Fi Technical

I just received my ssd 18"s and they look sweet.....thankyou. Well my question is......I ordered dual 1ohm coils so I could wire each of them up for a 2ohm load....any idea how to do that??? I am using them for hometheater and hooking them up to a behringer ep2500----its 2 channels @ 2ohm per channel @ 1200w. thanks email is [email protected] I think its supposed to be....... terminal 1....positive to amp--- terminal 2....neg to amp--- jumper between left over neg and pos........ Is this correct???? thanks

I just picked up a 15" SSD and everything else for my system other than the box itself. I have got no idea on the tuning frequencies and port sizes. Can someone help me out. Ive got about 30W X 18H X 116L room in the back of my truck. Would a prefab box sound okay? Thanks in advance

Ive got a Kicker KX600.1 that I'd like to pair with a 10" SSD to avoid purchasing another amp. The amp specs are RMS Power at 2 Ohms 600 W x 1 RMS Power at 4 Ohms 300 W x 1 Opinions on this vs getting something for the 1000rms rating of the 10" SSD

my max dimensions are W:40: H: 14 or so D: 20 freq wanted. : 32. Daily driver. could someone help me our, or is my height screwing me over?

I have 2 btl 18s, 220 amp alt, kicker 1/0 wire 2 aq 3500's (should be here monday). I am currently building my box and have NEVER ran with this much power before so I wanted to make my box a little smaller than my old one I am looking at about 11 cubes net tuned to 36 hz 152 square inch port. I just would like some input if I should go bigger or smaller on the box please input asap...oh ya by the way the subs are dual 2 ohm fully loaded ( I have pics of my equip if anyone needs proof lol)

Guys Prob havent post for over a year now, thats because I have kept all my things in the closet and lost touch about car audio while playing mafia wars LOL. My question are: i. How long does a sub magnet stays magnetize? In my place 33c-35c is considered a normal sunny day. ii. Does heat from the sun + heat from playing music will effect the magnet strength? iii. Does keeping the sub in the closet (its bare and I didnt put it in the box) will have other effects like rust, deterioration of rubber, spider getting weaker etc? Btw I own 2 15Q's which I bought back in 2007

I dont know if I should go sealed or ported? I listend to all types of music but mostly dance that has some hard hitting and low bass. I wouldnt like to sacrafice my whole trunk if possible and this will be pushed by a sundown 1000d

K, now I know what you are all going to say, BUT before you do please give this a read. I have a pair of BTL 15's (D2) that I am planning on running with a pair of SAZ-3000D's I know the box recommendation is 3-5ft^3, with the power, would I be better off staying on the smaller side? I know when you start going bigger the mechanical ability sub goes down, but the trade off is more forcefull bottom end (which I would like to have). I'm planning to have between 6-8ft^3 net enclosure tuned fairly low around 30-32hz Just curious as to what you guys think about my ideas

What up everyone! Newbie to this forum!!! Just want some opinions on going sealed with my Q18s. I read a couple of threads on here were some folks are running their Qs in sealed enclosures and they seem to like it. Currently mine are in a 12.3cu enclosure tuned to 30hz and I pulled a 146 @ 39hz with it. Here a link to my current build http://www.*****.com/board/ind...?showtopic=3714 Vids http://www.*****.com/board/ind...?showtopic=8473 I've got good sq now but want better and I think going with a big sealed enclosure would do it. Want you guy's opinions! Thanks!

does my 1997 4 door bravada (exact same as 4 door blazer) have enough space for 2 18" BTLs? or would i be better off going with 1 18"? either route i go i will have 2kw rms to EACH woofer... my max dimensions are 48w 30d and 20h.. going ported if it is only enough space for 1.. does anyone think 2 12" BTLs will be louder than 1 18"??? sorry for all the questions.. they may seem pretty dumb but i want to be sure about what im doing BTW I'm looking for a pretty good SPL but i want to retain SQ for daily listening right now i am running 2 MTX T9512-44s on 2.4kw @1ohm, in 4.5 cubes each ported tuned to 35hz, i would like to have about the same SQ as these if any one has h…

with a box at 27x21x27 what size port would i need to run a 18"btl at 2000 watts? this is just the available area for the box. with displacement it puts the box at 7.13ft^3. and i am using 3/4 mdf. or would it be better to run both btl's in the same enclosure and port it. if so the box would change to 27x42x27. what port length would be needed to run it at 32hz?

My fully loaded BL 15" came in today so started to design my box. I want to use an 8" aeroport and wasn't sure if it has enough port area. Box is 5.5 ft.3, 8"x17.5" flared aero tuned to 33hz and going to be powered by a DD M3a at .5ohm. Will the 8" aero suffice or will it choke the sub?

Im looking at buying a Fi BL 15, im going to run it off a 1700 rms amp. i dont know what opions should i get. i was looking at the 4" coil. i think that makes it 1500 watts rms i heard but im still undecided. little more opinons would be helpful.

hey nick just tryin to see if this was indeed fixable, i got it from david (basebalz13) the magnet is cracked and its seized. i got pics not sure if david showed you or not already. if you want i can upload em.

I might buy a new dust cap for my sub i mean yeah it'd look odd but yeah this one i have is horrible. How much is it to buy one and how easy is it to put on? Also is it possible to just ship my sub to FI to see if they can recone it completely? Its a 4inch coil and idk the ID of it yet. Thanks Joe

I'm going atleast a 7cuft box tuned to somewhat 30-35hzt range. I'm building my own box and the subs aren't here yet. According to UPS the subs weigh in at 54lbs each. I'm simply asking if i should double baffle the box?

sealed up at the kicks i hit a 144.8 with my single 12" BL. at the dash sealed i got a 144.3 the meter was an audio control. and i lost 1 db when i opened the window. song i used was airforces and hypnotize. they both did about the same number. Basically what i want to know is if this is a good number for a single twelve trunked car? could i get it higher by using a 50 hz test tone or somthing?

I'm too lazy to A. Look down this page a bit to see the other 8 questions asking the EXACT SAME THING. & B. Use the search function. & C. Go read the stickys at the top of the page that list recommended enclosures for all of Fi's subs. ...so I figured I'd pollute the board some more with my "problem" that really isn't a problem, and doesn't need anymore discussion. Thank you.

Details - Fi Q12 Ported - Down Firing - 2.0 cu.ft. Net Volume - Port @ 33hz, Amp Tray Additional Detail - Due to the spec's required relative to the size need customer is willing to raise the rear seat 1.5" and the enclosure protrudes past the front of the seat edge 2". Again, Thank you Scott for the measurements for the Q12. Best Regards, Phil Woodlawn Cabinetry

Hello, i want to build a box for (2) FI Q 15s, here is the size of the area i have too work with WIDTH = 32 INCHES HEIGHT = 18 INCHES DEPTH = 29 INCHES I will be able to add height to the box if I shorten the depth for a sealed box i can use the cutout sheet that FI recommended at 2.5 c.f., i'll just build two seperate boxes then just bolt them together. now for a ported box i have no idea what volume or what to tune it to??? i listen to metal, rock, country, blues,everything inbetween, but i don't listen to rap. FI specs for a ported box is 2.8 - 4 cu. ft. and use 12-16 sq. inches of vent area per cubic ft. of volume. i would like a box that would not be too boomy, i lik…

hello, well i decided to put my (4) Q 15in. subwoofers in the bed of my chevy s-10, standard cab, it will be a blow through, has anyone done this? where can i get some information on how to do this? where i can find the boot to put between the cab and box? well thanks for your help, Brian

A different account huh? I see your location has changed to "US", and so has your IP address as well...interesting. because h disable my account so cannot post thread that why i sign up new account old account cannot post thread and reply too they disable Yes they disabled your other account because you are being very childish and suspicious, he already told you he is not going to build you a box so try somebody else or try asking someone that lives in your area i told him just do shipping US my friend live at US lah but he wond help build box for me i have money i can pay so no problem but he said wont help what i wrong

What is the 15" bl in sd or the cone area in inches not sq inches.

Well my mojos are starting to suck...blew a coil actually. And now its time to upgrade to BTLs I'm stuck between 2 15s or 2 18s Here is the scenario: The ports will be outside the box. I am going to use these ports... Deal Breaker for 15s: the only practical option is to use 1 of those ports for 8 cubes Fi recommends 12 - 16 square inches of port per cube 8cuft x 12 = 96 8cuft x 16 = 144 So about 96-144 sq inches recommended. that port is only 70 sq in. Would that be a problem? Deal Breaker for 18s: The only problem for the 18s (using 2 of these ports) is that the box would simply be too long to conventionally mount the ports outside the box... So to still be able to …

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.
