Fi Technical

hey anybody that has a Fi BTL leave me a comment what kind of amp you got and how much watt and rms it isss thanks

I'm getting a Fi btl 15", could I please get some suggestions on a variety of amps i could use to push it . Thanks in advance

will a lanzar 4000 watt 2 channel amp (2 x 1650 rms at 2 ohms) blow these 2 Fi BL 15" subvwoofers with the cooling and flatwind options and the daily option at 2 ohms Basically can these subs handle that much power??????

Just as the title says, I may be getting 4 Ssd 12s in a trade and I'm. Doing a blow-through in a Toyota pickup and was wondering if they. Would perform well in a 4th order band-pass. Thanks

Can someone answer this question for me; I see that they offer a lot of upgrades, but each one will affect the parameters and driver's behavior. It would be nice if they offered updated parameters and more information on each of these upgrades. Adding mass to the assembly, then adding spiders and changing spider packs, changing coil assemblies, and materials etc, does quite a bit to affect the driver's behavior, from altering moving mass and resonant frequency, causing QES changes, and inductance variances to causing shifts in the CMS curves... All these things really affect the driver's behavior as a whole, the way it will sound, and they even affect the enclosure design…

hey i was just wondering what would be a good amp to run 2 18 in BTL off of for my 2002 chevy avalanche and does anyone know if everything necessary will fit? right now i have 2 12 in alpines back there.

I am planning a new home theatre to replace my mirage system for my new house. The room is 15x19 with 9' ceilings, and there are large openings into the dining room and it is open to the front door entrance and hallway. This will be used for about 75% HT/TV and 25% music. I am going to switch to a pioneer elite vsx-23txh with 3 elemental designs A6-6T6-MTMs as my FL, FR, and C channels, and probably some A3-5Ts for the RL and RR. I will be needing a sub as well and would like to make one to save some cash. I was thinking about doing an IB3 15 or 18 on an ED LT/1300. Just wondering what type of box to do, have seen them in really big sealed and ported enclosures as well a…

Need help with box specs and design for an 18btl. It will be going into a 2002 jeep grand cherokee. The space that I have available is 40x23x16 (w,d,h). I want the box to be tuned to @30hz. Sub will be powered by a planet audio bb2400.1 I would like the sub to be facing up with port firing back. Any input that you guys can give me would be greatly appreciated.

Would you recommend multiple ports are a large single port for 2 Q 18 D1s with cooling and the extra spider on an AudioQue AQ2200d, in 20 cubes after displacement tuned to 28 Hz? Car is a 2004 Tahoe with the max box dimension limits being about 27 H x 49.5 W x 36.5 D. I had a few designs floating around, I think one was with 4 8.5" round ports, one with two slots along the bottom of the box, and one was a rectangle in the center measuring 15.5 H x 19 W, so 294 in^2s area and was 22.35 in. long. The dimension limits leave about 7-9 inches between the box and the rear, 7 at the top and 9 at the bottom. I was thinking the large port might not have enough port speed, but …

I have been searching all over the internet to find out about qts (never even heard of it before i was looking into Q's this isn't my first system, i just never accounted for it before. it looks to me like it is highly dependant on what you are doing fi q 15's have the cooling and spider upgrade options, that is it i am going for sound quality with this build, dual fi Q 15 in a sealed enclosure measuring ~ 2.3 ft^3 per sub (after displacement and bracing of course) each sub will have it's own rockford fosgate t-1500-1bd giving them ~1350watts @ 2 ohms (already had one and just bought a second off a friend, who said headroom was a bad thing) they will be in the back…

To figure out the square inches of port area needed per cubic ft of volume, do I just multiply the vent width by vent length? And then I just take that number and divide it by how many cubic ft the box is? This is what I'm just guessing as I'm not sure of this. Please help.

ok i sent my sub woofer to get fixed with this information.... Fi Car Audio Attn: Repair Service 5450 Cameron St #104 Las Vegas NV 89118 Ive sent about 3 messages to fi and still nothing i got a email by the ups saying my shipment made it to its destination to get fixed but still no email from fi or somebody to let me know from the company that they have it or any info on getting my 15'' BTL fixed. With me not getting a email from fi im not sure who has my sub or after it made it what has happened to it. Ive been patient and all i wanna do is pay for them to fix my sub. Has anyone here gone through the same thing if so how long did you have to wait for feedback after you…

hey guys im really tight on space..the sub will go into a 2007 cadillac cts and id like to retain some trunk space..i know fi suggests 2.8-4 cuft for a 15..but whats the smallest i can go without suffering any loss in perfomance quality wise and output?

What amp is recommended for two 12 inch BL? I would like to not spend more than $400 but still get a great amp. Also what wire should I purchase for the hook up and also for the big 3 upgrade?

Hey I ordered a SSD 15 with both BP Power and Flatwound coils that I am going to be pushing 1000 watts through with a Rockford Fosgate Prime 1000-1d amp at 2 ohms. I was wondering if the box I have planned out with the RE calculator would work with my setup. If not, some advice would be appreciated.

I am thinking about getting an 18" BL for my 98 pontiac grand prix gt sedan. My car has a big trunk and I think it would be big enough for this sub and a good size ported box. I was wondering if anyone would have any advice as to whether this would fit fine and also amp recommendations? I would get the daily driver option as well. Im thinking around $400 for the sub and I could possibly build the box with my dad. Also what would be a good cap to go with it and would there be any other modifications I would have to make to my car's electrical system? I already have an alpine head unit.

I want to get a a pair of Fi ssd 15's and i am building a custom sealed enclosure for them, fi suggests between 1.5 and 2.5 cu ft per woofer, does this mean that 2 feet would be the ideal? this is my first time designing my own encosure and i would like to have the optimum internal space. would a 2.5 ft^3 make them hit any deeper or will they sound better with 2ft^3 (these volumes are AFTER displacement of course) i am really going for a sq build here please do not try to talk me up to the Q,, i am sticking with ssd's with the bp power upgrade the standard coils that being said i would love to be able to hit the low note in "put on" with this setup i am not incredibly…

The tech page says the cooling option increases power handling by 200-500 watts depending on install and scenario. Would I be wrong in guessing a sealed enclosure (in the neighborhood of 1.2 cu ft) would put it towards the higher end of that increase estimate?

Im wanting to build a box for my two 15's because i want to get my system term lab'd at a local shop and right now i have a fiberglass box but i want to make another box all out of MDF. so if anyone can help id greatly appreciate it.

Hey guys I have a question about the Q series woofers: a 12 Q in a ported box or a 15 Q in a sealed box is what I am debating now given a 2.5 ft box for either one: 1.) which will be louder? 2.) which will play lower? 3.) which will have better SQ for rock?

specs on 09 fi ssd 18

hi all. i have a bl 12 at dual 2 hooked up to a kicker 1500zx mono amp. its all hooked up correctly yet when i turn my car on the amp goes straight to protection. any thoughts on why it might be doing this? the only two problems i can think of is that my inline is a few volts low of the requierments, or the fact that i have 4 gauge wire and might need 0 gauge? the volts from the battery are only short by about .5 volts. any input or advice would be well appreciated!!!

I ordered 1 18" Fi SSD. I plan on getting another one soon. And was wondering what kind of amp I should get? I went ahead an got the dual 2 ohm voice coils on the amp. I'm looking for something cheap. Possibly well under $200? Currently I have a MA audio 18" 1100 watt amp with a legacy audio 2000 watt amp and it hits hard but it doesn't have near the quality I'm looking for. With the new SSD I'm looking to run either a 1ohm or 2 ohm config. Not sure yet what to do. Any ideas? I'm also wanting to run the SSD at atleast 650wrms 800 would be perfect.
