General Fi

thanks to scott and FI.i just won the NSPL amature 1200 amp - 2400 amp current draw class and set the world record with a 163.1 dash and a 163.9 hardcore with bad batteries.FI rocks,great subs.voltage droped to 10.3volts when i burp from 16.7 volts so i'm happy with that.i know it will do a 165+ with these subs.4 -btl's 18's fully loaded and poweracoustik a3000db amps.again thanks scott and FI.

hey scott or nick or anyone that knows.. when ordering a sub is it possible to have the terminals on the sub swapped out with ones that have a bigger hole to fit a larger gauge of wire? cuz i wanted to use 8 gauge on my Q but it wont fit on the sub

Well, I ordered my BL 18" on Monday, 5 days later............yippee! Super fast order. Thanks to the whole gang at FI. BTW... Ive never seen a stiffer sub. gotta love it!

im stoked about my design i got from Pete now the hard part is having it built...still tryna find someone to build it for me cuz i have no expierience with wood work nor do i have tools to cut the wood has anyone on here bought blueprints from Pete? if so how did you like it? well this is goin in a 07 ext cab tacoma

yeah!!! poor postman a heavy box for this little man :bump: my new toy a full loaded BTL 15 . in the 3rd picture the tiny sub near the big boy is a 12w6v2 .... thanks Scott and all Fi team for your serious and speed!!! i have ordered it the 27/07 and i have received it yesterday 9/08.... i live in France...

hi today i was playing deep bass for like 20 minutes and after i gave the sub a break i touched the fi cap and it was pretty warm is this ok?? if i had played it for a lil longer would the sub had blown up???or do i have to break in my sub???im running a rockford fosgate p8002 amp and its sopuse to put out like 950 rms only. I tought a fi could take more than that if i got all the options thanks.

I would like to get this sub reconed to 10" for SPL only. It is rated at 600 watts rms but I have burped it at over 5k no issues. Dual 2 woofer. What kinda options do I have as far as recone goes? Got some pics here:

I like to thank Scott and all the other guys at Fi for having absolutely amazing customer service, and having good quality products. oh ya.. and the pics --Thank you Fi, -James

This is my first box. I just wanted to know what everyone thought about it. It will be made of 3/4 MDF and its for a 15" FI Q. Its tuned to 29hz, and is about 4.5cuft. I have a crude drawing below. Just tell what you think. Thanks.

Scott, How much would 8 Q18's modified for IB (home theater) use be? (shipped to 75409) You know, with the cult discount added in!

Hi my name is charlie , Mike Bartell suggested that i contact you guys. I am building a street max 1-2 truck , and am looking for the most efficent sub i can get as this class only allows a single battery . I'm interested in 2-15" subs that will take burps of 3000-4000 watts of clean power. Many companies have these 20,000 plus watt woofers and i fear that they will be too ineficent for my application. Thanks in advance for your time Charlie

ya, old man Dave the admin of my site, likes to go to bed at 9pm so again, i had to put my vid on youtube....but its ok it will save bandwith for a day i guess. Anyway OMD brought over a friend who gave me a smokin deal on some MDF and him and his wife wanted to hear the Hoe for themselves. You know me, im always down to demo (usually) so out the camera came and off we went

order 2 BL 18's recently. got them both and i got a FI card and 2 Fi stickers but no receipt. i was wondering if you guys ship your subs with a receipt or not? if not its cool, i am just used to getting one in paper form as well as email form. George

I just realized I ordered the extreme leads for my BL 18's that are intended for daily/bassrace, I ordered the subs about 2 days ago. Is it too late to get rid of the extreme leads, or is it not really going ot be an issue? PLEASE HELP. If there is somebody I can contact by phone please pm me with the info. Thanks.

Well I hit my first competition today in Mccomb, Ms..I had my 15" BL in the Trunk with the seats up..Just like I ride around with everyday. I hit a 140.9...in the passenger Kick panel with my passenger window down. Should I be discouraged or happy..I hated I couldn't use my own music and had to use the Usac Cd the guy provided me..Cause I didn't know my noter or that cd that they stuck in my deck...I think If I would have know my note I would have done better...Please give me some feedback..

what is better from any experience you guys have had

Do you think a Soundstream PCA2000D would give me enough power to push two 15" or 18" Qs? If so would I purchase dual 2 or 1 ohm subs? If I wanted to get the full power out of the amp I would have to go with the 1 ohms, but how would I wire them? This amp is only stable at 1 ohm right? Would a .5 ohm load put too much stress on the amp? Any help would be appreciated. Thanks.

Pulled a 145.4dB at 47hz in the kick...Now too bad in my opinion considering the box is 8ft^3 net tuned to 33hz...The subs are getting about 800 watts each.. They definitely had a lot more low end than every other daily driving system that I heard at the comp.. Many people were interested in my subs, and I gave out Fi's website several times! Imagine I could get a 147 or so if I got another box that was more SPL oriented..That may be in my future plans.

To Whom It May Concern (probably Scott), My name is Brad and I currently run a DIYMA 12" subwoofer in a .5ft^3 box. The DIYMA is an amazingly solid sub with HUGE stacked magnets, but its weak point is definitely its cone. Unfortunately, my cone cracked with less than 150 watts and gain set properly. So I am requesting a custom recone kit for my DIYMA. It has a 3" x 2" 4 layer voice coil. This sub is pretty beefy (37lbs) so shipping it would be a last resort. Can you create a new recone kit for this sub? All information on the sub can be found at www.diymobileaudio.com and I can personally talk to the designer of the sub if you need more information. Thank you. -Brad

just wanted to say thanks to scott and everyone at Fi. got my 18 BTLs in today cant wait to install them. thanks again guys!

Soon to have one more 18... Check these videos! Besides the little problem I had with communication, Fi ROCKS! You Tube shrunk the videos and made them a little blurry but you get the pitcher.

Hi everyone i got my fi bl15 today. i just finished taking out my t215 rockford out of the enclosure and puting my fibl15 in, same amp same everything but different sub was used, results were, both subs sounded same to my hearing, great sub fi i played the same songs i play everyday and i tought as if i had my t215 rockford in the trunk but it was my fibl15, well everyone i just wanted to let you know that both subs are really loud like i said very similar on how loud they can get.

hey all, i just can back from my first db drags bass race that was held in hayward, ca. i might say, i had a blast. my car install is still in the works. 18" BL walled. i met some cool guys there and they had no problem giving me tips. BIGGG ups to Christian with the 2 15" RE MT'S. 147.9 db. nice!

well i decided that im goin to buy either buy a 15" BL with only the p chamfer or a 15" Q with the BP option, i have a kicker zx1000.1 rated at 1258 watts total, that box im goin to build is ported and 4 net cu. ft. tuned at 32hz. dont have exact dimensiobs but i will soon. my question is, which sub will perform best with that kind of power. i know that the sound is all box dependant, but which one will most likly get louder, and sound better its my first build, so anything that can get loud and sound good doin it is fine with me thanks

well ive asked this question before but it was with the kicker zx1000.1 that i already have. and now im gettin some money so i can mabe get the kicker zx1500.1 for the BL. i dont know wat size i want to get, but it will be either the 15" or the 18". the options i would get for the sub are the cooling, flatwind coil, p chamfer, and the daily option my real question is, can the BL handle 1500-1700 watts daily with those options?? im think it might be a bit 2 much for it. if theres any other amp that anyone recomeends thats around 1300-1500 watts would be great thanks
