General Fi

i was looking into either getting a 15Q or a 18SSD. I would put either one of them in there suggested box size tuned to about 33hz.....which one do u think would be the loudest?...which one the clearest?

Just checked the website and noticed all the subs are on sale!

I just wanted to give you guys a big for how killer my new BL 12 sounds. This is the first sub of this caliber I have ever purchased. It meets and then exceeds my expectations. Paired with my Sundown SAZ-1500D, it just blows me away

i was wondering if there was a way to find out the shipping with out going through the whole checkout process.

LIke the title says i need a amp for my btl and while i would love the preorder a Saz-2500d i just dont have that kind of money but i have about $350 and was wondering what i should do ????? :puzzled:

I am interested in buying the FI Q 18" sub and i was wondering if it has a sub box included... also, do you ship to Canada? Thanks alot, Mack.

Ok, I have owned quite a few subs in my quest to find the right one for me. I searched long and hard for a '05 XXX 12 and I finally got one powered by a tantrum 1200.1 in a 1.1 'ish cubic foot enclosure. I think it's suffocating though. It sounds good, I just think this sub was more suited for a larger sealed or ported only enclosure. For my vehicle I can only fit a small sealed enclosure, so I was thinking of going back to a Q12. I have a SSD12 with copper coils/BP but it's in my home theatre setup right now. Should I keep the XXX, because it is an awesome sub or go with a equally awesome sub the Q12 because it's better suited for my application? The vehicle is a 2002 …

Hi! So I´m planing to buy my first BTL 18" in summer. The amp that i´m going to use is Alpine MRP-M2000, because I dont live in America, I live in eastern europe and amps like hirfonics or sundown are hard for me to get (only at ebay, but this includes high transport costs and i´m not very rich either). I´m right now upgrading my highs and mids and gona buy soon a new alternator so everything is getting slowly ready by the time. But one thing is on what i´m not so sure jet: should I get dual 1 or dual 2? is there all in all any big diffrence? and how i wire them? I´v read many topics on this forum already, but haven´t got any exact anwer. My amp, what i´m going to buy: 2…

Just wondering if you guys could recone an Orion 15d2 H2? Jason

I got one last week and the other one today. I like how the first one that came in had the black basket, but not a big deal cause it wont be seen. Box build may begin tomorrow after work, but will start sunday for sure. oh yeah, they are BL 18's D2 with cooling, flatwind, universal, and daily and will be run with 2 saz-1500d's.

I'm not entirely familiar with Fi. What I've read however is that they are a high quality semi custom subwoofer. I've noticed the watt ratings are very high for each aside from the IB3. I realize the Q series will probably not fit behind my bench. I have a 2003 f150 regular cab. That leaves me with the SSD our the IB3. I will only push 600 rms to each so 1200 total. JL HD1200.1 The box will be custom made. I have close to 12.5" of room at the floor. One thing that is holding me back its the fact I'm reading allot of revive posts in the forum. Do these subwoofers experience problems or break frequently? Any input would be greatly appreciated and rewarded with fond 'nonsex…

Looking at NEW (not used) vehicles that would be good to put a huge system in. It needs to be under $17,500. So far the only ones that I have like are the 2008 Scion XB, and the Jeep Patriot. Any suggestions would be awesome. Thanks guys. Dan

I'm ordering a Fi BTL 12 for my charger, and have been searching for which amp to get. Thoughts?

i was wondering how muc amplifierpower i would need and whatkind of amp to get?

so i was talkin to one of my buddies that sells car audio in a retail store, and when i told him i got a FI BL he goes so did you get it at the shop in rockford? (rockford, IL). and i go no... i bought it factory direct, the only way you can buy it new. and he said o well theres a shop in rockford that sells Fi. so either hes misinformed or someones buying factory direct then sellin it for a lil more. if this shop is actually doing this, is that illegal?

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

There is a problem with my Q 12, and I need to send it back to Fi to work on it. I got an email from Nick that says: "The only thing I can think that may have happened is the coating that is on the top side of the cone body has delaminated. One out of every 1500 cones or so will run into this issue. Print this email off, place it in the box and send it in to us. When we get it back in I'll check it out or another tech will check it out and see what's going on." So do I not need a return authorization number? I just send the box with the email in it and that's it? Also, does it matter how I ship it? Is USPS fine?

I would like to give a public Thank you to Scott and the staff at FI Car Audio. Once again they deliver excellent customer service. By this i mean, Scott taking time out of his schedule and calling his customers to give them a notice about their woofers! Thanks again FI. Keep up the great work, and continue making the best Woofers Money can buy! Austin Hart

I seen the pic on here about 2-4 weeks ago and I couldn't post at the time my computer was messed up and i can't find the dang post now. Anyways you were doing a build and had pics of it. I remember looking at the pic and could swear that looks like car tune automotive's parking lot. Is it?

Just noticed they are up, but why no 18?

Sent two emails havent received an answer, would appreciate if you guys could hit me up. last comms you were working on getting the dual 2 ohm coils as discussed? thanks...

Hey Guys I have a 03 Yukon Denali that i would like to build a system for. I'm debating on whether four 15 BTL will be better ground pounder then two 18 BTL? I do know that power has one thing to do with it and i will be running two Sundown Audio SAZ-3500D, i will have a big 3, with 2 Alts, and 2-3 Powermaster 3100 and a smaller Powermaster up front. All the subs will be fully loaded, and as far as a box i will have Fisher Customs make a box or Pound that Sound. I am open for all suggesting's to change out any thing or add any thing. Thanks Guys...

Sorry in advance for what sounds like a book but i am not happy in the progress of the install....Here it is old school Eclipse competition cd player 3 sets of RE audio 6 1/2 components pushed by a US AMP md-43 4 channel....2 18in FI BTLS in a 6cuft box (ea) after displacement being pushed by 2 US AMPS md-3d rated at 2000rms @ 1ohm @14.4volts....I also have a 300amp alt big 3 done 5 optima batteries (looking to get XS POWER) and all 0 gauge wire.....Stinger volt meter that is ran to the sub at is ranging 14.7 to 14.0 (i know voltage drop isnt good im getting another 300 amp alt soon) It is loud and hits pretty hard (broke weld in tailgate that holds the handle so kno…

well originaly i was gonna get a BLT fully loaded for daily driving.. BUT NOW im not sure if i should run a BL or the BTL... ive heard of people running the BLs more for daily.... heres what i got a RF amplifier benched at 1,620watts RMS at 1ohm.... and only running a single 12inch sub. currently im running a 12inch REaudio SX sub BUT............ it overheats and STINKS if i pump it to much... which i know IS BAD!!!!!! and well i KNOW im overpowering that sucker.LOL since its only rated at 1K watts. and well iwant more bass but still good SQ cause my subwoofer setup is front firing into the cabin and i drive it DAILY! which would you guys think would be the BEST DAILY DRI…

i have 2 x15inch fi btl on a Lanzar OPTI 6000D, do you guys think im under powering them??? they knock, but i fell like everything i throw at them, they handle with ease, so im thinking of getting a additional Lanzar OPTI 6000D to pound extra hard.... lets me know what you guys suggest?? or should i go with different amps?? Just a thought.
