Fi Technical

I bought my SP415 dual 2 ohm back in October and received it in November and after only 5 months of use, the foam surround is ripped. I can't seem to figure out how this could have happened so any input would be great. Also curious if this is covered by FI's warranty. But here's the setup: -1999 Grand Prix GT Sedan -FI SP415 dual 2 ohm wired to 1 ohm. No spaced spider and no cooling (daily use, didn't see the need) -AQ2200d tuned to 2100 watts RMS using a multimeter -DIYMA oversized 0awg CCA power (appx. 22') and ground (3') with a 200 amp circuit breaker near the battery -Optima Yellow Top -Ohio Generators HO Alt (its an older model but I had them test it and it puts o…

So I am trying to decide on which Fi.Q I want... Either the 10 or the 12. My plan is to build a custom sealed enclosure to sit in between the second row captains chairs in my Tahoe, and the sub will down fire. I am leaning more toward the 10 because of space constraints... the maximum size enclosure I can fit in there is 27" L X 14" W X 10" H... So would y'all recommend the 10 or 12 with that, and what cubic footage for the enclosure? Also, What amps would pair well with the Fi? I listen to some rap, but mainly mashups, EDM, and lots of rock/country (basically everything hahaha) Side question... I don't know if any of y'all have a Tahoe with the Bose upgraded sound…

Ok I have a 07 Saturn ion I'm going to put in a q18 in the trunk. The box from the cut sheet for a ported box won't fit.... My trunk is 14.7 cf so getting a 7 cf box in there can happen I'm just clueless on how to go about it. My opening is 19x40 Ball parking that. of course there is the angle too... Any tips or ticks to get this built and in there would be very helpful. Also I hope I posted this in the correct spot.. Also I feel havering the sub firing tends the trunk lid would be my best bet

I'm trying to order a bl 15 and everything goes smoothly until I hit pay now and it tells me there has been an error and to choose a different payment method. I have Discover card and have used it to purchase since I've tried purchasing from Fi and it works so I know it's not the card. I have E-mailed Fi twice since Saturday night and they still havent responded. I would like to order as soon as possible. I've seen on here that they are behind on orders right now or something, but it would be nice if they could reply to me. Maybe they'll see it on here and help me. Am I missing something that I need to order my sub? Any comments would help. Thanks

I own a BL and am buying an SP4. will this box design work perfectly for the SP4 and well enough for the BL? did i screw up on anything? at the bottom of my port i have bracing crossing it, will this be an issue? should the port be fully open down to the bottom of the box? i could not find any great info on port area for the SP4 so im sitting a bit over the 16 multiplier right now. i was thinking of adding a bit of that fluff to the box to make the sub feel it was in an enclosure closer to 8 cubic; is this a good idea? im going for SQ at high volume, or at least as much SQ as the SP4 can give me. what should i change, all opinions welcome. thank you. http://imgur.…

I own a 18" BL fully loaded on a kicker ZX1500.1. this has done me well as a DD setup for a year but now i want more. I am looking for more low end and more volume with out sacrificing much of my high end. my box is currently tuned at 44hz @ 5.4 cubic feet and i was planing to build a new box tuned to 35hz @ 7.99 cubic feet. i have the option to swap my 1500.1 with a 2500.1 plus a couple hundred and stick that behind the BL. would i blow it with this setup assuming im not an idiot with gains and the bass blow knob? my second thought was to sell my sub and box to buy a SP4 and stick that on a BC3500.1D crachendo amp. i read that this amp can run .5 stable where as my kic…

just ordered my bl's and sketching up a box, could i get a little advice if this box will do

Got a 12" Fi BL that needs reconed but was curious if I can recone with a totally different brand ie. Incriminator, Ascendant, Sundown, DD, etc

Driving along one day and my 12" SSD cuts out. Its in a sealed 1.1 cu ft box. I l=pulled the sub out of the box, and noticed that an internal lead on each of the voice coils has come undone and is frayed. (Photo: http://www.i.imgur.com/jCFOwGQ.jpg) I called the shop i got it installed at, and they said they don't touch sub repairs. Is this something that can be repaired? Am i Going to have to send it in to Fi to get reconed? Does anyone know a good shop in the SF Bay Area that could fix this? Also, after a bit more research, it seems this can happen when using an improper sized box. But i was using the Fi recommended 1.1 cu ft for a sealed box. But I do not have the…

I got a 93 740il, i want to mount the subs on the rear deck and do a blow threw... dimensions of the trunk are - width 3', height 1.5', and there is a difference of 6.5" from top depth to bottom depth being the top is less, the port thru the rear seat can be a max height of 1.5' and is set at 1.1' without cutting any leather seat and width of 10", i have allot of room to play with the depth in the trunk well over 3' in the least deep spot, i tried using re's box calculator but it didn't help that much. thanks.

does anyone have a blueprint that I can use for a single FI Q 10'' tuned between 28-30hz?

So I got 3 15 in dual 2s wired in series tuned to 33hz on an audiopipe 30001d amp isn't turned up a little under half no clipping and as normal subs gets a little warm never hot enough to where u can smell the coils burning up. Now my issue i ran into today Is I was listening to them going to lunch with no problems and shut the truck off and came back out and just turned system on and how I can describe it is one of the subs instantly started to make a distorted rattling noise... kinda sounds like the sub is farting all lower frequency but not noticeable at higher frequencys. I pulled speaker out and the coils dont have any noticeable scratching or rubbing.. Now I'm just …

I want to build a box for an fi ssd 10. Should I go ported or sealed. I'm leaning towards ported. I could use some box design help and any suggestions. I'm waiting on my brz 2100 to show up until I order the sub but wana get going on box designs

I have a 12in fi bl fully loaded and a sundown saz1500d with all 0g wire and stock electrical. My alternator is 110a. Im not sure what I will need to do to see full power from the amp. Would the kinectic 950 be enough for an extra battery in the back?

hey guys i posted a few months ago about half of my port being covered up and basically it isnt much louder and it makes the music sound sloppy so i dont use it i was wondering if anyone could give me tips on a new box that i could build for it to get some more out of the sub box specs: 35" Wide 16 3/4" Deep 27" Long port specs: 25" Long 5 1/4" Wide 16" deep (outwards) 11 3/4" deep (inwards) (port isnt typical L shape) http://s1284.beta.photobucket.com/user/FiAudioUser/media/boxspecs.png.html?sort=3&o=1 (pictures) i drive a station wagon and have a few more inches long/wide to expand if that gives me some more DBs any help guys? ask any questions you…

Is there any recommended size fastners to use on the N3? From what i saw the holes were only about 1/8".

Just lookin for some input on an amp that will power a fully loaded 12in fi bl at 1 ohm. My sub will be here this week so i want to order my amp soon. Any input will help. Please state the amp/amps you reccomend and why.

Would any one happen to know the diameter for the BL 15.

i have a kicker zx1000.1....1000wts rms at 2 ohm planning on getiing a dual 1 ohm 10 inch or 12 inch bl for an 2001 eclipse need the recomended specs for the 10in bl and 12 inch bl.. which sub would be better for my setup and car?

Hello, This is my first time building a box. I would like to hear any thoughts you might have before I get to building. I just recently purchased 2x FI Q 12's dual 1's with cooling, and spider. I designed a box for a 2002 gmc envoy. These subs will be pushed by a Crescendo BC2000D. (May eventually upgrade to a 3500 or 2x 2000's). Box is 5.0 cu ft and is tuned around 32hz. Heres what I came up with. My main concern is if I did the port length correctly and if I calculated the bracing displacement correctly.

Already have a ported box for the sis as I built it last week with the purchase of these subs in mind, but just read the pinned thread about the Qs. I listen to everything from avenged sevenfold to maroon 5 to jack Johnson to lil Wayne and kirko bangz. So I really am Looking for a setup that "does it all" and sounds good while doing it. A lot of music other than rap spuds muddy and sloppy on my current RE SeX 12s (prefab and custom enclosures) and just haven't been happy with the sound. Everything kind of runs together. With that being said, how will I like these subs? Current box is at 33 hz with approx 1.9 cubes per sub in the trunk; subs up, port facing forward on the …

Was wondering if those cut sheets are still optimum to today's Fi Q12?? I'm purchasing one at the end of this month and would like to build the box while I wait for delivery. Going for a ported enclosure but for fun was gonna build a sealed too and check them both out. Thinking of getting the sub fully loaded with every feature just cause I can and run it on a Q1-1200D from Soundqubed at 1ohm producing 1200watts. It will be in a 2005 jimmy 2 door so room is not a factor. I listen to all types of music and would love clear crisp bass but also able to bump it when I feel like it. I know there is no magic box that gives me both SQ and SPL just want good sounds on musical mu…

Hello all, need some input from the pros. Currently have my Q in a box from obcon (1.25 cuft before displacement) that a friend gave me. The enclosure is made of paperish mdf that basically turns to dust so its time I get a proper box. Now my question is, should i make it for the max 1.5cuft after displacement? Want to keep the notes tight. Also I have it powered with a rockford t1000-1bdcp (birth 1366 @ 2ohms). Thanks in advance for the help.

I'm really considering using Fi subs for a new comp setup. Vehicle is a full size pickup, so it will be a blow through solution. The primary question is, which sub(s) to go with. Goals: 150db at headrest, 130db outside on music. It will be entered in MECA's spl and park and pound format. P&P being the 130db outside goal. The two goals are the max points I can attain for what I'm looking for. Obviously if it is higher that's fine. One individual at the 2012 finals did a 155/129 on 4 speakers in a wall (don't know brand and I think they were 15's). I was originally thinking of a single 18, but I'm not sure that will get there. Also, if possible, I'd like to keep the b…
