Okay I just recieved my two 12" SSD with copper coils about a week ago. I purchased a very large sheet of mdf yestarday so I'm set with wood. I also just purchased a US AMPs XT4000D so I am also set on power. This is my first time building a box. I am going to be putting the box in the bed of my avalanche so I have a boat load of room. I was going to tune to about 32 or 33 Hz and do 2.5 cubes per sub. This box will be ported. If someone could provide me with diminsions that would be awesome!!! or even a plans. My friend who is going to be helping me build the box (he has experience building boxs) said he will help me. Thanks a lot if any of yall could help me!!!!!

I wanting to run 2 12" Qs in a sealed box under the seat of my 07 crew cab sierra Theyll have about 1cu ft of air space each. Im wondering if the SSDs would be better for this type of enclosure or what? Ill be running a RF Power 800a2 for right now and upgrading later to probably a RF T15002

I'm too lazy to type another thread so I'm just going to post links Pics and vids here: http://www.caraudio.com/forum/showthread.php?t=293273

Would 2.3 at 33hz be good for a 15 bl.

I need help deciding which amp i should get... i used to run the soundstream xxx6500 (which ive been told only does about 2700 @ 12v and 1ohm) on my 2 15" BTLs (dual .7) but i broke my box.... so next week they are completely redoing it to make it much stronger. but since im redoing that, im going to just uppppp the power. the sounstream is sold.... now for my amp choices i can either get: (2) opti4000ds and run them at 2ohm....doing right about 3000rms per sub (which was my goal) i know this amp is JUST like the SS, but its regulated so it should do more power on 12v as opposed to the SS. or i can get (1) AB500.1 which will do about 4700rms and costs about $200 less. the…

i went to the local car audio store and one of the employees told me that 15's are unable to play very many rock songs because they "simply cant hit those notes, its impossible" he said. was this guy just feeding me a ton of bs to sell me his product or did he know what he was talking about? ( he also has never heard of FI ) ive had my heart set on two fi bl 15's but after that i dont know if i should reconsider and get 2, maybe 3 12's or even like 4 10's? ( kind of exaggerating, but not completely ) ive got a ford explorer so i have the room to fit this amount of subs.

Ok everyone, just finished everything up, the X series are up and we are doing free BP cooling upgrade on them. We are doing free cooling, p chamfer, hyper pole and voice coil upgrades(flatwind/high xmax) on all our sub purchases as well as free shipping to the cont. US. Enjoy the sale guys. -Shawn PS it has been a long day, Im tired and Im finally fixing to go to sleep.

So I just finished installing an fi q 18 in my car! Thank you Fi for such a beast of a sub. Pics to come!

Like the title says, one of the magnets on my 12" Fi Q split in half. Don't know how, but I noticed the woofer was making strange noises a week or so ago, and took it out to investigate. I heard that this wasn't exactly a unique case, as other Fi products seem to have split magnets as well, possibly UPS is dropping them? At any rate, who do I contact for help? I have emailed Fi with no response. Is there anyone on the forum that could help speed this up? The sub is still covered under warranty, if this issue is covered under warranty...

Alright so im going to have a pretty big box in the back seat of my quad cab, 35w 31h 17d before displacement of the sub and wood. The cab in a 99 dodge really isnt big, so its a big box and big sub in a small space. What do you think the tuning should be? i want it to get loud and low, and i was thinking 30hz. (actually like 29.7 or something) opinions? Also the sub and port will be on the 31x35 side of the box on opposite ends. Or should i center the sub?

I have a 18" bl and one of my tinsel leads recently broke. How do i go about fixing it? I'd prefer to send it to Fi if possible but am having trouble getting a response. Hopefully scott stumbles upon this. Thanks -Jeff

Ok I have a friend gettin two alpine mrp2000 amps each pushin about 2248wrms at 2 ohms and hes running that to two alpine Type X 12s.. Now me being me I just wanna 'keep up and surpass' him and Im gettin 2 BTL 12s with a Sundown 3500D but I dont have either yet.. Will my car still be louder? p.s. I plan to have 2.5^3 for each sub and tuned to about 35hz

ok i have 2 18" BL subs dual 1ohm flatwind cooling and pchamfer these are the first model bl's. they are going to see a sundown 1500 to each sub what is the smallest box ported that will be ok for these subs. i want to keep the box under the rear deck in a 1995 fleetwood. between the hinges, theres trunk rods in the way. i'll invert the subs to get a lil more airspace if i need to. just need to know whats the smallest the box can be and sound good

I normally check out Fi's web site at least once or twice a week. I have to say I was pleasantly surprised to see the updated look. Check it out. https://ssl.perfora.net/www.ficaraudio.com/...ndex.shopscript Chad

Im thinking about going with 4- 12" ssd's, ive got around 6 cubes to work with and 3000 watts, do you think the subs would get off like they are supposed too?

Hi Guys, Ive been using my BL's for ...i dont know 3 years or so. Awesome drivers. BUT I pulled them out the other day and the motor is showing signs of rust. Not nearly as bad as the terminals on the shitty Samsung TV after a year, but its there. Now I live at the sea and things do go bad around here. How much would it cost to rust proof these things. Maybe can add a few extra options such as Powder-coating and using Stainless where possible. I could post pics, but the fact is they still play just fine and its not nearly as bad as this post might make it sound; just sad to see rust on my babies.

Fed Ex stopped by today. Oh Yeah, Had to take a peak before setting it under the tree for Christmas.

If you read my other posts, you pretty much know what I want. I am doing a blowthrough in the bed of my truck. To save some room, I am debating on doing either 2 15" BTL's or 4 12" subs. I know no matter what I do I am gonna need an upgrade electrical wise. I have already decided on a 300 amp alt no matter what I do (wanting to be extra safe) and big 3. Here is where the question kicks in. If I do 4 12" BTL's, how much more ($$$$ wise) would this costs in upgrades (batteries, etc) than if I did say 4 12" Q's/BL's or 2 15" BTL's???? Also, SORRY 4 BEING A PAIN, but does anyone know if Hifonics amps are good, mainly looking at the Brutus at the moment. Not bad price, …

Does FI stock 2.5" coil re-cones? Specs on the coils? Might need a bunch of em

I know you have old parts laying around from subs you have worked on in the past. Any chance you have any RE RE series voice coils laying around? Yes I realize they are cheap subs and probably not worth the recone. I think I bought them for 56 shipped each(4). But if I get bored one day it could be fun. Anyway, let me know. If not no big deal

I am interested in having a couple of subs recones to 15's or 18's i would like a price quote for them if that's possible.... The first 2 subs are RE SX's TC9's and Hp3's Thamksa lot!!!!

ok i ordered a 18" BTL and was going to hook it up to the new hifonics brutus brz2400. Is that too much for the sub? but i also got the sub at a 1ohm so i can hook the amp to 2 ohms. Also will i be able to put that 18" in the back of my 2001 impala?

ok first I did see the other post related but said not to reply anymore. anyways I bought my 2 fi bl 15's on oct 12th and only recently recieved an email saying they are awaiting fufillment, does this mean the order did not get started until i got the email about the order? I know they are busy just trying to get an estimated time frame to work with here

Like it says up there, Ive always like the RE SX type dust cap/cone because it so seamless and seckserific. Just wondering if Fi plans on doing that and how many other people on here would like that option?

Well, my homie wants to run a good amount of 12"s, or possibly 15" ssd's But he wants to do a blowthrough from the bed of the truck to the cab, what would be the best way to do it? He's thinking about doing it in sections, and i think that the way that might be best is to do 4 15"s SSDs and a SAZ 4500 and then do 4 more and another SAZ 4500 but, would you have to do a band pass pretty much??
