General Fi

i have 2 fi bl 12's running on a crescendo audio 3k and the fi's are getting real warm...not hot.....just real warm....and i was wondering if this was normal?? also would a crescendo 3k be over powering them?.... im hitting around 140 db. and it sounds great in a 5 cft box tuned at 32 hz...its just getting warm and it worries me...

I have a 1994 jeep grand cherokee and i am having a bit of trouble right now i have 1 Q15 pushin 1500w at 1 ohm and im wanting to throw in another 15 but i dont have the cubic feet i need cause of my spare tire and im not allowed to take it out cause of my parents and i cant find a rack or anything for it should i go with the 2 Q15s or go with 2 BL12's on 1500 watts a piece? Please help and my dimensions are 19h 28d 35w with my spare tire in Price is no factor right now Casey

I know this may sound like a stupid question, but I know nothing outside of Rockford amps. I am getting some BTL's fully loaded and am curious, what would be better to put on each one. The Kicker 2500.1 or the Sundown 3000D? This is for daily driving. Would the extra $400 be worth the extra 500 watts per sub? How good are Sundown, heard Kicker were good. Thanks in Advance

I ordered my second pair of SP4 15s last friday and today the order status switch to "manual verification required". Im an electrician and work out on the road all week on the current job im on. Nearly impossible for me to get packages at my address, so i had them shipped to my girlfriends house. If someone from Fi wants to vall me, my cell phone # was included with the order. When i ordered my first pair of SP4s i tried to do the same thing and they were shipped to my address anyways. They almost ended up getting sent back. Life on the road...it sucks! So please get ahold of me Fi!

Fella's i was wondering about the decals from FI. I want to purchase the white decal so it will show on the rear window of my car but which color do i choose on the page here to get the white decal? Also the ones they send with your purchase dont work at all. How do you get the to not show the rear when installing them on your car?

do I have to worry about window damage with two 12" fi bls?

Just out of curiosity, what is the operating temperature of the magnets in the BTL N2. I'm sure Fi researched this, but I was just curious. From what I can gather, the operating temperature for ferrite magnets is around 300*C, but the operating temperatures for neodymium magnets is quite lower (source). What grade exactly is the magnets used in the N2? As in, is there a letter following the "N48"? I don't know exactly how hot the magnets get, but I read that voice coils can exceed 150*C. Thanks!

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.

Did a revamp today of my pop's explorer. It had 3 RE XXX 15's. We swapped out for 3 Fi Q 15's with the BP Power Package, and he loves the new subs. Old Setup New Setup Please excuse the mess, I had a little grinding to do on one spot for the subs to fit normally, instead of inverted, and I really like it alot better, and so does Pop. It looks alot cleaner to me, the nice curved transitions look much much smoother. Here is the list of everything in the truck.

im doing an install in a 2000 expedition im going to use a MM1400D and a MM100.4, the budget is kinda tight since he wants to spend $1000 for everything. it's going to be for everyday use only and never see a mic. should i run 4 kicker cvr 10's or one 12" Q ported? and why?

Its been 2 weeks sense i bought my sub and i still haven't got a email or anything so i was wondering if everything was ok. My name is Kasey Cavyell.

Hey guys before i get completely torn a new one the dimensions of this sub arent clearly listed on the website. I am working with very marginal clearance and i was hoping someone could help me out her. first off im looking to do 2 SSD10s under the back seat of my truck so space is tight to say the least. Does anyone have a picture of these or could help me with dimensions? Things that i know, the mounting depth is 6 inches. the only pictures that i saw had the mounting depth closer to 7 inches. When did they redesign this sub? secondly i know at the widest point the magnet is 7.5 inches in diameter. Can someone please help me with the dimensions of the magnet. The a…

I have an audiopipe ap1500d running 2 fi ssd 12's. when i turn my music up and the bass sounds really good it will just cut out and will turn back on when i turn it down, any ideas?

I have had my BTL for less than 1 year and it is now dead. I had it powered by a zx2500.1and it is in a properly sized and tuned box.. NO bass boost, subsonic on, gain 1/2 way up. The spider is ripped a little bit but I can not see any other damage. IT does smell funny. I am a responsible user and did not abuse the sub whatsoever. I have been installing and using car audio for years,. Does Fi have some kind of warranty, Can I send it back for a recone? I would appreciate any input. THanks

Ok heres the story, my back window had major bubbles and i dont know why, its been perfect for 10 years. Well i got tired of it, plus when the sun gets in just a little you can totally see the ugly rear of the wall which is fairly "raw" . Sorta embarrassing to roll my honda out, hella slammin, tuckin 18's..........but the worlds ugliest tint and behind it a raw backside of a wall. Well today, i broke my back glass out for the glass guy and it only took one sub! Can you believe it! heres the vid: dPApRN97WRs

Should I be taking it easy on my 2 brand new Bl's until they break in a little or does that not matter? My old setup seems like it put out more spl and it was less power.These do sound good I just need to tweak the settings more then before.I was running 2 RF T0 12's with 1000bdcp,Now I have the 2 fully loaded BL 12's dual 2 wired to 2 ohms at the 1500bdcp. If I bump the BL's like I was bumping my old subs is it going to hurt them since there stiff as shit? I don't wanna screw myself out of some new subs I just spent $800 on.

Hello. I have only recently entered the world of Fi. Before the BL came out, when I was first looking around, there was another line of subwoofers. Are these still available thru Fi or not? If so, what are the specs on them? I did not think to record them before the X disapeared from the site. Thanks for the help! Ben

hi everyone. I would like to make a purchase for BTL 18" 4000 Watt X 2. So i want your advice which is the most suitable amplifier and mono amplifier to support it. Need help..

i have a fully loaded bl15 and i need an amp, wich amp would be good for my sub???

So yesterday I finally got around to making a new box for my 12'' Fi Q D2. The box came out great, but when I went to put the Q in I noticed one of the tinsel leads was broken at the end where it connects to the terminal. I'm not sure how or when it happened. The gain on my amp (US amps XT4000D, 1500rms @ 1 ohm) is set about half way up and the bass boost is off. My question is what can I do about this? repair it? send it back for repair? Any help is appreciated, thanks

well, its about time I get a new subwoofer, my 15s are completely worn to shit (bet you've never worn a driver so bad you can make the cone bounce by pushing it in) they sounded so good 10 years ago, I dont know what happened. anyways, so I've got 4 computers imma sell to get a fi, that means 400 to 500 dollars for a new setup. What should I go for that wont kill my price limit? (Please note, Shipping is a factor here, and I want an 18, so subtract 40$ from the total money for wood. yadayadayada) Thinking about maybe a Fi Q 18 fully loaded... but could I get a no-option BTL for under 500 shipped??? (best to put it here, you people know how much these drivers weigh, and if…

i think that this question will mostly be aimed at Scott....i recently purchased a "damaged" brahma mark II 12"(i think, no idea which is which but i am tol the mark II) that wasn't damaged at all really...just had to fix a bad glue joint and it works perfect now... 30 bucks and a 2 dollar tube of adhesive isn't too bad, but for my real question i bought it with the intentions of re-coning it to an 18" Fi Brahma Hybrid of some sort.... i was wondering if it could be done...or has it been done? i was thinking a dual 2 ohm coil with at least 1100 watts power handling... i still want to retain good sound quality also...not sure if i would want to do it ported or sealed thou…

well i have a 18" btl dual 1 ohm fully loaded daily sub. i know this sub will rattle the hell out of my 86 Monte but how will it do with music sound quality. she will be in about 5-6 cubes at 32hz. and powered at 2300 rms. now would i be better of switching out my 2 of my 6.5's on the doors for a set of components and then the other to 6.5's for a mid bass. i also have 3.5's in the dash 4x10's in the rear deck and a set of 6.5's in the rear interior panel. so i would think with those speakers i could get a good sounding system and turn the bass down low. if my thinking is flawed sorry.

car is a 02 cadillac deville, 1 15 d1 btl on strapped saz1500ds, subsonic all the way down to like 15, gain at a little lower than half. box is a chambered t line built by rich which i think is in the neighborhood if 30-36 hz tuning. i have a EQ with 8v preouts, HU is a max675vd. i think i need some guidance to set amps before i order a recone or try to replace the lead itself. volume on the hu 27 out 33... but the volume on the EQ is almost all the way up.

I sent my subs out to get reconed by Fi. I bought the 2 reconing kits and what not but my question is do i have to pay for the sub to get returned to me or did they add that into the price. I did select the option to send my sub in.
