Ok guys i wanna get 2 Q series 12" subs my only problem is i dont what dimensions to use for a ported box and lso a sealed box. If any of you know please share im trying to either et cut out sheets for them or get the dimesions needed thank you. I was told to ask JBLCamry but i cant find him thanks ahead of time.

I have a old kicker SX 1250.1 amp. its rated 1250+ at 1 ohmn. my question is what would be better for the sub and amp? 1 or 2 ohmn's? the 1 would be getting more watts so it would be louder but if i ever switch amps will that effect the 1 ohmn? the sub would be a 12in Fi BTl N1 sub, its rated at 2000rms, idk which to get 1 or 2?

Hi guys, I was looking at the cut sheets for the fi Q 12 ported which is tunes to 32 Hz, and have a few question. what would I have to do, (if it can be done) to the same box, to tune it to 28 Hz? Or Would I have to build another box? Would you recommend tuning it to 28 Hz as opposed to 32 Hz ? What are the prows and cons? Thanks, Shopvac

After first seeing the specs on the website, I noticed there are a few necessary specs not included. #1: I noticed the xmax, but nowhere did I see the xlim. #2: Recommended type of port(s)? (shape/size/depth) If I list the specs of my vehicle, maybe someone can get an idea and throw me some info. If any other info is needed, just ask. 1995 GMC Sierra LT ext cab 6.5ft bed. Rear seat bottom and back will be removed. .75" MDF enclosure with internal dimensions of 45"W x 30"H x 25"D. Subs will be up-firing. Should ports be front, rear, up or side firing? Where should the ports be located in terms of speaker location, between subs, at corners, etc? I will be aiming for…

Hey, I've been looking at Fi car audio for a while to help fix my BMW's horrible lack of bass. I was originally looking at the 12" Q but after reading around I decided that the BL would better suit my needs, I now am at this problem I know my trunk can fit the optimum box dimensions for the 10" and 12" but I dont really want to sacrifice all that space but then I want it to also to be hitting pretty hard. Also whats a good amp recommendation for the best price/performance

So the plan is to buy 2 Fi BL 12's dual 1ohm, with the cooling option and flat wind what is the new rms power rating (approx) I know it depends on the enclosure so optimal ported at 33hz. In a Jeep Grand Cherokee I plan on running the two on either a Re audio VLX-3DE or Hifonics BRZ2400 (2400 watts)

Like the title says can i put a bl in a sealed box. I know it recommends a ported box but why cant i put it in a sealed box? thanks ps. I already have them before when I had space for a nice size ported box.

Hey, I'm wiring a 2ohm DVC Fi Q to a Sundown Audio SAX-1200D. Being a monoblock amp I don't know how to wire this properly. I've checked quiet a few of the websites with wiring diagrams but none of them are showing how to hook up to an amp with double connections ++ -- All they show are mono or multiple channel configurations. Currently the sub is wired following this diagram http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/1DVC_2-ohm_mono.jpg Looking directly at the side of the amp with speaker connections, brackets = [wire] [+] + [-] - I think with the way I have it wired that it's running @ 4ohm. The goal is 1ohm.…

Hey guys! I was wondering what any of you with a Q 18 set your crossover or lpf to? Also what type of crossover? Right now I have BW and LR filters to choose from, 6, 12, 18, or 24db/octave and 12 and 24db/octave, respectively. A simple frequency recommendation would be great though, hehe. I have tried many values from 70 to 180Hz but can't really decide. Are there any tests I could do to help me decide? Right now I have it at 127Hz 24dB LR which seems to be fine but I still feel indecisive. Thanks!

I'm going to do my box at 8.8 Cubes with dicplacement I'm looking close to 8 cubes. 8.5 with the sub and I'm thinking about the port. Should I do a 4x18? or a 5x18 tuned to 28hz.. Thanks guys

I think it's just me, but there are some random gaps if you will. I have some pictures from my slr that i'll upload in a while. Just want to make sure theres nothing bad. Thanks

A lead came off my BTL as I explained here. Wondering if this lead is the proper size/wattage...or possibly what you would recommend. Love my sub...thanks for the help! ~Abstract~

hello, as stated i am in need of a box design. i got 1 18 Q and a aq1200d amp and it will be going in a 2000 grand prix. so i have about H = 16". width = 30". and length = 32" of room for a box but i do not know how big to make the port. i am going sub on top and port at back. suggestions needed.

Here's the deal... The car is a 2001 chevrolet s10 blazer 4 door and i currently have a 12in l7 kicker (4ohm dvc) with an enclosure of 3.75^3.ocft @ 35hz... powering with an Sundown audio saz1000.1d the sub is currently gettinh 600rms on a 2ohm load... i'm looking for something with quality and want it to get low and loud. i've came to a conlusion to go with an Fi q, the only problem is i don't know whether to go with a 12in fi q 2.5cft@ 32hz or a 15in fi q with an 2.6cft... not sure of options since havn't made up my mid on what size nor know what options to go with with either setup... i will be running the amp on a 1ohm load to feed 1k rms to this fi q. i'm leaning mor…

I bought a pair of the 10" BL's with the SPL option a few years ago, maybe 4. I have no use for them anymore as a burp only sub. Is there a way to change them to a musical and burp sub without having to change motors? I know the gap is pretty tight since it's a burp only sub, just not sure if it's as simple as buying a new recone or if it's more expensive.

Hey guys, Finally ordered my Q, 15" w Cooling+Spider... so pumped! but now I have a dilemma I have ported box that is built to the specs of 3ft. cubed @33hz, but wanted to know if I will hear any audible difference by going to a 3.5cube @33hz? Is it worth it for the Q? Goals are just to have the loudest setup given my amp (1500d sundown), sub, and trunk space Just wanna know what, if anything, i would be missing out by keeping the box at 3 cubes thanks

The motors on these woofers look almost identical. I know both woofers are made out of the same build house. Is there any difference in the motors? I know Xcon is more of a sound quality woofer, Im a owner, and the BTL is more of a SPL woofer. Is it the soft parts and the coil that make them sound different? Please excuse my ignorance on the subject.

I purchased a ssd12 not too long ago(3/15/10) and it has stopped working. Amp is fine good power still. When it does feel like working it sounds like its bottoming out even when its barely on. What is the procedure for something like this? Thanks in advance!

ok so I went and measured my trunk, the room I am working with is 36" wide, 20" deep, Now at the front of the box the height is 17.5" and at the rear the height is 14.5" Can anyone design me a box with 3.9cubic ft?? or where can I go to see some cut sheets of how this will look, I know it will be slanted front the front to rear.. this will be for my Fi BL 15.. thanks for all your help

hey guys im deciding on what to get in my setup but i was wondering about the Audioque AQ2200D i was thinking of running two of these with 2 FI BL 15s. on the audioque site it says if your not careful you might burn a coil or fold a cone ... i know the FI subs are tough but how do you think they will go. Thanks

I'm about to get 2 Q 12's with cooling and spider but what is high QTS? i know its for a sealed box only but would i be okay running them in a sealed box without high QTS?
