Fi Technical

I have Term-Pak and am looking at the graph for a box for my BTL It looks horrible. Is it just me or does the sub just plot poorly? I used the specs off the site. I'm using a model of 4ft^3 @ 32Hz

Ok so im about to order 2 12" Fi Qs and just want to know what setup i should get. im thinkin on getting a JBL GTO14001 amp for it, is that ok? also... i need to know if i should get an extra battery or cap for it, if so what kind?

I want something that will flex glass but that i can us daily. i was sold on the btl 18" but will it handle everyday abuse? Any help would be great thanks

Allright i got my btl in and the dustcap got hot really fast and i mean hot hot i have 8ga wire running to the speaker and 1/0 ga ran to my optima back to my kinetik 2400 and ran it full tilt and this happend its a duel 1 fully loaded and it is in series to make it a 2 ohm load the amp is a Rockford Fosgate t2500.1bd everything seems to be fine i mean i have not "Broken" it in yet..need some help does it matter which terminal i use to run series?

So i was listening to my system today and i put my ear next to the box and i heard some sort of slapping noise. I know this cant be a good thing but who knows im a noob. I have a 12'' Q with the BP option being powered by a hifonics bxi1208d. I have the gain at half way and the sub sonic at 32 hz and the low pass at around 100 110. I have a down firing box, 2.5^3 ft tuned to 32 hz. Is the sub supposed to make this noise or what? thanks for any help

Ok, I am a ported enclosure built from pound that sound for 2-12" Fi Bl subs. I built a cardboard box like he asked as big as possible to fit in my trunk. It ended up being 39" wide x 13" Tall x 15" deep. This was sitting on the ledges on each side of the trunk and the spare tire hole being empty on the center. The box has to be dropped in from the top and has about an inch and a half gap on the top, and the side facing the rear of the car. Will this be enough space for those subs? I notice it asks for 1.8-2.5 per sub so I think I am a little small unless I would extend the bottom center of the box down into the spare tire well. HMMMMM?

I have 4 18 inch fully loaded BTLs that I will use for a daily driver. Can anyone help with how many cubic feet each sub should get? I want a ported box and will power them with 2 jbl a6000 amps. The manual says 5- 8 cubic feet but what size should i go with?

Ok i have a 03 silverado extended cab and im wanting to put either 2 12 q, or 2 ssd under the rear seat in a sealed box that has .82 airspace for each chamber and a 7 in mounting depth. i dont know what subs would be best because i really want something that would make people stare lol any advise would be greatly appreciated

Alright so i have a BL 15 in my car right now. When i get money i plan on buying another one. But the one i have right now is D2 instead of reconeing it to make it d1 i was thinking could i just buy another D2 and then just buy another SAZ- 1500d?

I have 2 12" Fi SSD's with copper coils coming soon and I need a box for my Charger and found this. http://cgi.ebay.com/2006-Dodge-CHARGER-SUB...%3A1%7C294%3A50 Would this box be ok to use or should I have a shop make one? I also found a ported one http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=21319 I mostly listen to rap but also listen to rock, death metal, etc. if that helps

I have a 94 Ford Lightning and currently have a Alpine CDA-9883, Kicker KS components,4 gauge wiring, 12" L7 and Hifonics 1508D amp. Im wanting to get as much bass possible out of a single cab truck without cutting my truck up. So im looking into the BTL 12".Should I go fully loaded? I will be playing this sub everyday. At 1st I will have it running off my Hifonics amp putting out 1500rms at 1ohm. Do I need the dual 1 or 2 ohm to run it at 1ohm load? Then when I get some more money ill get a better amp. How much power can a fully loaded BTL 12" take daily? Im thinking about the Power Acoustik BAMF 5500 amp putting out 3200rms at 1 ohm. The biggest box I can fit in my tru…

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 …

Gday all I am running two FI Q 12" D2's in a daily driver with a box that was built for it by a local car audio installer using a single round port. Sounds reasonable but no where near as loud as I expected from these speakers. I am driving them with a Hifonics 2k rms amp Boot mounted Optima inline with another optima under the hood. Also have a 2.5 Frd Cap. This is a boot mount install in a Aussie car Called a XR6 Family sized four door sedan.. ATM I have the speakers behind the back seat pointing into the car and the port facing the same way. Metered this setup at 132.5 before i upgraded the batteries seen alot better scores out of single speaker setups with similar siz…

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…
