Fi Technical

In my van. I'm running a rockford fosgate p8002 with zero guage wiring to my 18" dual 2 ohm p chamfer BL at 4 ohms about 800 rms. I was wondering what i should have my amp at for gain and frequency i got about a 6 cubic foot box not really tuned. all i listen too his rap. I just want it too be super loud. i'm borrowing the box from a friend while i'm building mine. thanks alot

i have a budget of $500 for an amp can anybody tell me what would be better for a 18" bl and 18" btl i will appreciate any help from anybody. thanks, Jose

can someone please help me out here? i need a box design for TWO 12" Fi Q's!! tuned to about 33 hz. and the dimensions (height) should be able to fit in an 07 altima with limited trunk space or theres no point lol. thanks a mill

Ive got 2 BTL 15s and i wanted to make sure my calculations were correct before i started building. The total room i have to work with is h=23 w=24 l=39inches. Total internal volume is 10.5 cubes, and after all displacements i have 8.65 cubes. the port dimensions are h=22.5 w=4.5 l=18.4 which should make the box tuned to 33hz. can someone check this for me to make sure i didnt make any errors. Thanks Keith

My space is 39" wide and I can go 20" tall. How deep do I need to make the box (and how long AND wide does my slot port need to be) to have a net volume of 4-4.5cuft and a daily tuning of 30-33hz? Power will come from 2 sundown saz1500's strapped at 2ohm. Thanks

like it says want to build another box for my btl if someone could help with some tuneing and a 3rd dimention it would help thanks. Oh it would be a 1/2 wall can go 36X20X?(maybe 24 to 30 inches) external and would like to tune to 36hz feel free to PM me or answer here also there will be 6 in internal radius corners on the backside and matereal would be 1.25 in thick. Thanks for any help MC

All of my subs I own have the positive terminal on the left and negative on the right. Whether they be single or dual they are always in this fashion. I ordered a 15 sexxx recone for a se and a claw basket. I also ordered new terminals and wanted to make sure that I'm not going to install them incorrectly. My glue should be here in a day or so(I hope) and would like to start when it arrives. Thanks CJ

Can FI do this to my Conecpt PT's? Sorry that i posted this but im sure someone can answer me faster then emailing them...

Ok so im about to order 2 12" Fi Qs and just want to know what setup i should get. im thinkin on getting a JBL GTO14001 amp for it, is that ok? also... i need to know if i should get an extra battery or cap for it, if so what kind?

Could somebody tell me what the diameter of the magnet is on the 12" BTL. And, what is the mounting depth of the same sub is. And one more thing, if I build a box that is 5" at the top, 11" at the bottom, 20" tall, and 40" wide, will that be enough room to fit a 12" BTL with just cooling(will it be deep enough)?

I got a guy interested in buying my Fi Bl motor, but i dont have a clue as to how much to sell it for. The motor is practically new with nothin wrong with it. Any idea what price i should sell it for?

Can I get someone to assist me with an enclosure design for dual SP4 18s. Max dimensions are 27L x 30D x 30H. I'm currently running 2 15s and wanting to go with 18s. Power is a non issue since I'm now using two Crescendo 3.5ks. If this is possible please let me know. Looking to order the subs this week.

if i have round 8 cubic feet will two ports be ok? two of them at 3 inche's by 21? thanks for any help guys!

ok i order a 15" fi btl fully loaded with a dual 2 ohm. i have been researching a lil bit and im confused.... i will be using a sundown audio saz2000d for this sub how do i wire the subto my amp ??? should i have order it dual 1 ohm?? im confused///

how big of a box should i build for 2-12 btl? It will be powered by 2-40.1, i was thinking 4 cu at 35hz bad idea?

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 bought a fi q 12 last year. I bought it with the intention to put it in a ported box. I have a genesis, the box is wayy to big for my trunk. I kept the sub in my garage until now. im planning on making the smallest sealed box possible for the sub, which i beleive is .8 . I selected a whole bunch of options, cant remember which ones though. Are there any options on the fi website that says the sub would have to be exclusivly for ported boxes? I know they have the high qts option, for sealed boxes. Im not too good with all these subwoofer terms, lol. I just want to know if i can put the sub in a sealed box without worrying im going to mess the sub up.

Hey guys, I have Manny from http://www.trexcaraudio.com/ building my box for 2 18" btls..and I was just wondering if this sounds correct, his calculations for the box: 19" high 40" across 37" deep 95 sq ins port is 13" long (tuned @ 32 hz) and is 11.79 cubes thnks, Freddy

i have around 900wts at 2 ohms looking to do a single 15" ported box. listen to rap and classic rock. which would work best a Q or ssd wth copper vc.

Will the new sundown sae 1200 coming out in november be too much for a 15Q loaded?

Would any one happen to know the diameter for the BL 15.

I was wondering if the specs are close enough between the two subs , that can I use my old box (really not old, 3 months) to house my new Fi 18 inch BTL Sub.

Im purchasing 1 fi btl n2 18 inch, and im not sure whether to choose dual 1 ohm or dual 2 ohm. I have a 4000 watt mono amp with a lowest possible rating of 1 ohm. I used to have 2 12s but im moving to this 1 18 inch and wish to have it running at 1 ohm. Ive read around and from what ive heard, i should go with the dual 2 ohm sub, but i wanted to be sure before this purchase. thanks for your help

Does anyone have plans for a ported box for a Fi 15" Q? It will be in the back of my 06 impala. I can post the dimensions of my trunk later, but any help would be awesome. I was looking for something tuned around 30-35 hz. Basically, I want something thats gonna really make my Q slam because all I really listen to is rap. Thanks.

Hey guys im looking to try out the maxx link but i have a question for ya. Im gonna be running 4 kicker zx2500.1 amps and 2 18in Btl dual 1 ohm subs. The zx amps are 2 ohm stable and i was wondering if there is any possible configuration to have the amps see a 2ohm load once strapped. Also would i be better without the maxx link and running each amp to each coil? What ohm loads could i see there. thanks
