General Fi

Well I placed my order on Dec. 4 and my order still has not shipped. I spoke with Shawn on Monday and was told it would ship out Tuesday or Wednesday it is Friday now and they are still not shipped. I have been very patient upto now. I was not quoted a time frame of this length at time of purchase. And I have been mislead on several occasions. I know they are busy but give me a date and stick to it. I wasn't expecting to wait two months for my subs that's not what I signed up for. Thanks, and any help having this issue resolved would be greatly appreciated!

So i got a FI BTL 12, AQ2200D amp, 0 guage kicker wire. Optima Red top under the hood & an extra " dumptruck battery" ( if you will) in the back. JVC KDR300 head unit. & I HAVE NOT done the big 3 yet. anyone got nay advice so i can get the full 2200 watts out of the amp without clipping the sub due to voltage drop?

Hi, I have a strange issue that seems to be getting worse. Ill start from when I think it happened. My friend and I built a 4CF box for 2 FI SSD tuned to 30HZ. When we put the box in my cobalt I noticed that the wire terminals were upside down. I didnt care at the time I was just wanted it done for the time being. This was back in 2010. A few weeks later I decided to have my other buddy help me remove the box and put it in the right way.and reposition the subwoofers so that the labels looked the right way. When I was reorienting the subs I unhooked one completly to show my buddy,turns out when I hooked it up I wired the coils out of phase. I didnt know until I was on my w…

The Fi BTL subs are amazing! I don't know if it is the new head-unit I have or the new amplifiers but WOW. It is amazing how tight the sound is compared to my old setup. My old equipment had a hard time keeping up with fast bass tone - changes and sounded a little mushy. I don't know if it is because I am running a higher ohm rating and therefore the subwoofers have a little more control, or if because I am pushing with 1 amplifier and pulling (180 switch) with the other, or if it is because my source unit is just THAT much better with the signal or what but - I am truly impressed with how good musically the subwoofers are. How clean and tight the sound is. Fast or …

Hi guys, I installed my 12" BTL N2 2 days ago. The box is ported to 32 Hz, 2.1 ft3. I run a Sundown saz 1500 at 1 ohm. Last night I took time to test this setup and I was surprised to hear a strange sound at the highest volume. I kept the exact same settings than with my previous setup (1 ssa xcon 15" on the same amp). On a certain note on a song from Mike Jones a weird sound is coming from the sub, and not in the port. On low bass notes there is no problem, but on a higher note the sub reacts badly : how can I describe it ? Like a sheet of paper moving ! It's scarry. I need to turn down the gain on the amplifier. I checked the inside of the box, nothing was loosed, …

I currently have two 1ohm stable amps, soon to have my two dual 1ohm subs, I wanna strap my amps to have a final 1ohm load per amp, I understand that that when strapping final load is split in half, so when I wire it, would I wire each sub individually series/parallel so each sub is 2ohm? Just wanna make sure I got this right first time strapping So basically Step 1= series/parallel Step 2= + of each sub to + on master Step 3= - of each sub to + on slave Final ohm per amp 1ohm.........I think??

Here is the system: Basic Kenwood deck (for now) feeding a US AMPS 6000. US AMPS 6000 feeding one BTL 15. For now, two runs of 0 gauge running back off a 250-300 amp alt feeding three Stinger 1700s. We want to do street beat under USACI rules which is pound the crap out of it for 30 seconds. The amp will not be ran at full tilt just so you guys know. I was wondering what kinda box you guys might recommend and should we get the fully loaded BTL or are there a few things we don't need. This will make for one of two FI systems being built this season and I will keep you all updated as the builds progress. If your interested the other is four FI BL 15s running off fou…

I have 2 18 inch ssds dual 1 ohm with 2000 watts series parelell with the hifonics 2006d and when i turn it up i get a real strong glue smell. My gain is only just past half with the bass boost at 10 O' clock and i tried a couple different 1 ohm wiring diagrams, is it the smell of the box or are my coils burning?

I'm looking to buy some speakers but i'm a little stuck i'm looking at either one 15 BTL or 2 15 BL's. The thing is i really want to know which would be louder as far as bass and quality? What kind of setup should I use? I'm about to buy me a 2000- 2005 impala ls 3.8 v6 125amp alt. With the two Bls would i need to get a h.o. alt or would i be ok with just 1 optima yellow top in the trunk and a battery under the hood, of course the big 3 is going to be done but will 4 gauge wire be enough. also this is a daily system that i'm setting up I'm going to get 1 1500 watt brutus mono amp for now. a little help from everyone will be great thanks.

So, I get the general jist of an IB setup. Deaden the entire trunk, make a baffle to hold the sub(s) that completely seals the trunk from the rest of the car. Here is my question though, what do i do with the rear deck. I hear of people doing a lot of things regarding it, but I really have no clue what to do, if anything. Help would be great as this is my very first IB setup. I am sure more questions will come about front stage, but later. Or do you think 2 15" Q's sealed would sound better. I have only ever had ported and am ready for a postive change while making room in my trunk, tired of having no room. Thank YOu

Ok, i will probably be running 2 bls off of a sundown 3k. Not sure if i wanna do 2 15's and keep them straight upright firing through my blowthrough or have 2 18's slightly angled firing through it. What i am curious about, is there really an audible difference between the size of these two woofers if they are running the same power. I know the 18's will probably score higher in comps, but i doubt i will ever compete, so no point in getting less than a db more and losing that much more of the bed of my truck.

I was wondering what does the "FI" in FI audio stand for? Thanks for any answers.

Ok I'm sure some will get a kick out of this, but this is my first time with an Fi sub. I have everything wired up and just have to screw the sub into the box, but I'm not sure how to go about doing that. It looks like the whole surround is metal with rubber on top. There are some partial holes on the bottom of the metal but they don't match up with anything on top. I'm just a little confused because I thought this would be the easiest part, and I figured I would ask before I go about damaging the sub with a drill. Sub is 12" BTL N2. I've had it for years and never got around to installing it until now.

so i only ask this because i saw this and i have all ways been told to run both coils at all times. but they are saying using one of the two coils just means you can just run half the power to the sub and its no harm no foul. they also said that you can use the second coil with a potentiomoter for a variable QTS system. i would like your thoughts on this, and i thank you for taking time out of your day to answer me.

did it ever have the option of a third slug?

Amp just came in, cant wait for my sub im getting restless...

I know people say it takes about a month of (break in time) before the suspension loosens up so... currently i have about 1 hour of play time Is there a limited amount of power i should be feeding it before i give it the the 1,200 watts daily i planned to? ** Setup ** Sub: Fi 15 BL Enclosure: 3.8ft^3 @ 32hz (ported) Amp: Saz-1500

I just had my highs and mids installed in the truck and now need a little low end. After getting my first pair of Q's from Fi, I'm a dedicated customer. BTW, they are still going strong, now in my cousin's Explorer. Anyway, my current setup is as follows: 2 Focal 165 KF 2 Focal 165CVX JL 450/4 I'm looking to get something that I can hide under the back seat. Here's what I was thinking: 1 10" SSD RF T500-1bd in this pre-fabbed box CRB07-110/112 LINK: http://www.subthump.com/crb07.htm it's the one at the bottom of the page One concern, magnets must be no more than 6.25" in diameter...will that be an issue with the SSD? I'm a firm believer in building my own boxes, but w…

I have a 12" bl and today I am pretty sure I blew the voice coils on it. I was driving around and the sub cutout and I opened the back of my jeep to see that there was smoke coming out of the port. I know for sure that I had everything wired right and i didn't even have the gain up that high( a little over half). I am going to re-cone it but I was wondering if anyone knows what could have caused this so I don't blow the new I get. Thanks

Hey, wuts up. I've got a 12" Bl in a box that is 2.4 before displacement. Right now it is tuned to 30 hz, and I absolutely love it. However, would something like a 35hz or 38hz tune have a higher output for competition? I'm running about 800 watts to the sub right now.

I have a 1992 Mazda extend cab and currently I'm running 6 type R 12's. All sealed. I want to run 2 18's in a ported enclosures. What series should I get? I have been told by Scott I should use the Q's. I'm using 2 Mtx Ta7801's and I'm going to get my 3rd in a couple of months. I only have about 12 to 14cbft to work with. I was wondering should I just get 1 of the Bl's? Run all 3 amps to it?

I am going to purchase some FI subs. I am looking at 2 15's. I have been looking at the Sp415's but have been seeing alot of people have been going with the BL series. Now the BL N series is the neo mags which increase the cost. this is for my daily driver. I like my music loud. Here is some back story to where I am at. I went to a shop that took good care of me 10 years ago but all they wanted to sell me was JL audio. I think that is great equipment. Just not wanting to follow the heard. He sold me an alpine HD-137BT Head unit, 4 gauge amp wiring kit, JL 500/1, Arc Audio ARC 12d4 sub in sealed 1.25 cuft box. I have added polyfill, and had to turn up bass boost to …

So back on 12/7 i received my two 12" Qs and one of them was damaged from UPS! Called up Fi and Scott answered the phone. He told me to just set the damaged sub outside for next day pick up and he would start making a new one. All I have to say is wow, because Fi has already shipped the new sub to me and its only been two days. Thanks Fi your customer service ROCKS!!

i have finally landed on fi as my sub. now i want (2) 18's and i am working with about 10-12cubes in my trunk. they will be powered with a zx2500 and ample electrical. i want to try a new sub so this is what my infatuation with 18's is. i dont think that the bl's would satify me but have also heard that powering 2 btl's with only 2700 watts would be a waste. i want to get the most bass possible from my setup with what i have and want. what would be the best suited sub for me considering that i want 18's?

Got a BTL 18'' and not sure where to make it face. Should i make it face the roof or make it face the back?
