Fi Technical

Hey guys, can someone with knowledge I don't have give me a hand PLEASE! I'll be real grateful! I bought my 2 10" FI D2 Q's for this box for my 350Z which has a advertised inside dimensions that produce .70cuft per chamber. Scott's advertised cuft spec for these subs is .20 -.60cuft. So I'm about .10cuft over. First a couple of questions. (getting old sucks....memory shot! LOL!) #1. I think Scott said he wanted the .20 - .60cuft space for the box PRE sub installation???? So in other words don't use the sub displacement itself in the final cuft #. The box without the sub should be .20 -.60cuft. Does that sound right? #2. Obvisously I want the BEST possible performanc…

whatup folks. i am going to run a second battery in my car i know that 0gauge is the best but can i get away with 2gauge? i already have the whole car wired with phoenix gold pos and neg 2 gauge. would hate to have to buy all new wire if i dont have too. i am only running us amps 400, and esxq404 four channel amp with soon to be ssd 12's with copper coils. im thinking this would be okay but im not sure never ran two batteries before. sorry for all these questions but i m just now realizing that as loud as my systems have been i could get more out of them since ive found forums like this to help. thanks for any help you guys can give.

Mainly for the bigger heavier 18 inchers but not excluding other sizes.I'm curious to see what you use.Bolts,screws,clamps etc.Do you switch from screws to bolts at certain weights and so on.

i was just thinking(usually dangerous) i have an amp that is1200 @2ohms mono, 600per channel@1ohm. presently i have dvc4 woofers if i hook them up the regular way i get 4ohm or 1ohm mono. i have been reading that some people hook an amp to both voice coils so each amp i guess would see 4 ohms off each coil, right? now heres the crazy part; shouldnt i be able to take the + - off one coil on one speaker then the + - off the other put them together on one channel and get 1 ohm? then do the same for the other coils and get the same for the other channel, now all four coils are running off two channels thus giving the amp its 1ohm per channel? . is this possible or am i thin…

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.

ok so my brother wants to get a fully loaded 18" BL for his 00' blazer. hes got a stock alternator i think 105 amps, and hes thinking of getting a hc1800 battery in the back with a hifonics xxv or xx thor amp. will his electrical be okay for this?

Ok, I Have the Pioneer AVH-P5000 HU, an AQ-2200 amp, and 2 Fi Q 15s that are in a 5.5 cu.ft ported enclosure after all displacement that is tuned to 35 Hz. The HU has a RAC output of 4 Volts so i match that voltage as close as possible (3.9V). I tuned my enclosure to 35Hz so my Subsonic level is set to 30Hz. I know that the gain is the most important setting to any amp, followed by the Subsonic filter if you have a ported enclosure. Now am trying to find out how to set my Bass Boost and Low Pass Filter. I looked through the forum found info on the Gain and Subsonic filter but couldnt find anything on the BB or LPF. Are they just set by ear or do they have parameters. Can …

Ok so My FI BL 12" just arrived, i had a 18" previous in my Ford explorer. Now since I have a 240sx i need something smaller. I have my amp (saz-1500D) all set-up and ready to go. I forgot i need to reset my gains because when I tested the sub I could hear it clipping, and for some reason my gain (min/max) control knob mounted at the front of my car did not change the output of the sub. I lost the original cord but i read a phone cord could work so i tried and the blue led works at least. I digress to my problem which is that i forgot how to set my gain. I remember sticking in a 60hz cd at 3/4 full volume and reading the voltage from the amp but i forget the calculation. …

hey guys heres the deal, i finally got my ported box completed and installed the D2 15" BL, hooked up the amp (aq1200d) to 1 ohm, saw that my fuse is blown so i had to use my friends to see if everything was working.. the amp was showing power, and hooked up a capacitor just to see and it was getting the proper volts, but NO response from the sub, no movement at all. We were soo confussed, everything looked properly installed. just wondering if anyone has any ideas! Please help, i appreciate any given. I miss the bass also how do i properly tune my amp, and where do i put the knob angled at on the subsonic, i need it set about 30 hz which is 2 under the box tuning, but t…

I have a box design in mind (i just need a car to see if it will fit or not) which has two either 15 or 18 inch (depending on available room) BTL's or BL's. I am not sure though if these subs are designed to be able to share a box together. I was originally going to run just a single BTL 18" in a 7 or 7.5 cu/ft box, but i wanted a more good looking design, so, as an example, are you able to run two BTL's in a box of volume 14-16 cu/ft? Or the equivalent volume of the BL's? I'll try to draw what i want it to look like on a CAD program or something, but i would like to know if it possible first before i start buying materials. Thanks

I was going to oreder a 12' fi sticker for my truck but the shipping is 12.00!!! Why and how is the shipping that much??? Its a 0.76 lb sticker that costs 4 dollars. But 12 to ship somethings not adding up here.

hey all im really sold on getting a bl 15 for my car. i was just wondering how much it will cost to get it shipped to montreal since it states on the fi site that shipping only free in the states. im also wondering if the flatwind coil is good to get if i plan to use the sub daily (will it give much better sound).

I was just wondering if anyone knew of any good car audio shops in Ohio (Columbus would be best) that have worked with Fi audio before and could do a custom wall for 2 12" BTLs and probably 2 TD20001 r/f amps. I like competing in meca's car shows (SPL) and i don't think i should do the box like originally was going to. Thanks

I have been searching all over the internet to find out about qts (never even heard of it before i was looking into Q's this isn't my first system, i just never accounted for it before. it looks to me like it is highly dependant on what you are doing fi q 15's have the cooling and spider upgrade options, that is it i am going for sound quality with this build, dual fi Q 15 in a sealed enclosure measuring ~ 2.3 ft^3 per sub (after displacement and bracing of course) each sub will have it's own rockford fosgate t-1500-1bd giving them ~1350watts @ 2 ohms (already had one and just bought a second off a friend, who said headroom was a bad thing) they will be in the back…

Ok, so I already have a Fi Q that I have been bumpin for about 4 months now. I am planning on getting a second Q after X-mas. Should I recon my broken in one before throwing it in a box with a new woofer? Also, what would be the total price for a recon kit with is being sent to 95677. The sub is a Q 18

Hey guys, Mr. Noob with here with another question again.......I am putting in binding posts to replace the terminal cups in my sub box cuz all my wiring is 8 gauge and the cups do not accomadate 8g wire. Plus I always go "OVERKILL" for peace of mind. When talking to Mike of Zenclosures(guy that made my box and he's GREAT guy like Scott is by the way), he said I could just use silicone to seal the new posts. I've seen people here talk about caulking so which is better? Or is silicone adequate? Enquiring minds want to know????????????????

I have a silverado extended cab and was wondering how you guys think this would sound with 2 ssd 10" powered by 900 watts rms @ 2 ohms http://subthump.com/Chevrolet-GMC-Sub-Boxes/Silverado-Sierra-Extended-Cab/99-06-GM-Extended-Cab-Dual-10-Downfire-With-Amp-Space.html The volume is more than what is recommended for the subs, would that be bad?

What is the difference between Running my SSD 900RMS@2ohms or Running my SSD 900RMS@1ohm. I think it has something to do with efficiency?

So, here is my problem. I am going to be running one sub and I have a slight "Monk" issue...for those of you who know that show. I feel like things have to be balanced out. So, I want to put my sub in the middle of the enclosure and would like to have two ports, one on each side. Is this clausable and how do I go about figuring out how much port area I need. The specs say 12-16 sq inches of port per cu ft of box volume. So I am planning around 40 sq inches of port area total. Would this be 20sq in per port or am I calculating this incorrectly. Any and all help would be happily listened to. Thanks

Hello, I am trying to find designs for a single FI SSD 12 inch ported subwoofer box. I want 2 cubic feet tuned @33hz. I can only find plans for 2 SSD subs in a box. Any help would be great!

The car is a 2001 chevy blazer(SUV). I dont want to take up my whole cargo space for this single subwoofer. I dont know wheather to go with sealed or ported, what would be the pros and cons. Would anyone know an estimated demension size(hight,width,dept) i would be expecting to get with either ported or sealed. THNX alot

Im planning on purchasing a single 12" SSD not sure what to get DVC1 or DVC2, i have a 08 ZX 750.1 kicker mono (2ohm stable). Now for the axcual question i listen to rap/hip hop, trance, and alternative rock and i have no clue what so ever on the enclosure that i need to use for the type of music i listen to. I have no idea on tuning ports. I would really appriciate if poeple could help me out to get what im supposed to use. Im looking to get a ported enclosure and this will be used in a Blazer(SUV). BTW how many cubic feet would be good for the sub. Im not looking into getting a humungous box in my cargo area. THNX

I'm kind of limited in space but here are the maximum external dimensions 34"W 18"D 14.5"H Sub is Fi BTL dual Mag. One out of Shawn Fleming's van from 2007 Dytna SBNs if anyone is familiar w/what he had. I only know that tit is a dual mag and will definately play music. Amp Sundown 3K Not looking for SPL nor just the LOWZ Sub up port back (I will do both in center although woofer mounted to one side makes more since to me) but hey what do I know I can't even measure CF So I guess basically can anyone figure out how much Cf my box will be minimal bracing (just 3 2x2s) 2 13"L 1 32.5"L and dimensions on a port WxH=port but how deep to adjust the tuning? Would like …

I have a 94 Ford Lightning and currently have a Alpine CDA-9883, Kicker KS components,4 gauge wiring, 12" L7 and Hifonics 1508D amp. Im wanting to get as much bass possible out of a single cab truck without cutting my truck up. So im looking into the BTL 12".Should I go fully loaded? I will be playing this sub everyday. At 1st I will have it running off my Hifonics amp putting out 1500rms at 1ohm. Do I need the dual 1 or 2 ohm to run it at 1ohm load? Then when I get some more money ill get a better amp. How much power can a fully loaded BTL 12" take daily? Im thinking about the Power Acoustik BAMF 5500 amp putting out 3200rms at 1 ohm. The biggest box I can fit in my tru…
