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?

anybody got any ideas for sealing up the space around my box going into the trunk

Thanks to everyone at Fi Car Audio. So much for 3-7 days lead time...Ordered Saturday and was shipped Mon or Tues. Decided to go back from the Aq Hdc315 to the new 09 Bl 15. It's great to have the Fi SQ back. And god does it just absolutely slam and hit the notes with absolute accuracy. Especially, during rock double bass. Ive seen little about the 09 BL so I thought I would post my thoughts and pics. This is my 3rd Fi sub and every time, I am happy about the money and time spent. Can't wait to put more time and it and see how she does after break in. Sincerely, Mike Giessen Mike Giessen Racing inc.

I took my sub (btl) out to test out another sub and then I notice it.....damn tensels ate into the spiders. I was wondering, do the new recones come with the tensels woven into the spider? And how much would it be shipped to austin texas 78741. I'll have to wait to get it but I AM A play this one out until it dies. kinda broke. thanks

So this last weekend I came home for spring break. I have a 15" Q and my brother has a 12" q. Saturday night my sub quit playing and I was a little drunk so I didnt worry about it. On sunday we built a new box for my brothers new truck(he unhooked in perfect condition 3 weeks ago) and by the time we installed it we realized the top magnet was cracked all the way around and shifted about a 1/8 inch, so the coil was grinding and sounded awful. We ghetto fixed his by beating the magnet back into place with a rubber mallet and siliconing it in place, now it sounds fine. The next day I went to diagnose my problem. I blew the sub when I was drunk when I turned my deck and b…

will banana plugs fit in the push terminal on the bl's

Which is louder for a single fq?? How is an 8th order like? I know 6th is ported in ported. I am trying tomake a box to peak extremely high at one note.

anyone have any specs for a 4th order bandpass box for a Fi Q 12"?

hey was wondering.. i have a btl coming to me in a trade with a fresh recone, but there is no basket.. can i purchase one through you guys? (18" 12 spoke, and a rubber gasket, and terminals) thanks!

Here is my video of Bass Boom Bottom by power supply. My 15" Fi BL is powered by an American Bass VFL 150.1 at 1 ohms...Just recently installed the Epic 160..Last night actually..Not finished installing, still need to fill in the gaps around it with some vinyl pieces...Anyway..Here is a quick video of it..On the Epic I am getting 142 db's with the back seats up..I do have blow through in my rear deck..But the seat is still Up..

So I got my 2 Q 15's installed in the box (7cuft @ 32Hz), running off an AQ2200D, and installed my 36sqft of Damplifier Pro (great stuff FYI) but I seem to be having a problem getting the bass into the cabin. I knew that I'd probably run into this problem with such a big box so I'm weighing my options now. The box is rear facing, and when I pull it within about 6"-8" from the back of the car the bass seems to be the "best", but I still have limited clearance around the top and sides of the box. The bass sounds extremely peaky at higher frequencies (60-80Hz) and I believe this is because the trunk is actually functioning something like a double vented bandpass and blocking…

ok everyone I just installed my 2 - 12" fi Bl's running off a RF 2000.1 ....Tomorrow (6-17-09) there is a local car show thrown by a radio station in my city and i would like to enter into the "bass-off" and "bass-race"competition. this will be my first time doing any competition like this and i would like some advice on how i should approach it: such as .....should i play music or use like a bass cd or even use like a test tone cd. am i supposed to have the windows up or down? (i have a ported box BTW) i have a 2005 impala ss...should i fold the rear seats down? i know it seems like alot of questions but i figure this is the best place to get some honest answers. T…

I am buying a bass maximizer from audiocontrol. I needed to know if I needed two sense I was getting two amps or would one be enough.

got my FI bl 18" metered today @ 141.1 db on music with a single stock battery. i dropped down to about 137.0 db within 10-15 secs. will a second battery give me a lesser or greater then a 141.1 db? going to fix box as well. (baffle,bracing, rounding off, ect.)

Also curious about this one. I have had some cheap subs in the past with horrible bass response. How do the BTLs stand up for bass response. I have a friend with RF P3's in their "special" enclosure (the plastic ported box) and I have noticed that a lot of the bass notes are jumbled together and don't stand out from one another. Since the BTL's are some big SPL subs, do they do this as well or are they a little better and letting the notes stand out.

anybody got any download links for different continuous frequency bass tones for competition use maybe 35-40hz

Hello everyone, Ok so im thinking about adding a second battery in my car in the trunk to maintain voltage drop. right now iv got a red top under the hood, about to do the big 3 and a 120a stock alt with a rockford t10000bdcp and a alpine pdx f4. Im planning on getting a kenetik hc800 in the back to add a little more power to my electrical. What i was wanting to know is would this work properly and just add power to my electrical or will it burn out my alt or anything?? i know iv heard of people adding a battery with a stock alt and was thinking it would be fine because i really dont want to spend 600 on a ho alt right now. my local stereo shop says i need a bigger alt an…

Heres the install vehicle. http://www.putfile.com/pic.php?img=3306527 Heres the problem. These brackets each have 2 8g runs coming into them. Anyone else ever have this issue? The battery bay is rather small, so choices on aftermarket batteries are limited. Help is greatly appreciated.

Is it possible if I can call you or would you prefer for me to ask you on here as I have a rather set of questions and not just a few...

Well with the end of summer and working 70 hours a week at my summer job on top of building a car i will finally be back around more often after next Thursday. Just got back in and moved to college and we've got to wait until late next week before we will have internet access... Hopefully my presence will be more noticed in the next few weeks as i get back into the swing of things and not running every which way but loose.. I have not been able to answer any of my emails due to them being server based and without having an isp i can't download and reply to all of them...i had quite a few stored on my cell phone from last week and that has since disappeared due to a glitch…

so i noticed last week that my lows were not making my heart beat off tune... i thought perhaps i am just getting used to my subs and it was time to upgread today me and my sister went to the store, i was on the way back and i turned it up.. and the low end was there.. but not like it used to be.. to i whipped in behind a big box store and poped my trunk.. and what did i see my subs jumping out of the box at me! i broke, a buncha screws... and there were a buncha screws that pulled out of the wood. its maybe time to build a new box. im very glad that the cone had the tensil pad otherwise im sure it would have rubbed thru no sprider crackage no other sign …

I had been searching the market and looking for a non-fanboy sub that was loud (I mean LOUD) but could fit in with an SQ setup and stumbled across a forum where I was first introduced to Fi. After some deliberation I made the plunge with a fully loaded Fi BL 12 and I could NOT be happier! Customer service via email is on point. Best of all its made in the USA (even by today's standards that doesn't mean much, but if at least one person in the USA put the sticker on it that said "made in USA" thats at least 1 job still in our country ) I digress... this SUB F'n ROCKS! PUT IT IN THE RIGHT ENCLOSURE!

I'm sure this has come up before, but I searched and didn't find anything. I'm designing my box to have 1.3cuft per speaker. What would change if I moved it up to 1.4 or 1.5? would it make much of a difference? Also while I'm here, for the BP power, the website says it "increase power handling from 200-500 Watts depending on the application. 
". In this application, being 1.3cuft sealed, would I be okay giving them 1300w? Thanks for any help.

What is the best amp i could get for the Fi Q at a 2ohm load for about 250 dollars?

So I'm not looking to spend thousands of dollars I was looking at a hifonics bxi 2610d It's a 2600w amp But I'm not sure about hifonics ive had mixed feeling about them. Can anyone help me out?
