General Fi

Hi, im about to order a fi btl in the next few weeks. Im deciding between a btl 15 and a btl 18. I have a hyundai elantra with a 220 amp alternator, 2 batteries and a soundstream rubicon 2500d. I listen to almost all rap and im looking for the loudest system i can build for the lows. I can only fit a 6.7 cube internal volume ported box which is 5 cubes net. I dont know which sub would be louder in this size box. But i really want the 18.

I have an 89 Mercury Tracer, I have 7.7 cubic ft (internal volume) {39 in W, 23 in H, 18 in D} I would like the box to be tuned to about 32 HZ. I will be running about 3500 watts to the sub. any help would be appreciated, I do not know that much about tuning an enclosure.

The cosmetics aren't quite done yet but I got the sub running and with what little (in comparison) power it's getting from that old Opti 50C off stock electrical I'm more than happy with it. Once upgrades are done and the 3000d is here, it will REALLY bang! The board isn't allowing me to put up a video due to some stupid code thing, so find it at "maximusde34" on youtube. youtube video at "maximusde34" not sure how to put videos on here!

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 am looking for demtions for an fi btl subwoofer box i have a 1995 chevy blazer and the room i have to use is 22 inches high 25 inches deep and 38 inches wide the recomendation is 5-10cuft so could anyone tell me what dimentions to make my box and how big the port should be

how much power can you put to a btl 18 for bass race???

I was thinking about getting a btl 18 and i was wondering what options i should get on it thanks. and by the way i listen to rap alot and i want it to be mostly loud. Thank you

hi everyone. I would like to make a purchase for BTL 18" 4000 Watt X 2. So i want your advice which is the most suitable amplifier and mono amplifier to support it. Need help..

being that the BTL is more spl oriented<<--- or does it matter if a sub is spl oriented? how does it handle the lows?

hello i have a quick question, ive seen the btl 15 has a xmax of 16 mm and the bl 15 is 21 mm so the bl shoud come out more than the btl how can the btl be louder then?? right now i have a bl15 fully loaded, whats the most power i can throw to it. i was thinking of a rockford fosgate t10001b is this a good amp or is there something close or same cheaper?

Wondering when you guys expect the BTL backorder to be filled and shipped? Maybe its already done I don't know ha just seeing what the overheads looking like. Thanks

To those who are currently on the BTL back order you will be receiving a call tomorrow (Yes, Saturday) in regards to the current back order status. You will be receiving a phone call somewhere between 9 and 5 pacific standard time tomorrow. I'm sending an email out now to those who have emailed in regards to this matter. Thanks! Nick

Well my birthday came and I was pumped to be getting all my goodies. My girlfriend was sad as she had ordered something for me, only for it not to arrive in time. Well today package 1 of 2 arrived. A sweet 15" BTL loaded. I took some pics. All the pics taken either mine or otherwise really dont give these subs credit. MASSIVE!!

hi i was wondering can u order another box for the btl 15 THANKS ]

nevermind. i found it.

how long does it take for the btl to break in? ive heard the subwoofer break in is a myth

I got my BTL 18 yesterday!! Funny thing is, I never got a tracking number.. As a matter of fact, I checked the invoice page on Fi's website yesterday morning and it still said "Your order is being processed." It still says that now that I've got it haha. Pictures coming up later today! If I wasn't at school I'd put em up right now. So to all people waiting for their Fi sub, don't be too discouraged. It could be at your doorstep when you get home today!

What are the ID, OD, and WW of the old 2 stack, old 3 stack, and the single slug BTL coils? Both the D1 and D2 of each.

is 11 cub. ft enough to run 2 18" btls with a port?

i have a dodge magnum. i see alot of people building boxes that have the subs firing up and the port towards the rear. ive never heard a car/truck with the box like that. ive always used rear face rear firing boxes. is there a difference? is it noticable if so?

I am looking for some votes to try and win this contest so I can get a few bigger amps for my BTL's. Please vote for me Justin Wilson #38 at http://www.rockfordfosgate.com/promotions/2010_WhatsYourVolume2.asp#vote Thanks for your time, Justin Wilson

as i had anticipated. Of course i still need to upgrade to the big 3, and running a bxi1606d at 1ohm. It's in my 99 Denali and i made the box to 7.5 cu ft tuned to 32 hz. I double bffled all the walls to a total of 1.5 inch thick. Do i need to upgrade to 0 gauge wiring? A bigger amp? I noticed that the BTL was SUPER stiff! Mayb i need to push 3000w to it instead 1600

I havent powered my subs up yet, nor have the been mounted. They've been sitting in the boxes they came in since I got them last year as a present from my gf. Not dropped or anything like that, its weird I've never seen anything like it. I pulled one out to show a buddy of mine the sheer size and outstanding build quality. While doing so, I noticed a crack in the magnet. Not a small crack either, it goes horizontally, all the way around the sub. And it wasnt there when I got them. I've emailed Scott, but I would like to see what you guys think. I'm a little concerned. And I was planning on inverting them, cause they have a very sexy ass. Here are a pictures of the crack: …
