Fi Technical

Im driving a Dodge dakota extended cab and im going to be running 2 12" fi q's. I was wondering if it would be better to face the subs towards the front of the truck firing at the back of the seats, or firing towards the ceiling of the truck. Thanks in advance for any help!

So I am about ready to start this new setup. I ended up thinking that I would like to go with two flared ports with a 15" sub. Is it okay to put two flared ports in an enclosure with a single 15? I wanted to do this, sadly, for the looks so I can keep the sub in the middle of the enclosure so things stay symmetric. How do I go about this. Do I follow the same rough 12 to 16 inches of port area per cu ft of volume or do i now divide that in half since I am running two ports. Any help would be great as I dont want to screw this up. THanks.

i am toying with the idea of either a ported 10Q or a sealed 12Q. overall i want SQ, but want it to get loud. i listen to mostly rock music and really enjoy a good jamming bass line. i am a sales rep so i spend alot of time on the road and due to needing the space for samples i don't want a box much bigger than 1.5 cubes ( MAX ). my question is this- i already have the AX600DE-- is it enough to drive a 12Q sealed? i know that at 1 ohm it will drive 600W ( on paper ). the amp is extremely efficient, but will it really drive either Q? this is more of a question for Scott or someone with experience with Fi. i am not a newbie by any means- i am just looking for s…

I just read about this sub at audiojunkies. I've got a pair of AA Atlases running free air in my little creampuff, a 94 Olds Cutlass Cierra. I'm thinking of replacing them with these. Any thoughts? I'm running 150w to each of the Atlases, I'll be doing the same to these. http://www.audiojunkies.com/blog/866#continued Thanks

Anyone or ficaraudio, could sketch me a rough design for a single 15" Fi Q w/out bp power, d2 off a 1200watt @ 1ohm Vented enclosure Here is what i got to play with, for space *truck* 35" Width 20" Height 17" Depth Open to whatever tune, i want it to be low/loud but sounds good at the same time. Listen to rap/reggae mostly. Gonna use .75" MDF Thanks in advance! I wanna get started building my enclosure. Currently using reaudio box design software on their site...

I recently purchased one SSD in my old box and i absolutely love it. I will be ordering a second sub in a month and need to build a box for it. I am trying to figure out the dimensions for 2 12's around 4 cubes tuned to 32 hz. I am not sure how to create a box that fits these specs. My dad and i built a box for a w6 but all the dimensions were given so it was very simple. Any past build specs would be very appreciated.

I am planning on buying a BL 12" sub with all the trimmings for xmas... my mom recently bought me a BXI1606D Hifonics amp.... will this be too much power for this sub? i really hope not! =( any input would really help thanks in advance!!

Hey, I sent in my sub over a month ago. I tried getting ahold of Fi to let them know I never included an email or phone in the package because I forgot. What's going on with my sub? I should have it back by now? TIA

Hello, I plan to build a box for my Q18's (bp option). The box will be 12ft^3 tuned to 28hz w/4 4" aero ports eash measuring 11.5" long. Each 18 will be receiving 1600w. Please tell me if my specs are ok or not. Thank you, Larry

hey can i get a price for two 18 recone and basket for re sx shipped to 38112

hi, im new to the forum and been looking through countless threads but cant come up with the best set up for myself. i would really appreciate everyone's help! i already got a system in my car but im not happy with the bass output (plus the subs are overpowered and keep going out). i mostly listen to rap/hip hop and want to be as loud as possible. currently, im running 2 boston acoustic g5 12s and 2 12" radiators off of a mtx 1501d. the enclosure is a custom install in my spare tire well which gives the 2 12s 1cf each, the radiators are separate. im thinking about replacing the 2 12s and the radiators with just 2 Q series 12s and i see that 1cf is enough but 1.3…

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

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…

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.

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

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.

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 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

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

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!

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 have 2 15s btl. 1 is dual 1 ohm, measured 1.5ohm on each coil.(working) both 2 magnet motor. 2nd is d2 , measured 2.5 ohm. (blown) d1 sub, the pole is black color , i think that means its universal. d2 sub blown, doesnt have black colored pole. Question is can i recone d2 with 1 ohm recone kit to match my other btl, and will they have same specs? plz help me out.

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 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 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.
