is there a certain distance the driver wants to be from the back of the enclosure or is it fine anywhere as long as the correct amount of volume inside the box is present? also, is there any advantage to buying a dual voice coil sub over a single voice coil?

Hey i have a Fi BL 15" and i was wondering for my amp kit do i need to upgrade it. i havent yet to install the sub yet cause im scared my 4guage rockford amp kit wont handle the sub and might jack it up..will it..or do i need a 1/0 amp kit?? will a 4guage work or should i rip out the 4 guage? and if i need a 1/0 can i keep the existing ground cable and remote wire or do i need to change those out to?? thanks..and sorry for so many questions!!! -Ryan

Here is a photography project I did titled "Speakers of Nature." The idea was that the speakers I use in my car have been applied to nature to contrast the uncanny replication of sound that speakers can make to that of something so natural sounding that you would never have known it to be replicated in the first place. Anyways, that was the idea and from there I used everyday tools that just about every car audio enthusiast has to create this project. I will post the pictures in order from cover to cover. Thanks for looking! Ps. Sorry for the quality of the images but I didn't want anyone copying my work. But feel free to use my ideas, just don't claim it as …

Hi, im jay, i was wondering about the SSD15, I noticed it is 800W RMS if i wired it @ dual 2 ohm to make it 4, AND put it on a [XLS crown802] which would give it 800W@4ohm perchannel, and 2100@4 bridged, Do you think it could power it? and if so how about 2 of em from the bridged? thank you and please respond respnd back if possible! Also what would i need to tune it to to listen to NUTTIN but low, around 28-32herts? thx! -jay

I haven't been able to personally see a FI dust cap, but is there a way to change the color to something not offered by FI? Is it possible to just take some paint and paint over the white version with the color I want?

i gest orded my first btl 18 im going to put in 8cuft box tuned to 30hz fith a usamps2000hc to it what do btl users thank

I'm gonna be ordering 2 of the Q15's dual 2 ohms fully loaded, and wiring them both to a AQ2200D, and I want to know what would be the best enclosure I can build for SQ? I've heard sealed is the best for SQ, and aside from that the carpenter building the box for me doesn't know anything about tuning a box, so i'm pretty sure ported or bandpass is out of the question. Would I be right to assume if I use the max 4^3 feet per woofer it would hit the deep note better? If so, what would be the best way to put both of those into a 43inx40inx17 (LengthXWidthxDepth). I believe i'm gonna mount them from the top unless someone could provide a good option that would allow for otherw…

Hi! Someone knows where i can buy the fi woofers in germany?! I send some mails to fi caraudio but i get no answer :-(. Dear Amateur

ok so i got tired of bumping the other thread and not being answered. I have the quantum view tracking number, received on the 24th, according to ups would have been delivered on the 28th. it's now the 30th and it hasn't been sent out yet. can someone possibly check it out and see where my package is. I'd love that. thank you very much!!!

I decided to change the "sub-stage" in my truck from that single 15" in that ported enclosure that just never seemed to sound right to two Fi Q 12" in a dual chambered sealed enclosure. The enclosure has about 1.5ft^3 per chamber. The two subwoofers are without the BP option and are being powered by an AQ2200d amplifier.(2200watts@1-Ohms). Hopefully sending each Q with around 1100watts. The subwoofers are DVC 1-Ohm, wired in series to 2-Ohms per subwoofer and bringing a 1-Ohm load on the amplifier. The first Fi Q 12" has been bought and so has the AQ2200d. I plan to order the second Fi Q in a week. What influenced my decision for this subwoofer stage: 1. The Q's performa…

In order to get a ported box just perfect could you just punch in your cubic feet what you are needing in your box, then get the port dimensions and figure up the displacement of this inside of your box and add in sub woofer displacement. After I add these up could I enter my Height, Top and Bottom depth, then using my length as my variable to figure up how many cubic feet I need? In other words say that I have a sub woofer that has a displacement of .11. Then i figure up a port that would displace .2 cubic feet in a box. I'm needing 1.2 cubic feet after sub and port displacement. So the box should be 1.31 cubic feet inside? Here are my two designs http://img.photobucket.…

Is there somewhere i can get a tracking number for my sub i ordered like 4 days ago?

After watching some youtube videos of some fi's I heard a lot about stock electronics and what not. I am getting a 15" Bl and will power it with a Hifonics 1200 or 1600, and am wondering what "electronics" i will need so that I don't wreck my system/car.

Hey I'm buying one of these for my home audio and was wondering if I blew it could FI recone it with softparts more car audio oriented? it has a sexy lil neo motor and basket on it and a 3" coil Sexy lil beast

okay guys, i am fairly new to the whole subwoofer thing and i need a bit of help getting myself started. First off, i need to know the differences between duals (1) (2) (4). My friend is helping me with most of this, and he tells me that i need subwoofers that come in a dual 4 ohm coil so he can wire them up to 1 ohm. I am planning on getting 2 12" Subwoofers, either Soundsplinters rl-p in a dual 4 ohm (if i knew what that meant) or the Fi Q's, but i'm having a hard time figuring out if they can be wired up to 1 ohm. Whether i get the rl-p's or q's they will be both placed in the same exact sealed enclosure, and will be wired to an elemental designs amp that is running 12…

Hey guys, ok so I bought a 12 ssd with the copper coil option and Im going to be running it off the Kicker zx1000.1 amp im putting it in a 2008 nissan frontier extended cab and i was wondering what you guys think would be the best box dimensions for both ported and sealed enclosures I am building the box my self and i just wanted the deepest lowest bass with the SQ Thanks

i have a maximum of 42" wide x 12" high x 19.25" deep i can use keeping everything else stock. The amps will be mounted on top of the box but an extra Kinetik battery in the back WILL take up some of this box room. After some calculations, i came up with 2.8-3.0cuft NET after displacements for the 2 following setups- 3 10" Fi Qs SEALED off of 4,000w or... 2 10" Fi BLs PORTED at 34hz off of 3,000w I wish i could do 12s but i do not think subs and port up would sound good. PS- i dont have room to do 12s unless i aim them up and can only do them if i port up as well...i have no boxes to test how that would sound either...)

2 10" SSD's off of 1200 watts, any benefit to adding BP power to them besides that i could add more power later? would it make the subs to stiff? would they not be as loud? would the add'ed cooling and spider make the sub's last longer? thank you for your time and, i hit 142.* with my 15" Q in a 2.8 cuft aero port box. it makes me happy wile sounding great. *bad white boy dance*

im looking to change my setup. if i go the bl route, my box cuft will be 5-5.4cuft total including port area. if i go btl route, the box will be about the same total. they will be powered by a zx2500 which in the birth certificate says 2700 (if that matters) now i want to know which will be louder. this will be for daily use in my dodge charger. i currently have 2-15" L7's sealed in a 4.2cuft box and it pounds, but i just want to change it up. plus, i have a feeling that i can get louder than it if i go the FI route. thanx im also open to other suggestions.

Can you guys at Fi build passive radiators that have stupid amounts of displacement on a 12 or 15" frame? I can get some 18's, but they're too tall for my purposes (I think). I don't have my new car yet, so I'm attempting to draw out something insanely different

ok so today i was on my way home and my sub just quit working. i checked the ohms for the coils and its 1.25 . i checked the wire running from the box (there wired to one ohm). So i thought that it was ok. so i then checked the voltage of the speaker wiring coming from the amp and the volts were jumping up and down. so i then hooked up a ten and it played fine. So my question is what is wrong thanks for the help. my amp is sundown audio 2000d my sub is fi btl12 MY HEADUNIT IS pioneer avic n4

i am gettin a 15" dual 2ohm Fi Q i want to know if it would sound better ported or sealed thanks

I am hoping that scott or nick can help me with this...i sent an e-mail and i know you guys are busy, but i have not gotten a response yet so i'll reort to the forum again... i need a dust cap...the outer one...i have my speaker reassembled and this is the last piece of the puzzle...i was wondering if i could buy one preferable a blank one....is this at all possible scott or nick? thanks for the time

A year or so ago, I sent a Crossfire XT motor into Scott for a recone and he was unable to find a coil that would work for daily bumping. Anyhow, I ended up purchasing two BL's that same week and basically told Scott whatever on finding a coil for the XT motor. So my question is; Where is that motor now? lol Let me know if Scott still has it, because I wants it! Thanks, Matt

I have a 15Q and i made a box for it. The box is 3.146 cubic feet. I have two 3" tube ports and i need to know how long they need to be to achieve a tuning of around 33-35 hz. Thank you in advance.
