Fi Technical

I broke my terminal loose pulling the sub out of its box, I tried crazy gluing it back but that aint working, My question is, whats the bolt for on the terminal, the terminal is not screwed on, it looks as if it was just glued on over top of the screw instead of screwed down. Now, I cant get the terminal flush with the screw head to even glue it down properly, what would you guys suggest? Right now, the terminal is just flopping around, I know that cant be good

whats the most power you could safely put through a btl 18 loaded, and not blow the coil? im just wondering what some have tried and found to work where as someone might have tried ____ and blown said sub.

hey there guys i am looking for a box design. i need it between 4.5 and 5 cubes. either sub in center or on side. i want it to have interchangeable ports with tuning at 32, 38, 44 if its possible. i have money if anyone of you guys on here can design me a box for my 15" btl that would be great. i will get my max measurements up later today.

I am planning to purchase a BTL 15 when they are available, i would like to know what kinda applications this sub is gonna be adaptable to. I had a DD 9515G, but everytime i talk to them via e-mail or on the phone their customer service is severely lacking lately. So i sold it. I would like to run one of the BTL's in the DD's place daily in a T-line Enclosure, and then in a standard slot ported, or possibly kerf ported enclosure for when i wanna meter it. What kind of options are gonna be available, and what the specifics of them. I went the the website, and the options and just complete overview of the sub is obviously being revised for the new model. Options i reme…

I recently purchased one SSD in my old box and i absolutely love it. I will be ordering a second sub in a month and need to build a box for it. I am trying to figure out the dimensions for 2 12's around 4 cubes tuned to 32 hz. I am not sure how to create a box that fits these specs. My dad and i built a box for a w6 but all the dimensions were given so it was very simple. Any past build specs would be very appreciated.

About to get started on getting a box for a fi bl 15. I have the space so was thinking about 4-5 cubes as one fi page suggests 2.8-4 and another 2.8-5? want to hit lows and still have it get a little loud and don't really know 100 percent about tuning but was thinking 33 hz ? Any suggestions I appreciate or input...power is a saz 1500d v3...thanks for your time

I got the box built a few days ago.. just wondering if I could throw the dimensions out here and you guys can tell me what it is size wise. He told me its around 8.7cubic feet and i think he said 32 hz is what its tuned too.. damn thing is huge, but here is the measurements 48 1/4th across, 20 1/8 height on the face plate, 24 1/2 tall.. the port i wasnt 100% sure how to measure properly so ill tell you what i did and if im wrong correct me and ill run out in the garage and re measure. I basically stuck the tape measure in the port, hooked on to where the inner port board stops and took that as my port depth measurement, which was 17", port is 6 7/8 wide, 18 1/2 tall, its …

I'm thinking of buying a FI Q to put in a sealed box in my spare tire well. The dimensions I have to work with are 24"(width)x26"(Depth)x10"(height). I'm a complete noob when it comes to building boxes but want to try to do this one. How do I figure out if I can make a box that will work with the FI Q with those dimensions and what size to make it etc?

What is the lowest amount of watts to feed a 12" Fi Q and still get decent/good performance? I'm shopping for an amp and want to see what my options are.

I have a 12" BTL with pole chamfer and my Memphis MCD2500 amp is coming in soon. I want to get everything ready so when the amp arrives I can install it right away. This is my mustang 2004 stock electrical: 130-amp. heavy-duty alternator 540 CCA heavy-duty battery Battery amp hours (58Ah) Battery-rundown protection I will be doing the big 3 wire upgrade with 1/0 gauge wire from batt to alt to ground. Besides that, what else should I invest in? I'm trying to keep it as budget as possible. Thanks. PS> This is my daily driver.

Well right now im running one 15 Fi Q in the trunk of my civic. The box is around 3.2 after displacement and tunned around 33. I got it ran off a memphis 1000D. It sounds pretty good but i was thinking about doubling my power and getting another 15 Q. Problem is i barely have enough room for one in my trunk. My civic is not my daily driver and i was possibly thinking about walling it and running 2 15Q's off of 2000rms. I was just wondering everyones opinions on this? Would it be worth walling with that power and how do u think it would sound in a good built box. Any help or sugestions would be appreciated, figured i would get some opinions before deciding on this, thanks

I was wondering if I can run my friend's Fi Q in my box that is 4.5 cu ft tuned 32? It has BP option, and I would be running about 1000 watts to it. Would the sub be fine as long as I am responsible?

I'm just curious as to why the Universal option isn't on the subs by default? It doesn't cost any extra money, yet i do not see any disadvantages of having it done to a sub even if you do not want it. So... is there any disadvantage of having it even if someone doesn't want it?

just got a blow sx 12 and the glue on the top plate gave way when i pulled the coil out, so the gap collapsed, is there anyways to realign it, if so how much. 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?

I have 2 mtx thunder 7801d amps and was wondering if that is enough power for 1 of the Bl 18's? If yes what options should I choose for the Sub? I know I'm going to need the daily option for sure, but after that I'm lost.

I need box plans for a Fi Q12 (dual 2). It going to be powered by a Sundown 1000D. I want it to get loud but also have SQ. So Im thinking tuning it to 32hz. Fi recommends 12-16 square inches of vent area per cubic foot of volume. The demensions I want to use are 14.5 H, 28 W, 18 D. (can change alittle)

ok so what im gunna do is put a single 12" BL into my f150....i have a bench seat in the rear so im gunna fold the short side, which is behind the passenger, and put the sub box there....i have approximately, 18" wide 16" deep and about 20" in height...the height is flexible tho....i have a kicker zx1500.1....can any one please help me design a box? thank you

Ok I'm planning to run a 15" BL in my trunk and was wondering what box idea would be louder. 1. A regular ported box facing the rear. 2. Wall off the trunk and have the sub facing the cabin in a ported box, with this setup i could make the install look nice with the box i would do the plexiglass with mirror inside of it with some L.E.D. lights in it or something to see when you pop open the trunk with the amps on the floor with a false floor, itd look real nice but it gotta sound good too...would that way be louder??? and my seat fold down if that has any factor...thanks

I want to build a SPL enclosure for a show coming up and wasnt quite sure about size and port. What I was going to build was... 42" x 15" x 10" with a port that was 10" x 4" x 21" Will this be good ?

So I got a 12" Q last week and I LOVE it but my sub cuts out or has alot of background noise and i hooked it directly up to the amp and it plays fine and I am figuring that its the speaker terminal because when i put my finger on the negative it starts to play but when I take my finger off it stops? and In addition the - wire looks charred on the inside connecting to the terminal so my main question is has anyone else had this problem and what would be a good solution?
