Fi Technical

I know no one probably knows really for the 09 lineup but would the BL 15 really get THAT much louder than the 12 if they were both fully loaded? Or would it be a noticeable difference? I want to know if it's worth waiting however much longer for the 15, or if i should just order the fudgeing 12 cuz im sick of waiting lol.

Just wondering if someone could give me some plans for a ported box. Nick told me to post here and someone would be able to help me.... sub - Fi Q12 amp - TXA 1000-D max dimensions: -Height - 16" -Depth - 18" -Width - 36" Thanks, Ryan

Just ordered my 15" SSD and cant wait for it to arrive. Now on to buying an amp for this little beast. It will be going into a 2008 Nissan Frontier 4.0L V6, enclosed in a 4.2cf. Ground Shaker box. My main concern is how much this sub can handle. Its the Dual 1 Ohm version along the flat wind coil option which Ive heard ups the power handling. Ive been looking around for an amp, Was looking at the Kicker zx1000.1 which puts out about 1100-1200W RMS, the MTX Xthunder X1000D, and the Alpine MRP M1000 all puting out similar rms W (1000-1200). I would like to go with the MTX for the reason that it is on sale for $269 on sonic. Ill include a product list below along with the mo…

hi i wanted to know if there is a downside to using an N2 recone on a ufo btl, because i have a friend with 2 recones and have no use for them and i needed recone. would they work?

I am wanting to know if these numbers are sufficient for a vented enclosure for for a 12" BL. I will have it hooked up to a MTX TA81001 A 1 ohm in the trunk of my 06 Honda Civic. Any suggestions would be greatly appreciated.

Hey guys i have a 2009 silverado crew cab. i asked a few weeks ago how to get more bass out of my truck a few of you guys suggested raising my seats to accomadate larger subs and enclosure. that being said i raised my seats 4 inches. i now 3.8 cubes before any displacments. my questions are im looking for the best spl but i dont think ill have enough space for two 12 btls if i port the box. the box is 55 inches long and a port is gonna take too much space. the subs will be firing down into fatmat so i dont think im gonna hear much "music" out of them. any suggestions? thanks

I was driving around and all of a sudden my btl quit. I have tried to rewire it using just one voic coil and noluck it wont even turn on... Any idea?

Wheres the BP option when buying the 12 SSD? Is it not offered any more?

Hey I tried doing a search...I kept getting an error anyone know the specs on a TC7 motor?? I am probably going to buy one because of a good deal on it. What size coil does it fit?? Will a standard 12 spoke basket fit it???

I just built a new enclosure and was wondering if 118 inches of port tuned around 31hz ok for my 4 fully loaded BL 12's?

DO SSD 15 WORK SEALED I HAVE2 AND I WANT 2 GO SEALED HAS ANYONE TRIED THEM IN A SEALED ENCLOSURE YET? WHAT WOULD BE A GOOD AMP FOR THE PAIR

Im ordering a 15 Q soon and am going to start on my box for it. I was messing with re box calculator and having a few problems getting the right size, i have limited space in the trunk of my civic. I am going to run it ported at around 32hz and would like to get as much cubic feet as i can out of my trunk, any help would be appreciated. Box can not be wider than 34 inches, can not be taller than 16 inches, and can not be deeper than 18 inches, any help would be a appreciated. The cubic feet part is easy to me but the whole port part and how long the port should be is confusing to me. thanks Also on the re box calculator site which number do i use to figure out the 12-16 s…

I just hooked up my brand new fi ssd 12 dual 1 ohm sub and hooked it up to a kicker zx750.1 amp and put it in a 2.5 cu ft box tuned to 33 hz. i turned the gain 1/2 way and bass boost to 9db. When i turn the head unit up the sub starts to smell like its burning glue or something. any ideas?

Got my car back from the dealer service dept. and my 10" rockford T2 was fried. Rockford doesn't offer a recone and the parts distributor that they referred me to says they have a really long back order on parts. I was wondering if it's possible to do anything with it? It was a pretty decent driver, and i would hate to just throw it away if there is an alternative. thanks!

is a single 4"ID x 5.5"L port enough for an SSD 15 in 3.5cu ft. the box will be tuned to 33. trying to finish up the details on my enclosure and i keep questioning this.

hey guys im deciding on what to get in my setup but i was wondering about the Audioque AQ2200D i was thinking of running two of these with 2 FI BL 15s. on the audioque site it says if your not careful you might burn a coil or fold a cone ... i know the FI subs are tough but how do you think they will go. Thanks

Hello, I plan to build a box for my Q18's (bp option). The box will be 12ft^3 tuned to 28hz w/4 4" aero ports eash measuring 11.5" long. Each 18 will be receiving 1600w. Please tell me if my specs are ok or not. Thank you, Larry

hi there i need some help with a box design. i plan on sealling off the trunk in my civic. i have a fully loaded btl. the box in it pounds now on highs. its a dual ported box not sure if its effecting more or less out put of the sub or not just wondering if a single ported box will be different its tuned at 35hz. i have a little over 5 cubes. i am looking for a single ported design with both the sub and the port firing forward. i plan on also doing competitions with this setup. i just got a new alternator coming and 1/0 guage wire. i am going to get a kinetics 16 volt battery or two depending on if i need it. but what box design would you recommend for spl and bass race.l…

Hello all. I am currently running my 10" Fi ssd woofer in custom built ported box (sub up/port back). I love it! I have a kid on the way and would like to switch to a smaller sealed box for more space. I have a couple of questions: 1. Can purchase a prefab box that meets the recommened specs? 2. What size would be optimal? .6-1 cubic feet is what is recommended but would it be better to stay on the .6 side or the 1 cubic foot side? Thank you in advance...

Good morning to all. Ok, have a build question for the forum. I'm looking to get an 18" BTL soon and was curious as to what would sound the best in regards to sub direction. Room is not an issue as I have an SUV. I'd like to take a poll and get opinions on why you chose the following: 1.Sub up to roof and port to back of vehicle 2.Sub forward to driver and port to back of vehicle 3.Sub to back of vehicle and port to back of vehicle 4.Sub forward to driver and port forward to driver 5.Sub up to roof and port up to roof I'm really looking for ground punding and earthquaking when I want the sub to perform, yet sound decent with pop music as well. I have a broad range of mus…

So my parents are not goin to let me put my new fi btl 18 fully loaded in the cab of my truck. i want to know if run the port into the cab if it will have close to the same output. It is a 7.97 ft3 box at 30 hz. I know it wont b as loud but how much will it effect it.

I have a 15" fi. I got it used. Idk if it's a bl or q. How do I tell?

So, i hate to be one of those bums that asks for help on designing a box. (help?? who am i kidding, i need full assistance) I have a Fi BTL 18 just sitting here teasing me while i earn my money for a refurbished SAZ 3000d. i thought as i was waiting, i might as well build the box. Space should not be an issue, i want this box to built for performance. It will be used for daily use. So my question is, what would you do? From my understandings, tuning at 32hz seems to be the mostly desired tuning frequency. Alternator and batteries are all taken care of, just down to the box. SO! if space was not an issue (cause its not! =] ), what would your box design be for a Fi BTL 18 w…

Hello all. my enclosure will be finished soon.. like i haven't a lot of space in my CLK trunk,i have made a 3.6 cu ft @ 33hz box(after port and diplacement... 55 square for the port area).
