Fi Technical

I recently bought a 15' Bl and had a enclosure in mind. The enclosures dimensions would fit inside my car, so I went ahead and bought the 15' Bl with the cooling option. It arrived a few days ago and I was super siked. Then I realized how would I get this box into my 99' Grand Am GT. The box will not fit. (This one http://www.bestbuy.com/site/olspage.jsp?sk...=1218009774927). Now I'm in a pickle. I have found another box that is ported,that i think will fit in my car. It is on the small side as far as cubic feet wise though. link to it --->http://www.bestbuy.com/site/olspage.jsp?skuId=9026797&st=15+in&lp=4&type=product&cp=1&id=1218009790168 Will th…

can anyone tell me if i can fit 2 BL 15s in my trunk the biggest dimensions i can fit are 17" height, 27" depth, 37" width, i dont think i can do a trunk facing enclosure but i think i might be able to wall off at the back seats. Running in a 2001 Oldsmobile Alero sedan Cresendo bc2000d at .5 ohm

Ok so i have a FI BL 15 Fully loaded powered by a Sundown SAZ-1500d. Ok so anyway when i play some music loud i hear some weird sound like the sub it bottoming out but i know its not becuase its not moving enough to bottom out.

well ive had my btl in for a few months now, but now, i want something louder. I also want to free up some room in my backseat, just because my current box is HUGE back there. what im wanting to do is recone my 15" fully loaded to a 12", and build a better/stronger box for it. i plan in the future getting a second 20.1, strapping them and adding a couple of batteries. I really want to break 150 on music, would i have a possibilty with a set up like that? i know its all install dependent, but with a good install, could that be possible, without having a fart box?

would anyone recommend running 2 hifonics brutus 1606d mono class amps to a 15" fi btl sub at 2ohms and connecting each voice coil separately if no. why not?

I am new to car audio and need some help. Im not sure if i could fit an 18'' Fi BTL will fit in the trunk of my Toyota Corolla. Thanks

Hi, I have had my BTL 12 for several weeks now. Its fully loaded and only receiving around 1000 watts rms (PDX 1.1000). The enclosure is 3 cubes after displacement at 34 hz. On certain notes, i hear a popping noise. The notes are almost always higher notes. The spiders and leads look fine, but i dont have much experience with them. Is it possible that i am reaching the mechanical limits of the sub in this box at less than half power? Amp is not clipping to my knowledge. Voltage is stable when the noise sounds (less than half gain, no bass boost). Oh, and the popping is only heard at half volume plus. The sound sounds like its coming from under the dust cap. Any i…

Hi, i've been passive for a few months right now. My last system was one 15 btl dual 2 on two RF t20001bds @ 2 ohms with few kinetiks and 300 amp alt. I think of adding another btl 15 but keep the amps, one btl strapped to 1 ohm and one t20001 @ 1 ohms per sub. Do you think this would hit harder or should i just recone the current btl to dual 1 to use the full power of the amps.... Patrick

Im running a single sundown 1500saz for now, but might get a second in the future. My vehicle is an ex. cab S10 that I can fit roughly 7-7.5 cube ported box in. Im wanting the most SPL out of my setup and I am comparing 2 15" SSD's against a single 18" BTL. I know my 1 amp wont push the BTL to its limits, but it should do very well with the SSD's. My question is will I get the loudest results running the Sundown at 0.5 ohm (18-1900 watts) with 2 15" SSD's or a single BTL 18?? thanks in advance! Cody

Here's my box I made for my new FI BL 15. This will be going into my 2014 Focus ST and will be driven by a Brutus 1200.1d at 1 ohm. Box is 3/4" Oak Plywood and is on the high side of 4.2 cubic feet. It is stained with Minwax Cherry Blossom stain with like 8 coats of poly. Empty Soda can is for size comparison. Has 14" long 6" psp aeroport tuned at 32hz. Turned out a little more Purpley/Burpley than I initially wanted but I said to heck with it and left it Burple. Looks a little more reddish Burple in the sun than in this pic. The shade.........It's growing on me. I did a little shake down run with a old RF Monoblock amp I had running a 18" obsidian. It sou…

I just bought a 15" FI-Q and now I am debating between amps. I looked at a high end: memphis mcd1000, Rockford Fosgate Power T10001bd, Low end: Hifonics BX1206D, Memphis PRD 1000.1. Any suggestions for an amp..or any listed that I should go with? Secondly, I am unsure if I should go ported with a low tune of 28-32hz or just go sealed with it. I want it to bump hard, deep bass and want some sq out of it. SO will that low tuned ported box give me a good sq but also hit hard?

Hey all. I'm going to build a sealed box for my 10" Fi Q woofer. It says the mounting depth is 6.5" for that driver. How much clearance should I have behind that woofer in the box to ensure adequate ventilation? I want my box to be as shallow as possible to save on some trunk space. Thank you.

Does Fi offer a recone kit that would fit on a MA Audio 1800XL? If not, who would? The recone kit would have to include a new basket.

I am thinking about getting a pair of fi q 12's I am going to be running them ported in a daily trunk setup on a Saz-3500v2. I am getting the cooling option for sure but for I am not sure if I should get the extra spider & the internal lead options, I am thinking no on these options but I would like some opinions before I drop my cash on these subs.

Hey guys So here goes Have my two Fi Q18's off a JBL BP1200.1 When i first installed them they moved in phase perfectly it was actually awesome to watch ! Now they dont and output is down noticably, So.. .. I pulled each speaker out of the box and checked for physical damage, none, no burnin smell AT ALL and no loose glue that I can see, second i Tested each speaker on its own, works fine, i checked coils, fine they all show up the same. Im runnin dual 2 ohm in series parallel and am getting 2.2Ohms on the VMM for my final load , fine.. Speakers were making a funny noise sort of a raspy sound right after they stopped working in phase... Unhooked em right away , checked, …

Both setups will be run off of a Sundown Audio 2000D amp. I only have a space of 1.1 cuft per chamber to work with. I mostly listen to rap and want these subs to be able to lit the lows well.

what kind of enclosure am i looking for? i have a 1995 lumina, and now im seeing what kind of box i should go for. ( i have a very large trunk. ) i think my MTX JH55 is a 4 cube box. and i still have room for a little more, could someone post the exact and best enclosure for the FI BL 15? and is there any very good box builder for xp or vista? also could i get exact specs for the 15bl with cooling, daily, universal, and a red dustcap. ALSO would a hifonics 1200ixd amp wire at 1 ohm be ok to power this amazing sub?

Ok so i have had my Fi BTL for a cppl months now and i was bumping it today and the Dustcap flew off. Does my warranty cover repairs on that? if so how do i go about getting it fixed?

I have the following system... '96 Jeep Grand Cherokee 2 18" Fi BLs 2 Rockford Fosgate T10001's 1 Rockford Fosgate p500-2 1 Pair Infinity Kappa Perfect 6.5" components 1 Pair Alpine Type R Coaxial 6.5" Lots of Lightning Audio Wire Alpine CDA-7897 Head Unit + 6 Disk Changer 225 amp Excessive Amperage alternator Box tuned to about 34 hz My question is, I cannot for the life of me get my subs to play the same. They are phase, wired with 8 gauge, and the polarity is correct (as long as the subs are labeled correctly). I have the amps set for master/slave, set to give each sub 1400 watts. Does anyone know what could be causing this problem?

My buddy bought a Triple stacked BTL (first gen??) and I currently own the 2010? UFO style BL (without red sticker on bottom of magnet). My main point is will it be worth it to get his BTL? Im not sure how much of a difference the generations actually make but I'm assuming a newer generation BL will perform the same as an older generation BTL. Opinions? Im going basically for SPL and the box is 3.75 ft^3 @ 32 Hz. Please no flaming. Im already one hundred percent satisfied with my BL but just wondering if the BTL will give me that extra boom boom ya know. Ohh, and both the subs are fully loaded 15's and will be ran off of my RF T-1000Bd.

Hey I was talking to Scott about reconing my tc9. he said he could, but i think he has been busy lately so i'll post this here lol. I have the address still from and earlier recone i sent in, can i just send the sub in with a little note stating what i want with my contact info?? or would there be something else that i need??

Recommended box size and tuning for a single fi btl 12 running off a crescendo 3kwp at 1 ohm for a 03 crown victoria.

Ok I've been trying to get my subs reconed for about three weeks now, I already know that they wont be covered under warranty because I overpowered them, but i have the money to get them fixed so if someone that works for fi could send me some info to get me on the right track, i would greatly appreciate it. Subs are:( 2) FI Q 15's D1 w/ BP power. THanks

I am curious as to about everything about the Q. I am newer to higher end car audio and will be doing something similar to my friend, who I think is getting 4 15" BTLs. How much SPL would 3 or 4 15" Q's produce? I want something that can cause tons of vibrations, maybe flex, but still sound amazing. not quite sure what to go with yet. Any help would be great. I would like the BTL's, but I think they would take up to much room in the bed of my truck, but I have yet to take solid measurements on how much room I actually will have. I am hoping to take up no more than about 3/4 of the bed, this including amps and extra batteries. Or suck it up and go with the BL or BT…

I am going to build a box for a 12" bl or a q. My interior box volume (after subtracting speaker displacement) is 2.1 cu. ft. What kind of port and what dimensions do you guys think I should use . I haven't decided which sub I'm gonna buy yet. Also feel free to leave some feedback on the two subs (is there really a huge sq loss with the bl or is there a substantial bass level loss with the q)
