Fi Technical

got my sub couple of days ago and need a design. its going into a 99 cadillac escalade so theres plenty of room... can you guys help?? listen mostly to heavy rock and some rap.

I'm currently a college student majoring in Electrical Engineering. A few years back, I competed in roughly about two MECA competitions as a hobby. The experience was great, but short lived. With my new schedule, I'm able to juggle classes and a job. With that said, I've decided to go back into competing so that I can have something "fun" to do outside of studying hard during the week. I'm specifically looking to compete for SPL in MECA. What I buy from Fi will strictly be based off of the new point system for MECA. There are several classes, and I'd either like to compete in either Street 1 or Street 2. Street 3 is simply above my budget as a current college student. The…

Just made a topic so you don't have to scroll through pages to find it... Ok first things first. The test was done in my car with my equipment (in signature). The box is 4.5 cubic feet net tuned to 32 hz with 57.25 in^2 of port area. Subs: 15" Havoc and 15" Q with BP option (both have embedded tinsels) Yummy pics: Here are TermLab results... Outlaw style (at the kick, both windows open) Q: Havoc: Legal (sealed up at the dash) Q: Havoc: Listening experience: To tell you the truth, unless you are a freaking machine, I doubt you would be able to tell the difference between these two drivers under the exact same circumstances. Now everything I am saying is dealing wit…

I know the routine in making a sealed enclosure but have a few questions before I begin.... This is the first one I am making for my 15" Q and I am getting 3/4 mdf and using 1.5" on the front where the sub is mounted. I was planning on using liquid nails to glue the boards together and then screw them- should I then caulk around the inside after that? Also when doubling up the front baffle, should I just glue and screw two pieces of 3/4 mdf together and then attach to the rest of the box and cut my sub hole in both? Any other tips, or things I forgot before I start building? Thanks guys for the help!

So my q12 arrived on Wednesday to my work (where I have all shipments sent) but I was out sick for two days and I come into work this morning to find the box with a big hole in one side and looking very rough. https://plus.google.com/photos/116140861359253571917/albums/5871144803493812177 The magnet has damage all the way around the bottom edge, cracks and pieces chipped off. I have not attempted to hook it up yet and my question is should I even bother...

I'm getting absolutly no sound out of my sub it was working fine for about 10 minutes earlier and than i unhooked it so I could set the gain correctly with a dmm and after I hooked it back up I got nothing from the sub The first time I hooked it up at had it at 1/4 gain up so I'm sure it was not clipping and I only played it on low volumes, I also didnt smell any burning So could could sub be blown? Dvc 2 ohm wires parallel to 1 ohm off kx1200

Well, Im planning on buying my fi btl n2 18 aroudn december, near christmas! I have an 03 nissan xterra, so im sure there is enough room for a box in there, but the problem is, i barely know anything about sound systems and their setup/ configurations. If anyone could please explain what i would need, i would appreciate it. Im getting a new double din headunit, 2 door speakers w/ tweeters, (Which i will wire to the headunit) I plan on getting the n2 18 What amp, would be best to run this at its best performance daily? I won't be going to competitions or anything. If you can please let me know a couple good options that arent super expensive, i am not on an unlimited budg…

Look at title. As an example, a 15" Fi SSD both D1 and D2 have the same specs except for a 40% higher BL on the D2, can someone please explain what is happening that makes this configuration have that much more motor force?

I have a 98 reg cab s10, i want to do either 2 10'' Fi SSD subs. I would like to know how many i could do and rather do it sealed or ported. Any help would be nice thinks

I have two BL tens and I was looking to recone them but I can't figure out if it has a flatwind coil. If it doesn't can I upgrade to it without it being a problem? How can I tell if it has one or not cuz I need it but idk if it'll work with it

n00b to the forum that is , did this one for a local guy. I'll let the pictures do the talking. It was a little dirty sorry, I had to snap pictures off quick and vaccumed when the guy picked it up. Comments welcome, I've got a few other BTL enclosures I've done I'll toss them up as well otherwise check out my photobucket page HERE

i have a guy that wants me to do a wall install in a 2004 sunfirefor 2 btl 15's or 18's. im going to have the wall on the smaller side so it can take a little more power but do you guys think 2 btl's can take a xx-maxximus (last years) for everyday use??? or would he be better off with 2 xxv-Colossus (new ones)??

I am truly worried about this since I am eager to get a X10 or X12 and it has to deal with power issues. I have an Arc Audio XXD 2080 and it des 240 x 1 @ 4 ohms when bridged. I truly have been wanting to get a Fi Audio sub since three years ago but would like to know would the amp and the X10 or X12 would work together hand in hand or would it be a total flop?

Hey I have a 12" fi bl and I need to recone it I have it all striped down and the basket I sanded all that crap off but I need some advice on how to recone the sub and what I should do thanks for your help

Already have a ported box for the sis as I built it last week with the purchase of these subs in mind, but just read the pinned thread about the Qs. I listen to everything from avenged sevenfold to maroon 5 to jack Johnson to lil Wayne and kirko bangz. So I really am Looking for a setup that "does it all" and sounds good while doing it. A lot of music other than rap spuds muddy and sloppy on my current RE SeX 12s (prefab and custom enclosures) and just haven't been happy with the sound. Everything kind of runs together. With that being said, how will I like these subs? Current box is at 33 hz with approx 1.9 cubes per sub in the trunk; subs up, port facing forward on the …

hey guys, im gettin either 1 or 2 amps, here are my options, 1 of these bridged http://www.sonicelectronix.com/item_12212_...+BXi+2608D.html or 2 of these http://www.sonicelectronix.com/item_12210_...+BXi+1208D.html these are mono d class amps, now the bridging of the single amp is my concern, i ordered dual 1 of the BLs, would this diagram work? the subs are 1 ohm correct? so would this diagram still be somewhat valid? and if this does work, how would i design the box, because currently im planning to separate the chambers, unless one of you can direct me in the right way or i can jsut get the 2 smaller amps

I am running an AQ-1200D @ .7 ohms to a 15 BL and my friend installed it yesterday and set the gain on the amp a little less than half way and when i turn the bass knob about 3/4 up and turn the volume up to like 25 out of 35 the clipping indicator on the bass knob illuminates on and off with the bass hits on some notes. its aggravating the shit out of me because I just spent alot of money and I dont want my shit to fuck up. He told me the amp could be too small for the sub or the HU is sending out bad waves to the amp. It sounds amazing, dont get me wrong. I just wanted some advice on how to get the clipping to stop. I have a Kenwood Excelon KDC-X792 head unit and it has…

I'm gonna be putting together a daily driver system soon, and want something that pounds, has control, and sounds bad ass doing it.. I have a 2007 Trailblazer SS.... I listen to a lot of death metal, heavy metal, some alternative, some rap, and techno/electronic type music as well.. I've been kicking around the idea of three 12" Image Dynamics IDQ's, or three 12" Alpine Type R's (i know, not the same league), or even three JL 12w6v2's.... I looked at the Fi Q's, and they're nice, but a little more than I wish to spend per sub. The SSD's are a much better option. I put them in WinISD, and much to my suprise, the response is pretty much spot on with the 12w6v2.. So now,…

Hello everyone, I'm still trying to decide whether to buy one or two FI 15 BTLs. I will be buying each sub with: dual 2 Ohm, cooling package, HiXmCoil, I heat ring, and will be set for daily. For each sub, I was planning on either running a Hifonics BRZ3000.1D Pro with 3,000 watts RMS @ 1 Ohm, or a Memphis MC1.4000 Mojo which has 4,000 watts RMS @ 1 Ohm. Will the FI BTL 15 be able to handle 4,000 watts? or will the 3,000 watt amp be a better choice? Money is not an issue, and I'm going to do the Big 3 under the hood. I am also looking for the dimensions of a box for either the one or two 15s. The truck is a 2009 Chevy Silverado 1500 extended cab. I'm going to remove the…

Hello , Fi community I got my fi Q 18inch a month ago. I had some time to play with it.... hooked on a bxi2006d @1ohm Right now, it's in a 6.5 net enclosure tuned to 30hz with three 4x15 inch aeros. It hit the 35-40hz freq nicely, but i'm sure i can get more out of it. This summer, i'll be might be working on a way to use my wheel pit and get another 2ft/cu maybe. How will the increase enclosure volume help the Q, i mean in loudness and sq. I'm thinking i might get more prononced 30-40hz range, is that accurated? how much louder? is it worth the trouble fiberglassing the wheel pit??? Also, the 55-80hz range ain't loud at all, is it normal? i mean my old alpine type r we…

As of right now, I have 2 800 watt sony amps. Its about 350 RMS at 2 ohms, and is unstable at 1 ohm. My link I have a BL 15, and I'm wondering if this severe underpowering of the sub is dangerous. I don't have the money right now to upgrade on an amp. Also, is it possible to use both the 800 watt amps to power the one 15?

I have been looking alot into the FI Subs and finally going to decide to buy my first FI Sub. I decided to go with the SP4 15. My first question is I need help with ideas/suggestions of my box. Now here's what I'm dealing with: 04 Cavalier Trunk Build sealed w/ sub and port forward. 2 XS D3100 in rear Taramps HD 6500 (Will keep gain down, want to do roughly 4k Watts to sub or suggestion?) Stock Alt (Don't plan to upgrade) Daily Driver, not SPL or competeting, just Pleasure to be LOUD I play All types of music from Decaf Slowed to Christian to Rock. I want to play to the mid 20s and up to the mid 50s decent, but of course tuning area gets best, but still some output 4…

I was wondering if anyone would have any insight on my possible set up plans with my enclosure and sub and amp. First off my vehicle is a 1995 3000gt. I want to go with a single sub because it will be easier and far cheaper to set up. So would a 15 fit or would only a 12 fit? I was thinking either one of those BLs with all the options on a decent 1000-1500 watt amp would probably be ideal? Also are the speaker wire kits on ebay that are 2 gauge ideal? They cost like $40-$70 on there. If anyone has any suggestions or recommendations, I would greatly appreciate it.
