FI BL 12" BOX DESIGN
Tuesday, November 04, 2008 8:45 PM
HI i have posted this before (I know im a post whore) but it was under a different name very unclear name that had nothing to do with bl. this post i sort of a question post but basically for anyone that wants to build a box for the FI BL 12.

Well it started with this post
Topic About MTX 9500

Then I decided to go with the Fi Bl (thanks to SLOCAV) he then told me to check out SSA where i asked about the box build.
SSA, FI BL BOX BUILD

well as it stands right now i am still undecided on how i am going to build the box. I got some information from some one that i had contacted through Yahoo Answers and verified his info through a couple of Sub woofer box calculator and he had good advice. the next link is to a PDF of the DWG that is (as of right now) the box i will be building.
PDF OF BOX

Now My question to any of you that has anything to say about the design of the box is that im wondering if there is anything wrong with its design? If you notice even the smallest little thing please tell me. I want to be 100% sure that this box will work for that application before i start the construction.

Thank you,

Anton Miller

I would think that is a good design.
Did you get info on how long the port should be?
I didn't double baffle my plate, but then again mine is hatchback style.

now only thing i wonder is. Which direction to fire the sub/port. I would think port and sub back would be the best, but I'd ask.

In a regular trunk box, that is going to be best results, to have it facing back. In some posts you act like you know a lot, in some you act all unsure about simple things......

Don't know if you were talking about Me or Anton, but yes I do know certain things, but I started getting into car audio a little bit over a year ago. So I am still learning some things.

yea im in the same boat as slocav on that (if you were talking about me) i know certain things pretty well but in the things im lacking i ask questions and when i dont get a straight answer i ask again, and again, and again untill i get a straight answer. sorry if some things get repetitive but i think i have the box building down about now. lol

No, I was talking about Slocav, but at any rate, I hope youactualy find a setup that works for you. Seems like you have spent more time trying to decide than anything lol.

ah yes, sorry if I do seem newb on some topics, but we all started somewhere right?
Anyways
I'm happy to see you ordered the BL, exicted to see what carnage it does haha. It took about a week and a half to get my sub, from order to my door. Really isn't a break in period from what I hear, Just have at it, it will loosen up after a few days of playing, and gets quite a bit louder.



Re: FI BL 12" BOX DESIGN
Wednesday, November 05, 2008 6:14 PM
yea there will always be a break in period yours probly was just normal playing levels because of the 500 rms but i am going to turn the amp down to about 1/3 gain and have the bass nob the same for about a week then ill start giving her some juice. (cant afford to blow a 270$ sub)

Again Thank you for all your help

alright, it is just I have heard mixed things on the SSA about break in, as it will just break in overtime, rather than taking it easy. But hell, I don't want to look like a newb and get my ass chewed for it now. Anyways, gain isn't a volume knob, you know right? Have it set for the preout voltage of the deck.
I more exicted to see how this sounds and what it does to your car, I know mine isn't even getting touched right now...and it is at 450-500w MAX not rms haha.

well the box is built and in my car and it makes a huge difference with just my crappy old fubar in it. i cant wait to see what kind of damage it does with the fi in it. Thanks for everything.

and for clarification on the print i screwed up on the hz call out it was supposed to 34 not 32.

alright, glad you like it.
I'm only getting 450w max on mine and it flexs like crazy.
scratch getting a cap....they are pretty much useless and can do more harm than good from what I hear. Upgrade the big 3 to 1/0 gauge and see where you are from there, then probably a battery or cell in back.



Re: FI BL 12" BOX D
Friday, November 21, 2008 3:17 PM
well i allready have the cap so im gunna put it in and do the big three next weekend. its a 4 farad so basically like another battery back there. just need some help with the lows my lights dim allot! and i bought a new camera today so im going to take a video sumtime this week end if i can find a good enough spot to do it.

yea its really dirty but heres what it looks like. i want to put the amp on the box between the sub and port on the front plate i think it will look ood. but like i stated before it freezing outside or it would be done. so if i want to do it i have to bring the setup inside and my shop is 200 miles away.

and every thing need to be cleaned up (wires and the whole trunk in general.
