i would greatly appreciate it if someone can tell me where i can get a book/manual on how to build enclosures all types

Hey, I'm looking to build a new box strictly for street beating. I'm looking to tune it down to 30 hz. It's going in a Mazda 6 so I don't have excessive room to work with... External dimensions of the box will be 40" wide 27" deep and 17" high (double layer on top). Sub will be facing up as well as the port. I was thinking of putting the sub in the middle of the box, closer to the back of the car, and the port closer to the front of the car facing up. What would be better for music? 3", 4", 5" or 6" port width? Any ideas guys?

scott, i sent you an email earlier today on a sub project im doing. wanted to so if you were up to it. thanks bud! Damon

Curious if anyone wanted to help me out by designing me a box for my 2 18" bl's. i want to build it myself for the experience, but dont trust myself designing a box. Obviously new 2 this, if interested i can give u max dimensions and other info for my 98 tahoe. Im plannin ahead and not ready to build box yet, but just would like to find some1 to help me out. Thnx for the responses.

My SSD15 is coming this Friday hooray! So, I'm starting to plan out my install and i was wondering which way i should face the box. I have an '09 Jeep Liberty (the newer longer boxier model). I'm not able to build a custom box or get a good one made at the moment, so i bought a box that should be within the reccomended size and tuning ranges. Things to consider: Box has port and sub on the same face. Sky slider roof - its like the ultimate sun roof without the whole roof coming off. It slides from the front to the back and bunches up accordian style, so if box is facing up it won't be facing a solid exactly. Box can fit any direction in trunk. Just lookin for some inpu…

Hey guys. Im about to pull the trigger on a 12" SSD. My question before I do is can I reverse mount the sub? The space is kind of tight for the setup im trying to achieve and this would be my best option. Also I have a Diamond Audio amp already on hand. It can push 800rms @ 2 ohm and 1200rms @ 1ohm. Which would be my best option.? I was thinking of getting the 12" Q if it is a better option but was hoping to go with the SSD. Im already pushing 300rms to my DLS comp. up front. from a seperate amp. Im looking for an LSQ setup. Sorry for the winded post and thousand questions. Thanks for your help......

Yes i read the sticky at the top of the page, but i just wanted to see what people thought. I haven't bought anything yet, but what about a hifonics bxi2006d (yeah i know its not sundown or anything), at 1ohm (1800-1900 watts im guessing?), on a bl 18 with p chamfer and flatwind? would that be enough to handle 1800 rms? I know i could turn the amp down, but i wanted some input.

ok so i have a 98' chevy blazer s-10 and im going to make a 10 cuft box but i need to know how much space the brackets and braces will take up and what size MDF should i buy??

I just ordered my 12" Fi Q (w/ bp option) and i could never be more excited for it to come. I'm upgrading from a JL Audio 13TW5, mainly for loudness issues. I have a couple questions however... 1. Will the Q be much louder than the JL? The JL is running 500watts @ 4 now off a Kenwood 9104D amp. The Q will run off the same amp for now, getting 900watts at 2ohms. I'm upgrading cause the JL is shallow, only 13mm excursion and barely moves any air... And I loveeeee SQ subs, but also want pretty loud... 2. Now before you bash on me and tell me I should have gotten a BL instead, I must state that i drive a scion tc, with an open hatch area, which is where the sub will be sittin…

Hi, i have a blown tensil lead on my X 12 and i was wondering if Fi could re cone it or replaced the bad lead. This isnt my first blown lead. Before i replaced them but in removing the dust cap i cut through my cone, so i'd rather send it off to Fi. Does Fi cut off the dust caps for this kind of work? or just recone the sub? If a re cone is needed to repair the sub, is there a recone available???? Thanks!!!

alright so i decided i'm going to build my box sometime this week. i'm having a hard time using box calculators and i don't quite trust my results for some reason. the box is going to get crammed into my 98 corolla. i made a replica box out of cardboard and the box has to be 17" heigh, 20" deep and as wide as needed. the sub is a fully loaded bl 15 and i would like the box to be 4cubic feet tuned at 30hz. can anyone please help me? -phil

Im changing my set up.. i only had my 2 10" Qs for a couple months but they arent loud enough for me anymore. I have an 04 super crew F150 and im taking the center seat out of the back seat and im gonna center console 2 12"s. im gonna try to fit BTLs. id like to keep it a wood enclosure to keep the cost down. Anyone have any ideas for how to get them to fit and have the airspace they need?

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.

I already made one box that was 26x27.5x16 and it didnt fit in the trunk of my 94 accord I dont really have much room to work with I know 26x18x16 will work but is there any possible way I can get it tuned right? I will use aero ports or slot.

My old box designed by chris fishercustoms, for daily pounder. Its 49"w x 26"h x 32.25" d with port facin back 9"w x 23.75"h tuned to 33hz. Everybody that sees it says it is way to big and should only b around 14 to 16 cubes. But fi recommends 8 to 10 cubes each. Anyway it sounded good on everything, but I took it out and tried a 4th order bandpass which was good also. Now I want want my backseat back and thought bout tryin some aero's. Any suggestions on the new box, aero's or stay with slot? Thanks

Hey I'm looking to run two Loaded BL 15s. Will these hold approx. 1700 rms each? for light daily use and some compeition use as well? Also is there a tuning frequency that I can get where they will drop hard and still be loud on about 45 hz tones for comps or do I need to just build two interchangable boxes? What size would you reccomend if I'm driving a Jeep and have a lot of room. This is a crappy first thread I know but I am looking for advice direct from the Fi experts lol.

Hey, I have 2 tc 3hp motors. I know they need to be sent in to be machined to fit the 12 spoke mounting holes. I saw where you posted prices for a 3hp recone, there were prices for a 12/15/18. Can you do a 3hp 10" recone?? The motor measures 7.5 inches wide at the widest point. I'm hoping there won't be a problem with 10's. I'd like to send them this week, but waiting to see what can be done. Thanks FI.

I saw some mj-18 motors for sale and I was wondering if you had recones available for them. I will need 15" baskets aswell. Thanks, Ryan

I'm building a 2.5 cu. ft.box for a BL 12 right now and I'm aware of the recommended port area but I was wondering what the downside to more area(42 inches) would be. Thanks.

I'm trying to figure out the port diameter and length for a box I'm going to build, but every time I use a formula from the internet I get something that doesn't seem reasonable. The box is for a Fi SSD 15. I figured the dimensions are 25x15.5x17 which is 3.81 ft cubed. I'd like the port tuned to 33hz. If anyone could help me out it would be greatly appreciated. And if you could leave the formula for future reference that would also be appreciated....thanks

I love my Sub and plan on purchasing another one but ever since i purchased my 18" SSD back in December i sort of drifted away from the forum and keeping up to date with everything that was going on with FI. I have read different articles saying there are new lines for the BTL and i think BL but not sure on the Q and SSD. Well anyways i plan on purchasing another 18" SSD soon and my first question is, is there a new line of SSD subs and if there is my second question is, will there be a problem if an old SSD is in the same box as a new one.

So, now that my friends vehicle is out of my hair, I have a quick question about mine. I listen to almost pure rap, love it. I love SPL big time, all the vibrations, shaking of the vehicle, etc. Would a 12" ported BTL be the best bet for me? It is obviously going in a car, so room is..well, eh. Or would something like a couple Q's be better in the long run? Right now, I am considering the single BTL. Now this is gonna be a stupid one for ya, which Fi sub compares to RF T1's? I have a dispute that continues now and am curious. Thanks....hope I win this fight, lol.

Dimensions: 41" Wide 33" length 36" heright 2000 explorer. Looking for deep loud bass. Any suggestions would be great.

Hello, I'm new to the forum and would like to say to the Fi section I've done a lot reading here and searching but never really found the answer I'm looking for. I already have a Kicker sx900.2 and looking to get a single 12" SSD. From the research I found so far I've came to the conclusion that getting a SSD 12" with the copper coil option would be my best bet for the kicker? The amp would run bridged, 850 watts @ 4 ohms so would the kicker be a good match for the ssd? If not any help would be appreciated. Just trying to get some feedback before I make my purchase. This will be my first time buying a Fi sub or even listening to one for that matter. I can't wait! thanks…

I am having trouble figuring out the proper dimensions and port area for 2 12inch Q's. I want to have a total of 4 cubes tuned to 32 hz. Any recommendations?
