Fi Technical

I used to get Chris @fishercustoms to do my box designs but their forum is not active much and Im not sure if he still does them. Who else does designs, need for 2 FI BL 18's in a wall in a 2012 scion xb

I have a 2003 Chevrolet Tahoe and I am going to put a Fi BL 18" in it. It will be powered with a Rockford Fosgate T10001bd amp and a Kinetik battery. Just ordered it yesterday I have a general idea of the specs on my box in order to fit the 5-10 cubic feet. It will be about 9 cubes by the time everything is displaced. The only problem since I am new to car audio and this is my first system is what are the dimensions of the port? The box will be W 45" x H 20" x D 20" with 3/4" MDF. I want to tune the box to 32Hz. Any help will be appreciated. -Kasey

Just trying to see if I can get this sub re-coned again because I cant order the re-cone from the site since its a 12 with the 4 inch coil. Hopefully someone from FI responds.

I Have 2 12 Inch Fi BL's and i dont know what amp i should go with i was leaning towards a sundown audio 2000D but also was looking at soundstream PCX 2000D .. any suggestions on what i should do ?

Im considering eithet a 15" or an 18" Fi BL. I have an alpine mrd-m1005 amplifier (approx. 1100 watts rms @ 2 ohms). I want to stick this thing in a ported enclosure in the trunk of my cutlass, facing backwards. What would be the absolutely optimal enclosure size for these applications (both sub sizes)?

How big of box should i use for 2 15'' Bl's? (Space is NOT a limiting factor). Also i want to use 6 inch round ports tuned to 30-35 hz. how many would i need?

ive got a plan for my two 12" BL's. it comes out to be 5.5 cubes..is this too big? i can easly shrink it down or make it bigger if needed. thanks.

Hey everybody I have a Fi Bl D2 and i want it to play off a 1 ohm load off a RF P1000-1BD. I have and idea on how to do it but i need to be sure...

I want to get a BL to add to my collection, but I want a Dual 4. What's the extra cost from FI to do this? Thanx in advance. P.S. Only other options I would be choosing would be: P chamfer and Cooling.

I will soon be purchasing the Fi BL and was wondering if I will have to upgrade my electrical. The amp I will be using is either a sundown 1200d or audioque 1200d. Thanks

whats up i was wondering if someone could tell me if a 5.573 CF. after port and sub displacement enclosure with a port thats 12.5"s tall 5"s wide 20"s long tuned at 34.73 hz. sub up port back would be a good box for a 18" fi bl or would i be better off going with a 15" bl let me know thanks.

Hello everyone It has been awhile since ive las longed on to this accound but now im back. I got a Fi Bl 15" about 3 yrs ago and i would have to say it was the best/ loudest/best built sub ive ever come across. I had my box made by a guy out in Canada. His company name was Pound That Sound. Since i havent been on this website in awhile ive noticed that he no longs makes enclousres.... Ive been looking around for someone to help me with my next built since ive gotten a new car. Im sticking with the BL and i going to have the same set up likelast time, 1 BL 15" w/ hyper pole option. Now my question to anyone who wants to answer is... is there anybody you would recommend for…

So I'm new to car stereo and was hoping yall could help me out. I've been doing alot of research on subs and have decided on a 15" BL for my tahoe. Im wondering if yall could help me make some decisions on which options to chose for the sub itself and what kind of amp i would need to power it. I'm looking for some pretty hard hitting bass at some points, and at others i just like some good sounds. Thank yall for looking and for your opinion.

Well i decided to see if my 15" Fi BL is working before i get my box so i installed it without the box... I wired it parallel and when i turned my car on to play some music I would say about 1 min smoke started to come out ... it wasnt very much smoke but i need to know if this is normal for a new sub to do that.. also the sub was getting hot... what could be the probelm??? :

What can i do to stop the screws from coming out the box holding the sub in

I have a bl 18 with a jl 1000/1 running it..the other day i was driving and it jus shut off, I checked to see if i could see what was causing it and the amp was still on but the sub wasn't working..a little bit later it came on and would shut off after it hit a couple times. Then it came on one day and worked flawlessly for 3 or 4 days and now its shutting off again. I think it might have something to do with the temperature because the days it worked it was 50-60 out instead of in the 40's on the days it shut off. I checked the ground and all the connections and they're fine. what do you guys think it could be? please help me out thanks

I have two fi bl tens and I can't figure out which recone to get? What is the difference between the 2008 and 2009 model?

In order to get a 1 ohm load out of the 2OHM DVC, I wire the two negative terminals together with speaker wire coming out of one of them, and both the positive terminals with speaker wire coming out of the same set that the negative came out of right?

Ok. i am planning on getting 2 15'' Bl's. (Dual 1 ohm, cooling, and flatwind). How much power can i feed them without buring them up?

I have the following system... '96 Jeep Grand Cherokee 2 18" Fi BLs 2 Rockford Fosgate T10001's 1 Rockford Fosgate p500-2 1 Pair Infinity Kappa Perfect 6.5" components 1 Pair Alpine Type R Coaxial 6.5" Lots of Lightning Audio Wire Alpine CDA-7897 Head Unit + 6 Disk Changer 225 amp Excessive Amperage alternator Box tuned to about 34 hz My question is, I cannot for the life of me get my subs to play the same. They are phase, wired with 8 gauge, and the polarity is correct (as long as the subs are labeled correctly). I have the amps set for master/slave, set to give each sub 1400 watts. Does anyone know what could be causing this problem?

i want to recone my 18 to a 10, any body know who i can contact for one or a price?

I am interested in purchasing the BL 15 and I have a few questions. It says that the RMS for this model is 1000 watts. I noticed that steve meade has 4000 watts RMS to his BTL's. Does that mean that the BL series can take 2000 watts RMS and still function as a daily driver. How is this possible for steve meade when the speakers are rated at 2000 watts RMS or does he own an upgraded version?

Hey everybody, as you can see im a newbie lol but my question is im plan on getting a 15" Fi Bl w/ p chamber option and its going to be running off a Rockford Fosgate P1000 1bd (1000+rms) and i was wondering if I needed a new car battery or should i just hook up a cap to the amp

I'm in need of some help on a box build. I'm planning on getting 1(one) fully loaded FI BL 12" dual 2ohm. I would like to know what size and type of port to use, I would like a slot port (not sure what its called) tuned at the recommended 32 hz. If some one could get me some ideas on the size of port to use and that sort of stuff(i have no clue how to make a good port). I have a 3d cad package (SolidWorks 2007) to were I can design it my self I just have no clue what size and type of port to use, or how to use it. The set up is going in a Chevy Cavalier 2 door (rear seat does fold down, not sure if its relivent) and the amp I'm using is a Power Acoustik BAMF 2000/D (r…
