Fi Technical

I recently totaled my car, so I'm selling the system to my cousin. He has an Explorer and where they're from, loud is the only thing that matters. Anyway, he's been entering in comps with two JL 12w6 on a old punch 500(or somethin like that, not sure the model). I have two FI Q 12 with Bp power I'm selling him, along with a Rockford Fosgate T20001BD. Size is not really a problem...he has the entire back of the explorer to fill if necessary. I'm just looking for a big box or whatever will get the job done to throw up big numbers and still sound decent. He said he put up like a 141 Outlaw with the JL's. If that's right, gotta put that to shame to show everybody whats …

I have 2 loaded btl 12s that Im going to be running a T4k on. I want to use aero ports but the only way that I can get enough port area is to go a bigger than the recommended 2.5ft3. I may have to go with something like 2.7-2.9ft3.....is this ok for daily usage? Or will it hurt the woofer? I see on the Fi site that u shouldnt go any higher than 3ft3. Id be below that but they say 2.5ft3 on this site?

I have a 2001 PT Cruiser with a alpine 9887 hu: I used to have to pussy type s subs in the hatch and just didnt cut it at all. Saw the FI Q and fell in love.. So here is my questions if a get the Q 15 with BP and a Bxi1206D amp and then a PDX100.4 what do i need to do to so i have adequete electric power to have it all run???and if yall have any product suggestions please feel free...but i am only 17 and just graduated high school so i aint the richest kid around.

Hey, Im getting my sub on monday and I would like to start my build as soon as it comes in and i need to get some enclosure designs for it. I'm looking for at about 2cu. ft. with an L port tuned to 33 hertz width i can go as wide as i need so thats not a problem and length also but i cant go past 18 inches in depth. can somebody help me come up with something

i need a custom enclosure if anyone in here stays in cali n builds them hit me up i need an enclosure(ported) for my 2 FI SSD's

Hello everyone well I just orded 4 Q15s dual 1 ohm and bp power the box im building will have 2 seperate chambers, with 2 subs per chamber, with about 5 cuft per chamber,is that enough space?this is a sealed box. Also i will be using 3/4 inch MDF board to build the box, I will be putting double layers on the baffles, should I double layer all the other sides of the box or should I just brace inside to the single layers? thank you .................Brian

Configure Speaker: Ohm: dual 1 dual 2 P Chamfer: no yes +$10 Cooling: no yes +$40 HiXmCoil: no yes +$20 Daily or SPL: Daily SPL Induct Heat Ring: no yes +$25 Universal: no yes I can't seem to find what these options mean and/or how eeach affects the end product and I would like to order a couple of the Fi 18" BLTs. I will be playing them daily. Does anyone know where these options are explained so that I can decide what to choose and why?

What is the Induct Heat Ring and what is its pros/cons?

i want to get a 15" BTL and put it in a 1999 dodge stratus. i cant decide if i want a ported box with the BTL firing at a 45 degree angle towards the trunk and have the port firing towards the seats (i currently leave my back seat down, it is MUCH louder). OR go with a sealed box with the BTL firing towards the seats with my back seat down. i was thinking a Hifonics Brutus 2406 for it, which is 2,400 watts RMS at 1 ohm. i would get it fully loaded. PLEASE MAKE ALL THE RECOMMENDATIONS YOU WISH! another thing is the new BTL's, there is no triple stack magnet!?!?!?!?!?!? it is just a single magnet, why would they to that???

Well i asked quite awhile back what i should tune to if i wanted a loud daily listener, and most people stated 33-35 hz. It turns out that the box i've made is 34.97xx, so i just want the final word from people before i seal up the box and have to live with it. I mainly listen to rock and rap, and want it to be loud, but won't be visiting a TL anytime soon. Edit: Sub: 18" Bl. Box: 6.3 cu ft, tuned to 34.97xx. amp: would love sundown, but may have to settle for a bxi2006d (which would be alright for me, just would prefer the sundown)

i'm looking to run 2 btl 18's in 12.09 cubes gross in my trunk for daily. lmk

hey guys... i am trying to find out the T/S Parameters of the Copper Coil Option. i was looking at the Fi site and thought it was weird that the BL rating was so low when compared to so many other drivers. would a very low BL rating not be ideal for Porting? i was considering doing a PR or Porting the box, but i was told by the guys at AE Speakers that a low BL # leads him to believe that it is not a good candidate for porting or a PR. does anyone have decent experience in porting the copper coil SSD and what results have you had?

i have had my fi q installed in my car for a few weeks. today i was listening to it pretty loud, but nothing too crazy when all the sudden it stopped. my power light on my amp is still lit up (jl1000.1), all wires are connected. any advice or thoughts on what happened?

I wanna get a box built for my civic but don't know wtf to look for. Ok some info I plan on getting 1 fully loaded 15" btl when they update the site, and I wanna run at the most 2000w to it. Right now I only got an 800w amp but I plan on upgrading to a rockford fosgate t20001bd within a month. I also wanted to go ported instead of sealed on the box and I'm not to sure what Hz I should go with. Damn I feel so loss but I guess we all gotta start somewhere. So I'd appreciate the help and if more info is needed I'll give it. Thanks in advance

i know this is a real noob question but what is the cutout diameter of a btl 18"?

I was originally talking to Scott about a Q 18 in my h/t setup, but I have a chance to get a used SSD 15 instead. It needs reconed, so I was just wondering about the best coil for the recone, and a few questions. I was planning on asking for the copper coils with the recone, but I was just wondering if it would be best with my setup. I was goin to use one of the following plate amps with it, so around 500rms at 4 ohms. Bash 500 http://www.partsexpress.com/pe/showdetl.cf...tnumber=300-752 Dayton 500 http://www.partsexpress.com/pe/showdetl.cf...tnumber=300-806 At the moment I'm leaning more towards the Dayton, but I wasn't sure if it was worth the price difference. Also cou…

Hey. I going to have a 12" ssd with copper coil and the kicker zx1000.1 amp and i was wandering if i would be alright using 4 gauge power and ground wires because thats what i had for my old setup which wasnt as powerful...or should i just run 2 gauge wires???

This is my first time to mount a sub (have to learn sometime, eh?), so bare with me. The screw holes, when i look through them, i see the foam/rubber that extends from the surround. If i stretch the circle with the screw holes, i can barely get past the outer rim of the basket; making it impossible to screw the opposite side in. SO my question is, how exactly do i screw (or bolt, undecided) the thing in? I know to pilot/predrill my holes, its just i dont know how to safely do it.

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…

Well, i've figured out that I can fit a 5.5 cu box in my trunk, now i was originally going to go with two 15" btl's but after taking measurements, it seems like my trunk would be more suited for two 12" btl's. My question is, which would sound better/be louder/hit lower freq's better in a 5.5cu ported box? they will be tuned at about 32hz Any help would be appreciated, thankss

Hey all, Today I just got my 12" BTL and my Crunch GP3000D along with my custom box and I installed everything today and to be honest I am not impressed with this subwoofer at all. Like when the subwoofer hits, it sounds like it is bottoming out and I dont understand why. I use to have 2 12w6v2s to a JL 1000/1 and it was hitting WAY harder than my 12" BTL. I just met my friend who I sold my w6s to and he was running them to a Kenwood amp pushing 600rms to them and they were slamming compared to my BTL. I just am not impressed with the performance of the BTL at all. It cannot pick up anything high at all. I know it is a SPL sub, but I have read tons and tons of peoples rev…

got my sub couple of days ago and need a design. its going into a 99 cadillac escalade so theres plenty of room... can you guys help?? listen mostly to heavy rock and some rap.

does anyone know right off what diameter the sub cut-out is for a nice tight fit thanks

Quick question...I've had my heart set on the 12" Q (after much reading on this and the BL) with my main intentions towards sound quality. Im putting this in my trunk of a jetta and my question is.....is the sound quality going to really be that prevalent through the back seats? Maybe i shouldve gone BL? thanks in advance
