Fi Technical

I have 2 D2 18inch Btl's and 2 SAZ 3000ds I need to know how to wire the subs down 2 ohm, because i'm strapping the amps together.

I need some 2 cents on my new setup which will be 2 Fi Bl 12's fully loaded. im going to have 2 1700 rms watt amps total 3400rms. i have a 125 amp alternater and a redtop battery. i was wanting to keep my stock alternater for low funds reasons. for now what can i use to power the subs? could more batterys work for now?

Hi I need some questions answered on the x12. I need some input on what size and kind of box to put it in. I have a phoenix gold xenon 400.1 to power it and I listen to a lot of bass heavy music ( rap, chopped & screwed, etc.). I know what the website recommends but I would appreciate any input or suggestions. It will be going in a 1995 neon 2dr. Thanks!

Gday all I am running two FI Q 12" D2's in a daily driver with a box that was built for it by a local car audio installer using a single round port. Sounds reasonable but no where near as loud as I expected from these speakers. I am driving them with a Hifonics 2k rms amp Boot mounted Optima inline with another optima under the hood. Also have a 2.5 Frd Cap. This is a boot mount install in a Aussie car Called a XR6 Family sized four door sedan.. ATM I have the speakers behind the back seat pointing into the car and the port facing the same way. Metered this setup at 132.5 before i upgraded the batteries seen alot better scores out of single speaker setups with similar siz…

I need to recone my BL and was wanting to know if I can recone it to BTL using the double stacked magnet kit.

I have my wood and screws and im getting some wood glue do i need anything else?

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

i am planning on hooking a fi bl 12 up to my kicker zx 1000.1 amp which is 2ohm stable. do i buy a dual 1 ohm sub or a dual 2ohm? please help! thanks

i'm powering 2 Fi Bl 12's. i would run one amp per sub. these amps run 1550 RMS at 2 Ohms. does Clarion make good amps? would you recommend these? budget is also a key factor. and i can get these amps incredibly cheap. i'd run Rockford if i could. but i cant afford it.

Why is the recommended tuning frequency for the Q 18 so low?

So I just recieved my 15" SSD with copper coil in the mail Thursday. I originally planned to go sealed in about 2cuft, but I have about 3.1cuft after all displacement to play with, so I was thinking about porting it. I wanted the install to be strictly sq, so I was thinking about 28Hz or so. My question is, has anyone here tuned it that low? If so, how's the sound quality? And if no one has, what tuning would you recommend for a sq setup?

Looking to build new system. Planing on using a Memphis 2500 watt amp to each sub. This system will be mostly for SPL but also some daily listening. Will be using 10" or 12" subs. Just wondering which Fi sub would work best. Will start with 2 subs but move to 3 at a later time and maybe a Memphis Mojo 4kw to each also.

the topic asks it all.

Im looking around locally for a place to build a box for 2 15's. Ive heard of a place called precision audio but I'm not too sure if they use quality material/planning/preparation/etc. All I know is they charge about 250-300 for a box. Does this sound reasonable to you? I know there are a whole bunch of variables but judging from your past purchases and stuff, let me know, thanks.

I haven't built it yet I am just exploring options and found a design I kind of like. 8 cu. ft. tuned to 34 hz with 101.25 square inches of port. The port opening will be 4.5 " wide and 21.5" long. The box dimensions are 33x24x27.5 overall. It will be a crx style box , and will go inside of the cab of a 2000 chevy silverado. I plan on pointing the port towards the driver's side and have the sub behind the passengers seat. Do these specs seem alright to everyone? Would a different direction with the ports yield better results? Does that tuning seem alright or should I go lower/ higher? I want SPL but also enjoy the low notes that a highly tuned box sometimes lack. If any…

Hi! I from Russia, me interest cost recone kit BTL12, 0.7 Ohms/coil ? Whether it is possible to deliver in Russia?

I was going to order these options: D1 Cooling Flatwind Daily Do I need Extreme lead? My setup will be 2 18" FI BL connected to Sundown 3000D. This will be my daily setup. Thanks,

ok, just installed my new 15qd2 with bp today. 4.8 cuft ported at 28 hz...rockford p1000-1bd. yes thing slams louder then i could have imagined. only one problem. i think i will be able to get rid of most of the trunk rattle, but it's the sunroof then driving me nuts. i need to get an sd card reader to load some pics and vids from my phone... every time i start playing some really low notes, the sunroof starts banging so bad that's about all i hear inside. anyone have this issue or know how to fix it? any ideas would be great! oh yes it's a 99' infiniti i30.

Hey I'm hoping to have a Sonic FX Q 12" very soon (assuming DHL can find it ) I was wondering if you guys could recone it in the worst cast scenario were it gets blown??? It is very similar (practically the same thing) to Incriminator Audio's Death Penalty series, (in case you don't recognize the sub). I was just wondering what soft parts you would use in reconing it??? BTL, BL, Q ???? If you need more info on the sub let me know and I'll try and find it for ya. Thanks! Jon

I think I'm gonna add another sub soonish and am hunting for an amp. My budget will be around $150 and was thinking 500 watts total. I'm going sealed. I have ~160 watts on this one now and it gets loud which is why I was gonna add another with a little more power each. Or would I be better off just getting a bigger amp on the one I have. My budget may go up some just depends on the amp. Definitely not over $200. I have 4ga wire running and will need to put an amp on fronts. I have a 4 channel now running entire system. My car is a 2011 Honda civic systems in Sig. If I'm a noob and you have questions just ask

Would there be any noticeable difference between making one huge box or leaving both of them in separate boxes, advantages? disadvantages?

I'm currently trying to design an enclosure for 3 Bl 10's i've got 1.85cu.ft of volume (total), with displacement. What sort of port area and length would i be looking at. Also, i can increase the volume slightly, as that is with 1inch MDF

ok, I'm about to attempt to build my first enclosure for Fi Q 12. 1.9ft ^3 tuned 30hz. Where can I get demensions and what items do I need. Such as brands of glue, type of screws, etc. If I Take mesurements to Home Depo, Will they cut the pieces for me? Is it difficult to make a Enclosure, I read that its pretty easy.

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

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?
