Fi Technical

just crusin didnt even make it off my street sub up like half way.. sub cuts out, amps not in protect, no sound whatsoever out of the sub... pull out the DMM.. 2.1 ohms resistance at the wires out the sub (my dual 1 BTL in series) ok.. sub is not blown? set to voltage.. check the outputs on the amp got fluctuation in voltage with music on, unplug the RCAs voltlage stops fluctuating.. so i figure I'm getting signal from the amp, from the headunit, to the sub... where the hell is my problem I'm stumped.. Dual 1 ohm 18" BTL in 6.7 cubes@31hz in series to 2ohms Hifonics XX-Cyclops wired to 2 ohms ~3KW RMS been running it this way for about 2 years maybe longer.. didnt c…

Whats up, Can anyone give me advice on how many cubes my sealed enclosure should be and what it should it be tuned to? I will give it hopefully 1300 rms with a hif1606d. I listen to about 80 % rock/classic rock/metal/blues/acoustic live chit and about 20% rap but I will probably listen to more rap since I will have a sub. The sub needs to play 80hz and below. My goal is pure sq not spl Thanks for any input Captain SSD(lol and its gonna be a q)

all my life i have been a sealed guy, i just love the sound of a sealed setup and how low and deep they can play, so i got talked into going ported for my next system..im going with 3 18'' fi Q series, fi suggest 6-10 cu ft per sub, im thinking of going in the middle with 8 per sub, im also going to throw 800 watts at each one, what do you guys think about this? i will be using this for daily driver and i listen to both rap and rock music..so im hoping the subs can keep up with the fast beats..also 28hz sound good to you guys?

So as of right now i have a Q 15 powered by a BXI 1606 running at 1 ohm so the sub is dual 2. My next goal is to get another Q 15, but I really want to get a RF T3000 but they would have to run at 2 ohm and be dual 1's right? So i would have to recone my current one or 2 (if everything goes right) to run at 2 ohms. But then agan if i end up w/ 2 dual 2 Q's i could just get 2 RF T1000's I just need some advice -send in my current Q for a swap and get both dual 1 so i could run the T3000 -keep my current Q a dual 2 and run each off T1000's How much actual power do the T1000's put out? Do these hold up to the other T line? I know a T3000 would be very generous for 2 Q's but…

the thread is much more developed here http://www.caraudio.com/forum/showthread.php?t=265327 but i will post here anyways, since i would like to get an idea of what some new tinsel will cost me so i can try to do a repair. so my btl stopped working today when i was listening to it on volume 35/70 on the highway. i thought maybe my wires came loose. get home, pull out the woofer and this is what i see at first glance i thought i clipped it. i take a look at the coil...its fine. never smelled anything either and everything is in the same condition as when i recieved the sub. and the other tinsels dont look burned to me at all. i am the third owner of the sub. it does loo…

Im gonna get 2 12in BTLs and I was wondering if they could handle 3,000RMS or higher and not have to worry about it, and the sub would be a daily sub but fully loaded otherwise.

i want to build a new enlosure for my 18 btl. ive never done any bandpass box before and now id like to try it. do you have any suggestions or a website were i can find a good instruction how to build a 6th order bandpass (calculator)? i have a suv and ~10 cft of space.

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 just got my BL in the mail from Joseh K. and USPS has fucked my basket UPPPP Could this be fixed my some very careful welding? I mean what else is there to do with it.....

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

Hey I going to be getting 2 Fi BTLs fully loaded with the daily instead of SPL option, should I get the Rockford Fosgate 4000-1BD or Sundown 3500D?

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?

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…

I'm curious if you guys could build one for that sub? 4" coil, 10" spider landing Must use a spider spacer too. Which I have, it uses an inverted neo motor OD is close to 4-3/16" maybe 4-5/32. My calipars don't go past 4" lol thank you

you've got mail

Ordered a fi btl 15" fully loaded have a hifonics brz2400.1d I know not the greatest of amps but too much or too little for that sub I know everyone saying the can take more than 2000rms but how much?

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

Hate to be that noobie, but I've scoured the web and everything I can find for the options refers to the old options and none of the newer ones that are selectable. Could someone help a noob out here? haha.

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…

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

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

okay I'm really confused right now. I have a feeling it's the cold messing with stuff but I'll seek some guidance anyways. So one day I warmed my sub up good and set the input lvl on my amp so it was all good no bottoming out or clipping or anything. I even set it with the volume a bit higher than I normally listen just to be safe. So then it gets really cold so I turn the sub woofer lvl down on my H/u. I've had it down for a bit now and as I warm it up I'll gradually turn that up along with the bass control knob. The other day I'm on my way to work (~15 min drive) and listening to my music after I had already been warming it up for a bit too. When I'm nearing work i cont…

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,…

Is it safe to run a single fully loaded 18'' BL on a Rockford T2000 @ 1ohm?

I decided to wire my entire system myself. My question is wiring the dual 1 ohm 15 " ssd to the MTX X1000D mono bloc class d amp. Im okay with everything else. Just need to know how to wire the subwoofer to the amp to 2ohms..The amp is rated 1000W rms at 2ohm. Thanks in advance.
