Ok well I figured I would come here since Fi does not seem to like to email there customers. I bought a Fi BTL 18 fully loaded from their website last summer and for the past 5 months it has made a popping sound. It would do it pretty randomly but usually around half way up. Well after about 5 months the sub seized up. I figured it was the voicecoil, had probably come apart.So I begin removing the cone then the spider when I see that the voicecoil is fine. It was the motor, it had been rubbing up against the voicecoil eventually causing the sub to seize. I pulled out the voicecoil and the motor just snaps against the side what a headache! Im looking at the basket now I …

how much airspace would you guys reccomend for 4 x Q 18's in a sealed wall?

I have 2 fi Q 15's (w/ BP Power) in a sealed enclosure (seperate chambers) in a 2000 dodge dakota. Each chamber is 2.5 cu.ft after all displacment. I have my gain set on my amp (AQ2200D) to 4 V the same as the output of my head unit (Pioneer AVH-P5050DVD). My bass boss is all the way down, and so is my subsonic filter. The max vol. on this unit is 40 but i usually listen to my music with the vol. set to about 24-26. I just installed the system about three days ago so am still "breaking in the subs." On my way to work lastnight, i could smell whats seemed to be something buring. All my bass levels are set to either 0 or normal. Is there any reason for this to happen. I kno…

I see pictures of raw boxes with Fi 15s and up in them and they all have double thick (looks like) 3/4 inch mdf. So is this really necessary? And if it is, what about the sides, do they need to be doubled to? Also whats the best type of bracing to use?

i have a center console box for the rear of my crew cab titan.its 1.7 net and i want to do 2 BL 10's.after sub displ. its .7 per sub.my port is an aeroport.3"x10" so that 30 sq.in.will this work and sound good?thanks

whats up i was wondering if someone could tell me if a 5.573 CF. after port and sub displacement enclosure with a port thats 12.5"s tall 5"s wide 20"s long tuned at 34.73 hz. sub up port back would be a good box for a 18" fi bl or would i be better off going with a 15" bl let me know thanks.

alright im going to be ordering a 12 Fi fully loaded..and i plan on running around 1500rms at 1ohm. do you think i need to upgrade my electrical system. i have a ford f150 with a 130 amp alt...what do yall think???

can anyone tell me how many watts i should run to a fi bl 18 and wether i should go with a dual 1 or dual 2 ohm.... and also what is the best hifonics amp to run it on?....

ok so im going to be running a 12 fi bl on about 1300 rms...which gauge should i use 4,2, 0.. i have no knowledge of amp gauge wire so anything will help...

I was looking at the options for the new 12" BTL im getting and i cant seem to find anywhere on the site that explains what the "HiXmCoil" and "I Heat Ring" do sorry if i overlooked something thanks for the explanations in advance. Tyler

Hey everybody i was wondering if I will get a better spl level if i face my sub towards the front instead of the sub facing the rear of the trunk.... My enclosure is 3.0 cf3 tuned @ 35 hz... Fi BL 15.... the car is a 05 kia spectra lx

hi all i have been planing a blowthru on my 01 tacoma using two fi q 18s and two soundstream trx2000ds. now i have come up with a few ideas for a box but was wondering if there were any pros out ther that would like to offer up some advice. i was thinking of having one sub on either side with a center slot port ond a combined volume of 22 cubes tuned to 28 hz. also i have heard pete from ttb has some great designs but he hasnt gotten back to me yet thanks

Hey, I've got a MA Audio HK12X2 that is in need of a recone, I burped it once in '04 finals (it was it's first and las burp) it's been sitting since. The recone will need to be for spl Application, 3" VC 3/16-1/4" gap I'd appreciate any info. Thanks

sealed up at the kicks i hit a 144.8 with my single 12" BL. at the dash sealed i got a 144.3 the meter was an audio control. and i lost 1 db when i opened the window. song i used was airforces and hypnotize. they both did about the same number. Basically what i want to know is if this is a good number for a single twelve trunked car? could i get it higher by using a 50 hz test tone or somthing?

I have a kicker ZX750.1 on the birth sheet it says its rated at 932 and I really want the 12'' BL So before i buy the BL i just want to know is this not going to be Loud enough due to only 932w? I really want it to hit hard so i can really Feel the bass..

I know no one probably knows really for the 09 lineup but would the BL 15 really get THAT much louder than the 12 if they were both fully loaded? Or would it be a noticeable difference? I want to know if it's worth waiting however much longer for the 15, or if i should just order the fudgeing 12 cuz im sick of waiting lol.

hey guys so i bought 2 15 bls last month and have installed them in a 9.5 cubic ft box with 102 sq inch port and have 2 amps at 1150 rms each going to them. for the first week it pound ed ma were i oculdnt even swallow. then just yesterday i brought it to a shop to get it db tested and hit a 150.9 with eas apparently says the guy. but i noticed after that the ext day t wasnt as loud to me or hit the notes as deep. did something happen to the subs or is it just my ears and body getting used to it. plus i dnt know wut to smell for or here? i know this sounds stupid but i dont want to do damage. replys would be greatly appreaciated!!

I have two Fi Q 15's and would like to know whether to go sealed or ported? I love tight bass and also love the sound of a ported enclosure. I have the space for the ported enclosre (6.2 cu.ft)and i also have the space for the sealed enclouse. I love both sealed and ported enclosures. But which encloser would be the best for good sound quality and will also get loud. Any input is welcome. thanks

Since I've bought the sub,I noticed they sell a fully loaded BTL.My sub only has 2 magnets.Is my sub the 2000w rms model,and what year sub do I have.my ride

Just recieved my FiQ12" need some help on box ideas measurments.. etc.. I drive an 06 Nissan Xterrra. I would like to build a box the slants at an angle "towards" you following the countour of the back seats to.. (larger on the bottom , to smaller on top with the front being straight , facing the back) if that makes sense...Ill post a measurement of the height of the back seat at the angle but if any one is an SUV owner out there you know what i mean... i hope...that makes sense... I am assuming an angle on the back of the box doesnt make a difference.. its the amount of air inside.. I also need some recomendations on terminals for the box.... I am open to alternate id…

I am looking for sound quality mostly, not worried about if the bass rattles my car apart. If I go sealed would it be terrible if I went prefab from online? and if I went ported I am thinkin about 2 cubes at 30 or 32 hz. how big of a difference would trupan-lite over mdf make? thanks all

I was told by other members of this forum to email Fi about this topic, which i did, but I have not got a reply and it's been about a month since i sent the message. Any chance Fi still has recones for D4 X 12's? Or should I invest in an Ascendant Assain? Also, its just the leads. I've replaced the leads on one of my D4 X's already so i know i could do it, but i cut through the cone getting the dustcap off. Maybe I could ship the sub to Fi to get it repaired since they deal with things like this all the time? I'm just exploring my options! Since it's been so long without my sub, I am willing to repair it myself again. All I will need is four leads and a dustcap. Depe…

I am going to be ordering a 10" BL and was wondering which to get? Should I go with the dual 1 or 2 ohm? I plan on running it off the saz-1000d. If I get the 1 ohm, that would bring it down to .35 ohm, but with the rise, shouldn't that bring it back to almost 1 ohm? Just wondering as the amp reports that it is only 1 ohm stable. or would it be better to go with a Mmats 2100.2 and get the 1 ohm and wire them in series? this isn't something I need ASAP, but any ideas would greatly help the process. Or... another option is to go with the dual 1 ohm wired in series and go with the saz-2000d. Ideas?

I just got a 1998 blazer (4 door) and transferred over my Sundown Audio SAE-1200D and 12" BL from my 99 grand am. The box is 2.5 cuft AFTER sub and port dislacement, tuned around 32-34hz (can't remember exactly off the top of my head) I have upgraded the BIG 3 with 1/0ga wire, ran conduit along the frame rail with 1/0ga to the amp. In my grand am I LOVED it, but now in the blazer it seems to be lacking... not sure what exactly, but it doesn't seem to rattle my noggin like it did in the grand am. My question is should I look at building another enclosure that would work better for the blazer? If so, how many cuft? tuned to? how should the sub and port face? Or is the blaz…
