General Fi

This is my first post here. im building a sub box for a 15" Fi SSD. it hasnt got here yet and i need to know the cutout diameter for the hole that the SSD goes in. the box is 4 cu.ft. tuned to 38hz

ok so i know this is probobly a dumb question but i have to ask. what is the best series of sub to buy for a daily bad ass bass machine? to fill it in for you here we go...... i have a 86 bmw 325E a friend and i did everything ti this car as a team effort. it has two mephis 5 1/4 on a 2 channle ads, 2 orion 6x9's on a orion 225 and (had) 2 soundstream t4's 15's in a 10 cubic foot box, round ported, tuned for 35 hrtz. the car has two huge glass matte batterys and a 320amp alt on it. now the subs were driven bt a orion d1200...... obviosly way under driven, but it purduced 130 dbs on a normal song ( blur berry yum yum by ludacris). so the one sub re burnt the voice coil and…

I have a few questions about the Fi BTL sub" 1) What is the difference between choosing the options Dual 1 and Dual 2? Ex. Would i have to buy a certain amp if I chose Dual 1 or Dual 2? or if i get 2 subs would i need 1to be dual 1 the other to be 1 dual 2 ? 2) Is there a warranty for the Fi BTL sub, if so how long is the warranty for? Thanks for your time regarding these questions, Alex

Ok so as you can hopefully tell I have a Dodge Charger. I have some trunk room to work with. I have 2 12 inch fully loaded SSD's being built right now I just got my 1200d Sundown amp. I know Chargers have a pretty good alt but I will of course still do the big 3 and maybe another battery. I would just like to be around 13v or a little higher. I read on Fi's website; "Ported box we recommend using 1.8-2.5 cubic feet @ 33Hz (this is optimal in our eyes and to our ears, you can tune 31-35hz fine if you so please)" So is that easy? Should I just go with a 5 cuft box ported and tuned at 33Hz???? What do you guys recommend? Thanks!!!!!!!!

I have a fi 15". Idk what one this is? And help?

hello this is my first post here..i just got 2 fi bl 12's they are not here yet...but does anyone know what kind of db i can expect from these??

I ordered a BTL 18 today, dual 1 ohm, and I was wanting to see if I could change it to dual 2. I'm using a RF T-1500, and I got to thinking that with the dual 1 I would either be able to run a half ohm load or 2 ohm. I'd like to change it to dual 2 since the amp isn't stable at a half ohm. My invoice number is: I-14072/00 Thanks for the help!

i just wanted to know before i ordered, is the cooling option important to add to the 15"btl for a daily sub?

I want to buy/make a Fi polo. I didnt see one on the site has anyone done it before i want the design. I cant figure out how to get just a black Fi logo on a dark grey one. I would do it if i had photoshop but i dont.

So I sent an email to the sales team weeks ago and haven't had a reply and sent one to nicks personal email is there any other way to contact these people im ready to buy and need to know how much money to allocate to paypal and give my address. Any ideas on how I can make this happen? Its a Q 12" that im after btw fully loaded with BP and cooling Cheers, James

I'm going to order a BTL 18 1-ohm after I order a T1500-1bd. I was planning on getting all the options, daily, and universal. I was just wondering if there's any downside to getting the universal option. Thanks for the help.

hey guys, if you checked out my latest vid i posted a few days ago then you will know that people have been saying it could be hitting harder, but im confused here because on some songs the amp clipping light comes on so it would be sweet if people with more knowledge could help me out so if you guys could show me what the gains should be set to, to have the loudest possible beat that would be much appreciated here is the vid here are my current amp and H/U settings (the red dot next to each setting is where the gain is set to) Box = slot ported tuned to 32hz Amp = AQ2200d Sub = 18" BTL D2 Head unit settings Sub lvl = 13 (max 15) Bass lvl = 0 Tuned at 30 volume with 50…

so i am trying to figure out which sub to order, i have read multiple posts about this and in the end the person purchases a sub but with no reasoning on there conclusion. so here is what i have to work with. i do alot of offroading so cargo space must be maintained this is why i have chosen the box below. the box is made for a single 10" with .75cuft. i have been wanting a Fi woofer for sometime now. so like the other posts which one and why? pros and cons. both the Q and SSD are rated for sealed enclosures. i would like to run the 10" Q. i would probably run the sundown SAZ-1000D. here is a few pics of the box.

Anyone know what RMS will be on these when they go on sale?

i have a 3 inch by 12 inch port that goes in 9 inches which means its tuned to 32 hz ... if i maybe woulda made it thinner and went back farther could it of been louder?

I RLLY neeed help i just hooked up my brutus to my fi ssd 18 and all its doing is go thud thud thud thud thud thud thud nonstop kinda quickly with no music bass coming from it idk wtf is wrong with it if i take the RCA out it stops please help.... i hooked it before and it worked fine but someoone broke into my car and ripped everything out but they caught them and i got it all back so idk just any suggestions

This time its in daylight and is much shorter because people complained on those points last time haha Although this time im driving and its not that easy to control the car and film while having that much bass ripping though the steering wheel haha Update on sub, its loud and insane, ive done several upgrades such as cleaned everything up, the big 3 and moved things around and I seriously could not believe what a massive differnce the big 3 made on how loud this sub goes! edit* oh and please rate and comment if you like, 5* would be nice

i guess ill go with the single 15" btl in a 5cft ported box instead of an 18" in a 6.5cft box i wish i had the air space for 1 18 btl but one of the members on this forum said by having 1 15 in its correct encloser v.s having a 18" in a 6.5 encloser which is recommend to have 5-8 cft per sub the 15 would be better to get the most bass. i hope everything work out right just seeing what you guys think. (1998 buick century)

just wanted to know what would be best from you guys wether i went with a single btl 18" or 15" for my car (1998 buick century) im confused. my custom box is already paid for my installer needs my car for a whole day so i still got time to pick the right sub for my car im just confused

So i got a FI BTL 12, AQ2200D amp, 0 guage kicker wire. Optima Red top under the hood & an extra " dumptruck battery" ( if you will) in the back. JVC KDR300 head unit. & I HAVE NOT done the big 3 yet. anyone got nay advice so i can get the full 2200 watts out of the amp without clipping the sub due to voltage drop?

i like how i get my first 18 and it doesnt come with a template for the size hole... i built a box for it before bt it was way off and i just lived with it ... what is the best way to cut my FI SSD to fit in the hole like a king ??? any suggestions would be appreciated

Im getting ready to order three fi ssd with bp option, but i want to make sure i get the right ones for my application. I will be running 3 of the 12 inch ssd's off of 2500 watts at 1 ohm. my question is, do i need dual 1 ohm or dual 2 ohm subs? What is the actual coil impedance? Are they dead on 1 or 2 ohm, or are the impedances actually lower or higher?? I want to do 3 dual 1's ran in series and then paralleled all together at .67 ohm, but if the actual driver impedance is lower than 1 ohm per coil, the total impedance may be a lot lower and i don't want to risk burning up my amp. Now, on the other hand, if i go with dual 2's and wire them in series then paralleled all …

i have a 1998 buick century im getting a box build for my trunk for an 18 inch BTL, but one problem my back seat dont let down. i can't take it off because i have kids just wanting to know from you guys would that 18 still sound good with back seat being up?

i was wondering if there was a way to find out the shipping with out going through the whole checkout process.
