Fi Technical

how would someone apply to work at the FI build house? just curious. going to college for machining and i really want to stick with car audio industry as a machinist.

For my Alero trunk I'm eventually going to buy a BTL 18 D2 with daily/all options. This is the cheapest & loudest daily setup I can think of and I've drawn up a shizload of boxes. I want lots of bass but don't want to shell out for a huge amp, alt, and batts. Power will be maximum 2000-2200 watts @ 1ohm unless I can borrow a huge amp for burps if having 1 fully charged battery will git-r-done. I will buy 1 battery and upgrade the alt if I have to but nothing crazy.

How do these box plans look. I plan on using them for my 15 inch SSD. It is going in a trunk of a 94 Honda Accord http://flickr.com/photos/8063442@N08/sets/72157605256765339/

I was wondering if 140in of port is to small for 2 of the Bl 18's? When I build my box the port would be 20h x 7w x 12d that would be 32hz. The box would be 40h x53w x14d. Should they be tuned lower or higher? Thanx Jason

12" ssd bp and flatwind options ordered it yesterday now i need help on dimensions for a sealed box any help or suggestions?

I have 2 mono amplifiers of the same kind and I have a dual 2 ohm sub. Is it possible to put each voice coil to each amp without hurting sub?

So...I installed my new sax-125.2 amp for my components...got it hooked up...turn on the truck....HORRIBLE alternator whine.... so i grounded the RCA cables on the HU and bam its fixed(pioneer HU btw)... so then i went ahead and tested my components. well i turned up the volume and BAM my Fi Q just died . i tested each connection with a DMM until i took out the sub and well i lost a coil...i have no clue what happened...the sub is going on 3 years old now and i know how that sub acts by heart. i know i wasnt pushing it too hard and i was at 2 ohm on my saz-1500d in a 2.4 cu ft sealed box before sub displacement. also it was on for maybe 20 seconds before it died so i kno…

i just ordered 2 12" Fi Q's and i've seen specs on how many cubic ft to make the enclosure and stuff like that but i want to know the specs on a ported enclosure for TWO 12" fi Q's!!! i just want the best for my twins and whats up with all this tuning to (x) amount of hertz and s*** like that?? how the f*** do u tune a subwoofer??????? well all i know is that i want my twins to play as hard as possible with the best sound quality and for people to be like WTF DO U HAVE IN UR FU**ing TRUNK MAN!!!??? lol feel me? so i just need 3 questions answered: specs on a ported box for TWO 12's.....whats the ideal hertz to tune the subs to (and how to do that).....and please list the…

Hey everybody i have a quick question, im thinking about buying a 15" Bl but i heard that if I just listen to rap and hip hop that the 15"Q would be the best is this true and also its gonna be running of a RF P1000 1bd do i need the bp power if i get the Q

I just bought a 12" Brahma MKII, its working but has had the tinsels resoldered after they broke. I was going to attempt to repair the tinsel leads and run with it like that, but, the guy I bought it from originaly said it was a 10" , now he says its a 12" , so I want to go ahead and recone it down to a 10". So, I want to go ahead and place an order for a 10" recone kit with 10" basket and gasket shipped to 26851. Just wanted to post this here before I send any emails.

Well my 1 18in fi bl mag cracked. Dont ask me how lets just say that i am very sad that this happen. And another bad thing that happen is one of the voice coils went bad in it to. I took one of the subs out of the box cuz i heard alot of buzzing. Then saw that the top magnet of the motor was split in half. I dont know why this would happen but it went from me bumpin super hard to only bumping a little with one sub. So if anyone has a BL motor please let me know or give me some info on how i can get it replaced thanks.

I have a 15" BTL fully loaded with 4000 wrms in the back of my jeep cherokee it is in a audio enhancers box right now. It is loud but I believe it could be way louder with the right box can anyone hook me up with some plans? Thanks in advance.

INFORMATION: I own a 2002 pt cruiser. I am going to soon be buying a Fi Q18 and a AQ1200D for my car. I have calculated maximum external volume that the enclosure can be and it is around 8ft^3. I will upload some pictures tomorrow but its dark outside so I can't go take any pics. Two Options: 1. Sealed. Would allow me to downsize the box a bit to around 6ft^3 and give the sub some more breathing room. 2. Ported. I would keep the volume at the max and port it to 28hz like recommended. My only concern is that the space between the Q18 and the rear hatch is 4 inches. I know this will affect the sound but I don't think it will be too big of a problem. So what shoul…

I'm looking to recone two LA storm X1 10's. I want to use 12's instead. So what I need is two 12in baskets, and two recone assemblies that fit in the 3HP gap. I haven't been able to find out anything about the gap, other than its a 3in coil. But I saw at CA that you guys reconed a 3HP neo. What series coil fits? Thats the question. As it is right now, I have a Fosgate 1000D on each sub, so dual 1.4 or 2ohm coils would be what I want. I can say that they will be going in a 5cu ported box. (thats the largest I can fit in my car.) And I'll be using them for daily.

Hey, i recently built a box for my 2 Fi X 12's, it is a ported wedge box 4.37 cuft after port and sub displacements. I have a 4 inch ,"precision port", flare port and is 6 inches deep. The problem is that the sub closer to the port moves more and im thinking that i could get more out of the subs if they both had the same movement. A little confused.. i was told that it would be louder if i would have divided the box and but two separate ports, one on each side rather than one on the passenger side. By the way i have them on a Autotek MM1000.1D

Or should I say my son wants loud. I've e-mailed Scott a couple of times, but I know how busy he gets. I thought I'd try here. What I'm looking for is the loudest possiblw set up that I can get with an honest 1400 watts @1 ohm available. I can build a box any size I need to, so that's not an issue. It's going in a mini-van so I've got plenty of room. He's trying to do better than his current setup of 2 AA Arsenal 12's in a ported box (tuned around 32-35Hz). My initial thoughts were 2 SSD18's w/dual 2 Ohm vc's in a ported box, but I'm looking for advice from someone from Fi. Once the drivers are chosen, I'll need help with box dimensions. TIA, Carl.

Greetings, and thank you in advance for considering my inquiries. : ) After becoming privy to the specs and recommendations for the 15" BLs, Qs, and SSDs, I have hit a wall in my plans for purchase. It appears ported enclosures are exclusively recommended for the BLs and SSDs of this driver size. However, the problem is the recommended tuning of which is higher than my target low frequency response of 20 hertz. My questions are: 1). Are these recommended tuning figures aimed at SPL applications? I'm far more concerned with brilliantly effective low range response than mid- bass volume. 2). Can they be tuned to 20 hertz and still be effective drivers? 3). If not, would a …

Like the title says...I'm a noob, I just like alot of bass. so i just ordered a fully loaded BTL and was wondering if someone could help me get some dimensions for a box. The box can be about 35 long and 20 wide and however tall. I obviously want it to be ported. Also, I was checking out the RE calculator..Is that accurate at all? If someone has some box dimensions for a box they built themselves for their BTL I would love to see them. Thank you

My enclosure specs are 36 wide 18 tall and 30 deep. According to the12volt.com this should be a lil over 9ft³. I want a 33 Hz tuned port I'm still undicided between 4 by 16.5inch port with a 11 inch length or 5 by 16.5 inch with 14 inch length. I'm more in question about the lengths. Are they accurate?

Can somebody post them up? Trying to see if they'll work on my rear deck using the 19.1 cubic foot Cadillac Deville trunk...

ideally, what would be a good power range for the ib3 12 inch sub?

I'm going back & forth between using 2 15" IB3's & 1 18" IB3, but am a little concerned about their output between 50-80hz. I'm going to use 8" pro audio midbass in my doors, but from what I've read they shouldn't be crossed lower than 80hz. Does anyone have any input they can give me on the IB3 line playing these higher frequencies?

I know that you don't sell ib3 8" subs . But could you and at what cost ? Looking for one for the rear deck on my Lexus .

im looking at using the ib3, and was wondering if there are any technicalities that i would need to take into consideration before doing it in my car. i would place the baffle behind my rear seat, and seal everything off w/ fiberglass where it goes under the rear deck and between the wheel wells/strut towers. anything else to take into consideration?
