Fi Technical

id like to know why my 4000 watt amp wont push 1 15 Bl fully loaded without blowing both my 40 amp fuses in it.

in my f150 ext cab with a 12" ssd with flatwind and bp and hifonics bxi1206

I have a BL 15 dual 2 ohm wired to 1 ohm. How would I find the resistance? On the specs page it says it is 1.5 ohms, but since I have it wired to 1 ohm would it be different? I am kind of lost as to what my target voltage should be. Sorry I am just starting in the car audio scene so pardon my noob question

i sent you an email regarding a technical aspect of the BTL. its regarding info on if there is a way to physically measure the gap on a btl motor to identify a SPL motor from a Daily gapped motor. i talked to Nick about this issue, but after being convinced that my btl was a daily gapped motor...i now am doubting it. i took the woofer out of the box today and the sound it makes is just so mechanical metallic sounding on music. this to me would suggest a spl gapped motor. this motor originally belonged to kenny pollock and he said the SPL and daily option were not available at the time when this motor was made. however, it does have all the other options on it (fully loade…

I know that FI can recone the 3hp motors(3000's) w/ the tall top plate. Its has the 4 holes on the top plate. I know you machine adapters. My question is, instead of sending 70 lbs of motors to you to be reconed, could you just send me the recones/baskets adapters and I'll do it myself. It'll prob save a bunch of money and possible shipping damage( I don't have good luck )... Thanks, Joe. P

How would having an enclosure bigger than the recommended box volume affect my system. I am planning on ordering a 12" SSD w/ copper coil. I am trying to save money on this system which isn't something I'm used to since I usually go all out. I was thinking of buying an already made enclosure to cut down on costs. I'd like to know how this would affect the sub's performance. Here's the box I was looking at: http://sonicelectronix.com/item_7521_Sonic...Box-+1SA12.html Thanks!

I have an 18 SX that I would like to have reconed. What is the procedure to have the sub sent in and reconed? What would the estimated price and shipping to 30286 (Georgia) cost? I emailed Fi Car Audio about a month ago, but unfortunately, I never got a reply. I've sent a couple more emails here and there, but still, no luck. Anyone have any ideas of how I can get in touch with them? I would call, but I was unable to find a phone number. Many thanks, Mike

does flat wind coil and bp power add to a 12" ssd? how about bp power on a 12" Q? just thinking about future upgrades. thanks.

I just finished building my box last night.... Double baffle,Fiberglass,etc... My box after bracing and before the Port was 8.25cuft(internal)I have 119 sqin of port tuned to 30hz. After the displacement of the port I now have 5.85cuft. Now is my box 8cuft tuned to 30hz OR is it 5.85cuft tuned to 30hz??? And would that be too small for an 18?? thanks

enclosure is exactly 1.9 cubes after displacement of the BL and the port tuned to 35 power is gonna be a rockford t10001bd going for a decent daily spl oriented standard cab and thats the max box size with my knees almost int he dash(i drive like that anyway short legs lol) the website says 1.8-2.5 ported

I am looking for a recone for an SSA Icon motor and was wondering if you could do it. I am looking for max SQ as it is going to be for home use with a pair of B&W DM603 speakers. I also need a basket, I am looking for a 12" recone and basket.

Sent an email, and with all the set backs I've heard about with the email provider you use, I thought it might be easier for you and me to put up a thread about it here. It's a 15'' and I would like d2 coils. Was just wanting to know how much it would cost, and if it's possible to get the person whom I'm trading with for it, to ship directly to you, and you ship to me. Thanks, Jonathan

Anyone know how to figure out the resonant freq of the 10" BL's? I know they are supposed to be 40.3 Hz, but I had Fi tighten the suspension to handle more power on burps. How do I figure out the correct resonant freq without spending $100 on the Dayton woofer tester program? I had them built with the SPL option and the flatwind coils if that makes any difference.

what is the recommended port area for ssd's? box will be around 5 cubes tuned to around 33hz. 1 port 5" wide 20.75" long would give me 75 square inches. and 4.5" wide 17.25" long is 67.5. is one better that the other? and y? also just curious how much does a 12" SSD weigh and a 12" Q?

I am in need of two 15" recones and baskets with screws for my RE SX's at the moment, I will need two more at a later date. I need dual 1's with some slightly bigger tinsel leads, not the spl ones from the btls, if that is posible. I need the total price for all of that shipped to 47987. Thanks; Andrew

I have a bl 18 with a jl 1000/1 running it..the other day i was driving and it jus shut off, I checked to see if i could see what was causing it and the amp was still on but the sub wasn't working..a little bit later it came on and would shut off after it hit a couple times. Then it came on one day and worked flawlessly for 3 or 4 days and now its shutting off again. I think it might have something to do with the temperature because the days it worked it was 50-60 out instead of in the 40's on the days it shut off. I checked the ground and all the connections and they're fine. what do you guys think it could be? please help me out thanks

Anyone have the T/S params for a fi x 10"? Team FatStig

im doing an instll in a 88 s-10 blazer for 2 12" ssd's for everyday use tuned around 33 what type of box do you guys think will be best? i was thinking about a crx type box but what size box/port should i go with?

Could one of you check my port length for me? 4 cubes @ 32Hz with 2.75" wide x 20.5" tall port is what I'm aiming for. I used an online calculator and it said the port needed to be 29.5" long... but someone else told me it needed to be like 36.5"? Thanks a lot

Does the copper option affect (lower?) the power handling? Since the flatwind increases power handling, decreases SQ, and the copper increases SQ a bit, the copper must have some kind of trade off, which I was thinking was a loss of power handling. Just wondering, Trevor

Hey guys, I'm looking to build my own vented enclosure (my first) for a 12" BTL fully loaded. I have looked at the box builder programs, but am having trouble. Would someone please design on for me? The maximum dimensions are 15"H x 34"L x 30"D. I plan on making it double baffle, and adding a magnet holder. But I guess before finalizing a design, I was thinking that it should be tuned to 35Hz, what do you guys think? Thanks for the help in advance, Justin

jl 12 w-0 4 ohm. can this be reconed?

what size of wires do ppl use for the 12" ssd?

I am having trouble figuring out the proper dimensions and port area for 2 12inch Q's. I want to have a total of 4 cubes tuned to 32 hz. Any recommendations?

Im ordering a 15 Q soon and am going to start on my box for it. I was messing with re box calculator and having a few problems getting the right size, i have limited space in the trunk of my civic. I am going to run it ported at around 32hz and would like to get as much cubic feet as i can out of my trunk, any help would be appreciated. Box can not be wider than 34 inches, can not be taller than 16 inches, and can not be deeper than 18 inches, any help would be a appreciated. The cubic feet part is easy to me but the whole port part and how long the port should be is confusing to me. thanks Also on the re box calculator site which number do i use to figure out the 12-16 s…
