFT: 2.27

Hi all, I just recently switched my Q10 from being sealed in an ext. cab S10 to .9cuft port enclosure in an '88 BMW 325ix. I took a ton of time designing the box for the bimmer because I was looking for more output down low so I shot for 27hz using 4in PVC. I got it all built up and installed and I'm slightly disappointed with it so far. Things just don't seem loud enough. I figured going ported AND in a larger cab compared to the S10 I would get more output but I'm getting significantly less. I must add, the enclosure is sealed up to the rear firewall firing into the cabin of the car through the ski pass hole so I have zero trunk rattle. I don't know how this would affec…

my max dimensions are W:40: H: 14 or so D: 20 freq wanted. : 32. Daily driver. could someone help me our, or is my height screwing me over?

I'm looking into getting an Fi Q 15" subwoofer. I want a great SQ sub so I figured this was the way to go, but now I have a dilemma. I'm not sure if I should get the high QTS or not, I know I'm probably going to put it in a sealed enclosure, but I'm worried, if that isn't right for me. If I change my mind in the future and decide to go ported, is the high qts going to be a problem? Thanks.

What are some optimal dimensions for a box for a Fi BL 15. I really want "SQL". Need to know how many drivers port area port length tuning frequency. (W x H x D) Thanks for the help.

Hey guys, I'm pretty new to the car audio world, being that I'm only 16. But I have worked all summer and have finally saved up enough for my first system. I want to get a 12" Q and I want to build my own box but I want to get it all planned out before I start ordering everything. I have designed up a ported box that is 25"x20.25"x14.625" and is tuned to 32 Hz and has a net internal volume of 2.2 cubic feet. My question is how much bracing do I need to use and I know that it will reduce the volume, but what will that do to the frequency of the box?

I'm going back & forth between using 2 15" IB3's & 1 18" IB3, but am a little concerned about their output between 50-80hz. I'm going to use 8" pro audio midbass in my doors, but from what I've read they shouldn't be crossed lower than 80hz. Does anyone have any input they can give me on the IB3 line playing these higher frequencies?

Anyone here running about 140 db on a single Fi Q12? What amp and size of box did you use?

I am running a kicker 1500.1 and a dual 1 ohm 15'' bl from my factory nav/cd player in 05 escalade using a audio control epicenter plus and was told that my kicker amp does NOT have subsonic filtering for the sub PLEASE what do I do? Also my box is 4.00ft.^3, port area 56.00in.^2, and tuned at 30hz

So i just got my dual 2 ohm 15 inch BTL fully loaded and I am going to run a 2100 hifonics amp to power it. So today i go to my local car audio shop so they can install it for me and they said that they can only wire it down to 3 ohm or .75 ohm because the voice coils are 1.4 ohm each...However, everyone else on this forum says they are running their 2 ohm Fi sub down to 1 ohm. I am a complete car audio noob so if someone could please tell me if this is true or not i would greatly appreciate it. Thank you!

Robin (iamamp3pimp) was in the process of building me a 2.8^3 @ 35Hz box for my AA Chaos 15D2 when I had to sell the sub due to financial issues. My question is would a Fi BL15D2 run off my AP15001D work in this enclosure? Sub would have cooling, flatwind, and daily options. Looking to get decent lows and numbers out of this box, though sound is more important than numbers to me. Had the CHaos 15 in a similar box before with good results, just bumped up tuning on this new box from 30 to 35Hz trying to get a little better score than the 143.7 at 40Hz I got with the first box. Here is a pic of the first box, new box will be designed the same but built out of raw birch. Th…

I just got my BL in the mail from Joseh K. and USPS has fucked my basket UPPPP Could this be fixed my some very careful welding? I mean what else is there to do with it.....

hello I would like a design for a single with dimensions of 17H, 40W , & 18D Mmaybe alll the WAY to 22 but sub will be to close to trunk wall ... on you tube thers a design double port the guy has It on a civic very nice.oh and tuned to 33 to 35

here is waht i have to work with... 11" tall, but that doesnt leave much excursion room, so maybe 10"? 32" length 16" deep im thinkin about a SSD 10 or 12 ... idk if 12 can make it in the space... woofer should face sides front or top, probably a must that its on top anyways because of hieght limitations.. i want to only be able to see the carpeting, no components or sub showing.. will be 500rms for now, ill get a 1000 sundown soon enough.. its for a 63 impala.. so help me on ideas friends.. thanks!

ok i plan on running 2 SSD 12's off a AQ1200D @ 1 ohm. the box it gonna be roughly 4.4 cubes depending on how much the aeros take up for space. what would you guys suggest for aero size? i know i would need less port area for aeros then say a slot port but im not sure how much less i can use. i was thinking 1 6" aero which would give me 28 sq inches of port area (6.27 per cube) or i was thinking of going with 3 4" aeros which would give me 37 sq inches of port area (8.69 per cube) now i know thats less then the recommended port area for slot ports but i was wondering if either of those would be acceptable for aero ports.

Curious if anyone wanted to help me out by designing me a box for my 2 18" bl's. i want to build it myself for the experience, but dont trust myself designing a box. Obviously new 2 this, if interested i can give u max dimensions and other info for my 98 tahoe. Im plannin ahead and not ready to build box yet, but just would like to find some1 to help me out. Thnx for the responses.

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?
