hi there! im planning to purchase an fi q 12 and fi bl 12. i just want to know the shipping weight and shipping box dimension of these two subs. thaks in advance!!!

Hey i just bought a 15" bl. i was looking around and everyone said a 4cubic box would do but anyone have any cut outs or exact directions. im not sure what i should tune the box to? hertz?? anyone have any suggestions!

need dimensions on a box for a 15 fi sp4. website says 3,5 cu ft but other people are saying go 4 cu ft. really would appricate it

I was wondering if you could possibly give me plans for a ported box for 1 fully loaded BTL 12" dual 1ohm sub. Powered by an Earthquake PHD10000d 3000 watt amp. My trunk dimensions are 36"L x 36"W x 17"H. here is the plans I got off a website. How does this look?

i am building a box for 1 18" btl, going to be about 8 cu.ft. (actual is 8.02409) and tunned to 32 hz. i have done the calculations and does a 10"H X 3.75"W x 7.24"L port sound right?

So I have a 10" Q I'll be running about 1000 rms to. What kind of box dimensions do you recommend. I bought a prefab box for $20 because I figured if it didn't work, oh well I'm out 20 bucks. Well, the Q is a little oversized for the box so I figured, well, might as well just build one. What dimensions should I build it if I plan to run the above mentioned power? Is the .6 cubes best or would it be better to have closer to 1?

hey guys i have a single cab s10..i plan on running a single 10 between the seats inverted. i have came up wit 2.42cft...would 2 4in aero ports be big enough?? the guy i am buying it from said with that little of power i can build a 2.0cft box and gain a lot i plan on porting it out the side...would 3 in from the wall be enough room for the port?? my back wall is 52in. and my box is 49x13x6.5x10...also i am goin to use 1/2 MDF..any suggestions??

i was wondering if any one had any box specifications that they have built, and if you could pass the information along, im needing to build a box to fit in the trunk of my civic, only going to be running one 12 inch driver, and slot port, was wondering and anyone had any dimensions for a box, and port tuned to 32hz. thanks alot im new to this scene, so if i sound like an idiot, just tell me.

Okay so im going with a 12" Q with the BP option and an audioque 1200D amp. I want to port this sub around 33Hz. How big of a box should i make? I know Fi recommends anywhere from 1.8-2.5 cubic feet but what would be the best? Would it be better to go bigger than 2.5 cubic feet or should i just stay around that number? Thanks

im looking for a ported box for the trunk of a 95 caddy, 14"H 14"D 38"W is the max for the box. it's for a 12" ssd how long/big should i make the port to tune it around 33Hz's it also going to be powered by an alpine 650 watt amp.

what kind of enclosure am i looking for? i have a 1995 lumina, and now im seeing what kind of box i should go for. ( i have a very large trunk. ) i think my MTX JH55 is a 4 cube box. and i still have room for a little more, could someone post the exact and best enclosure for the FI BL 15? and is there any very good box builder for xp or vista? also could i get exact specs for the 15bl with cooling, daily, universal, and a red dustcap. ALSO would a hifonics 1200ixd amp wire at 1 ohm be ok to power this amazing sub?

Im ordering a 15 Q soon and am going to start on my box for it. I was messing with re box calculator and having a few problems getting the right size, i have limited space in the trunk of my civic. I am going to run it ported at around 32hz and would like to get as much cubic feet as i can out of my trunk, any help would be appreciated. Box can not be wider than 34 inches, can not be taller than 16 inches, and can not be deeper than 18 inches, any help would be a appreciated. The cubic feet part is easy to me but the whole port part and how long the port should be is confusing to me. thanks Also on the re box calculator site which number do i use to figure out the 12-16 s…

So I just recieved my 15" SSD with copper coil in the mail Thursday. I originally planned to go sealed in about 2cuft, but I have about 3.1cuft after all displacement to play with, so I was thinking about porting it. I wanted the install to be strictly sq, so I was thinking about 28Hz or so. My question is, has anyone here tuned it that low? If so, how's the sound quality? And if no one has, what tuning would you recommend for a sq setup?

I just picked up a 15" SSD and everything else for my system other than the box itself. I have got no idea on the tuning frequencies and port sizes. Can someone help me out. Ive got about 30W X 18H X 116L room in the back of my truck. Would a prefab box sound okay? Thanks in advance

I have the basics for this box already, but I need to know if I need any bracing (if so, what kind) or any other tweaking. Also the sub is facing up, does it matter where I place the sub? (closest to the port opening or furthest away) Box is 24x30x15.5 Port Width is 3.9" Volume a little under 4^3 (after displacement) Tuned a bit above 30hz Thanks

i believe the biggest size i can do is 30x30x14 .. thats about 4cubes.. i made a design on re calc.. http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

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

FI website says 5-10 cubes is the recommendation. i will have 1500w on tap and am wondering, what is the difference between the 5 cube box and the 10 cube box. obviously the 10 cube box will be more efficient etc etc. but im more concerned with whether 5 cubes is really going to be enough for an 18? most people build 8 cube+. biggest i can get is 5.5 to 6 cubes, is that size box really enough? anyone with particular experience with this would be especially welcome.

whats up guys. i need to figure out some dimensions for the btl 18" sub so i can fit it in my 1962 chevy belair. any adice would be greatly appreciated

hey guys i posted a few months ago about half of my port being covered up and basically it isnt much louder and it makes the music sound sloppy so i dont use it i was wondering if anyone could give me tips on a new box that i could build for it to get some more out of the sub box specs: 35" Wide 16 3/4" Deep 27" Long port specs: 25" Long 5 1/4" Wide 16" deep (outwards) 11 3/4" deep (inwards) (port isnt typical L shape) http://s1284.beta.photobucket.com/user/FiAudioUser/media/boxspecs.png.html?sort=3&o=1 (pictures) i drive a station wagon and have a few more inches long/wide to expand if that gives me some more DBs any help guys? ask any questions you…

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?

Hi my name is michael, I am new here and figured this would be best place to get help. I have 2012 fusion, I want to add these 15s I understand the box will have to be built in the trunk and will pretty much take it all up. I will be putting the batteries in the spare tire well. I will be running DC power 270Xp. Min of 2 runs pos/ negative 0 gauge from front to rear and probley the NS-1 amp. I have around 45 inches in length, 18 High, and 25 deep. I have been doing some research and it looks possible and many cars have 2 15s but just trying to get others opinions. I know it gonna be hard but I figured might as well do it right the first time. Thank you for taking time to…

I am going to be building a box for my 2 15" btl fully loaded, I am curious wat of the two would be the best and how big should i cut/make the port, Also let me know if I mite need to make the box a lil bigger. ( i am also using 3/4 inch mdf) And should I have a baffle in between the subs or would one large box be best? Box 1 height 19" width 39.5" depth 23" Box 2 height 16" width 39" depth 35" Any help would be appreciated.

I just bought two 15" SSDs with the copper coil option..I will be giving them 1500 watts.. I have a '95 4-door Blazer they will be going in. My question is, what size box and tuning would be ideal for the best LSQ I can get out of this? I want the subs to be able to get LOW also.. And how much port area?> I am new to multiple sub setups.. Does each 15" need its on chamber? On another note. WOuld I get better results with the subs/port facing back towards the hatdch, or sub up, port back CRX style?
