Fi Technical

I am getting one 10" Fi SSD sub-woofer very soon and I am having a bit of trouble on what to do for the enclosure. I drive a small, 1998 Ford Pickup, single cab. I am convinced, and determined, that it is possible to put a sub in any vehicle, but there really is very limited space back there to put anything. Does anyone have any experience or suggestions? I am looking for the best sound I can get, but I understand if it won't be optimal. Getting the materials and building it will be no problem, just need to know how to tackle this.

were can i find a ufo style btl at ive been lookin for a long time now

Hey I have a 12" fi bl and I need to recone it I have it all striped down and the basket I sanded all that crap off but I need some advice on how to recone the sub and what I should do thanks for your help

Hi, Need experienced help, I just received and installed my Fi SP4 15 D2, powered by a Crescendo B3500D(the volume on the amp is up to 75% on the gain knob on the amp and bass boost in 0 and on the head unit the subwoofer level is in max), and I feel the bass is weak for what I expected... 1- Is this normal? Or what should I do? 2- Is there a specific way to put the ohm load down to 1 ohm on the sub? 3- What specific grill fits this sub? Thank you.

got my sub couple of days ago and need a design. its going into a 99 cadillac escalade so theres plenty of room... can you guys help?? listen mostly to heavy rock and some rap.

Hello Im building a box soon for a Fi BTL N2 15, and its going in a honda accord. But im tired of thinking that all the sound is in the trunk, so i was planning on removing the backseats, and build the box so the sub and the port would point forwards. (So the sub and port would be right behind where the seatback's should have been and the box inside the trunk. (kinda like this: What do you guys think? Would i get more sound pressure in the front seats this way? Or would it be better with the sub in the trunk and maybe port up the parcel shelf? Any ideas what would give me most pressure in the frontseats? Thanks alot

i know first thing everyone will say is why sealed, ive just been a sealed type of guy all my life, nothing against ported..but its not my taste..so i know on fi's site for 18's they suggest 4-8cu ft per sub..im having a shop make my box for me so its not like i can experiment with different sizes..so for a sealed application and for a mix of rap and rock what do you guys suggest in a box size for each 18? space isnt a issue its going in the back of a denali

So as of right now i have a Q 15 powered by a BXI 1606 running at 1 ohm so the sub is dual 2. My next goal is to get another Q 15, but I really want to get a RF T3000 but they would have to run at 2 ohm and be dual 1's right? So i would have to recone my current one or 2 (if everything goes right) to run at 2 ohms. But then agan if i end up w/ 2 dual 2 Q's i could just get 2 RF T1000's I just need some advice -send in my current Q for a swap and get both dual 1 so i could run the T3000 -keep my current Q a dual 2 and run each off T1000's How much actual power do the T1000's put out? Do these hold up to the other T line? I know a T3000 would be very generous for 2 Q's but…

So my q12 arrived on Wednesday to my work (where I have all shipments sent) but I was out sick for two days and I come into work this morning to find the box with a big hole in one side and looking very rough. https://plus.google.com/photos/116140861359253571917/albums/5871144803493812177 The magnet has damage all the way around the bottom edge, cracks and pieces chipped off. I have not attempted to hook it up yet and my question is should I even bother...

I have a 98 reg cab s10, i want to do either 2 10'' Fi SSD subs. I would like to know how many i could do and rather do it sealed or ported. Any help would be nice thinks

I need dimensions for bl 15 ported box?? I have a hifonics bxi 2008d amp to go with it. and this setup is in a 2001 dodge ram 1500 sport, so the box needs to be on my back seat. any help will be appreciated. thanks.

hey guys, im gettin either 1 or 2 amps, here are my options, 1 of these bridged http://www.sonicelectronix.com/item_12212_...+BXi+2608D.html or 2 of these http://www.sonicelectronix.com/item_12210_...+BXi+1208D.html these are mono d class amps, now the bridging of the single amp is my concern, i ordered dual 1 of the BLs, would this diagram work? the subs are 1 ohm correct? so would this diagram still be somewhat valid? and if this does work, how would i design the box, because currently im planning to separate the chambers, unless one of you can direct me in the right way or i can jsut get the 2 smaller amps

I'm getting absolutly no sound out of my sub it was working fine for about 10 minutes earlier and than i unhooked it so I could set the gain correctly with a dmm and after I hooked it back up I got nothing from the sub The first time I hooked it up at had it at 1/4 gain up so I'm sure it was not clipping and I only played it on low volumes, I also didnt smell any burning So could could sub be blown? Dvc 2 ohm wires parallel to 1 ohm off kx1200

Does anyone know where I can buy these plans or get them for free I can't find any.

I was wondering if anyone would have any insight on my possible set up plans with my enclosure and sub and amp. First off my vehicle is a 1995 3000gt. I want to go with a single sub because it will be easier and far cheaper to set up. So would a 15 fit or would only a 12 fit? I was thinking either one of those BLs with all the options on a decent 1000-1500 watt amp would probably be ideal? Also are the speaker wire kits on ebay that are 2 gauge ideal? They cost like $40-$70 on there. If anyone has any suggestions or recommendations, I would greatly appreciate it.

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 …

n00b to the forum that is , did this one for a local guy. I'll let the pictures do the talking. It was a little dirty sorry, I had to snap pictures off quick and vaccumed when the guy picked it up. Comments welcome, I've got a few other BTL enclosures I've done I'll toss them up as well otherwise check out my photobucket page HERE

Is it safe to run a single fully loaded 18'' BL on a Rockford T2000 @ 1ohm?

I am running an AQ-1200D @ .7 ohms to a 15 BL and my friend installed it yesterday and set the gain on the amp a little less than half way and when i turn the bass knob about 3/4 up and turn the volume up to like 25 out of 35 the clipping indicator on the bass knob illuminates on and off with the bass hits on some notes. its aggravating the shit out of me because I just spent alot of money and I dont want my shit to fuck up. He told me the amp could be too small for the sub or the HU is sending out bad waves to the amp. It sounds amazing, dont get me wrong. I just wanted some advice on how to get the clipping to stop. I have a Kenwood Excelon KDC-X792 head unit and it has…

you've got mail

I have 4 FI BL 12's and was wondering how many cubes net should I build an enclosure for them? Also how low should I tune to do hair tricks? They will be seeing a little over 6,000 watts of power.

I've posted one thread similar to this one once before, But I felt the need to make one a little more clear. I own a Pontiac Grand Am. One of the worst vehicles to work with when it comes to car audio installs due to very limited room. I got an idea the other day sitting in the front seat looking back at my folded down back seats. I figured.. what if I took the open area where my seats fold down leading to my trunk area, put up one peice of 3/4 or so MDF across that opening, cutting a opening in it for the 18" BTL and another for a port that's tuned to 30-35 hz and using my entire trunk area as the enclosure, without the need to build an enitre box. Since there is not eno…

I've been looking for T/S perams for the FI BTL 18. Searching to no avail I need some help. The reason I need the numbers is to plug them into Termpak so I can design an enclosure for a forum buddy. Any help would be very much appreciated. I need the following: fs (in hz) Qts Vas (in cu.ft.) Xmax (in inches) znom (depends on coil config. I am aware) Pe (rms watts) Spl (in db @ 1w/1m)

Well here it is. A freind got a new 18inch btl, and he was throughing out his 10. I figure, since I have some left over LN from a computer cool, I would design a box and have LN cooling the sub. Yes this will involve some major work on modifying the sub. This ever been done ?, I just want to run 8000rms to it. And not have er burn. This is my first post aswell, and ill be ordering some subs later on . I figure if I vaporize the LN and have blowing through the sub, that it atleast not kill it for 10 seconds of playing. Crazy or worth a experiment ?

Alright, I have a MTX Thunder 2150 and MTX 7000 12 in sealed pre-fab as a temporary setup in my 08 extended cab Sierra. Signal is off stock Bose HU rear driver speaker on a LOC. Needless to say I want a bit more oomph along w/ a my passenger seat back. Also, I believe I'm getting a full signal there but if someone knows otherwise please let me know. So I am willing to give up my rear center seat space, and am looking to do a small box behind the center console rather than downfiring under a seat. I am thinking a FI SSD 10 combined w/ a used MMATS, or possibly a new American Bass amp around 1000 to 1250 rms (and yes, I'll consider a used Sundown). Want to keep it US made b…
