Ok well I am going to be buying a 15 BL here soon and I just found out that the entrance of my trunk is 15" maybe 15.5" so there's no real way to have it facing back how should I set up the box since I can't do it this way? dimensions of trunk are H15" W32" D30"

got my sub couple of days ago and need a design. its going into a 99 cadillac escalade so theres plenty of room... can you guys help?? listen mostly to heavy rock and some rap.

i would like to ask about the best enclouser firing direction for this truck? i have a 4 cb. box tuned to 32 hz. sub and port facing the same same way, but facing it forward it puts the port to close to the back of the seat and firing it up flexs the top unreal! can anyone help me with suggestions on a goob enclouser build for a silverado ext. cab truck with a loaded bl 15 on 1500 watts? music prefrence is rock and rap bass tones... thanks for all suggestions...also i would like for it to be loud and hit hard as possible and keep the enclouser size to around 4 cb. tuned to 32 hz. again thanks...

Hi, sorry to cross post. I just put this in the wrong section the first time... This i what i'm working with: 2006 Dodge Ram 2500 Diesel Quad Cab Big 3 upgraded 2- 15" fi BL 2- kicker zx1000.1 3/4" MDF custom center console box with 5.6 cuft of airspace after sub disp, bracing, and port. Would love to have a bigger box, but space is LIMITED. No divider between subs/ subs share air space Single Slot Port is 15.5" x 3" and 14.75" long (around 32 hz?) Subs will be down firing and port will face up. Definitely SPL Questions: 1- Are the port dimensions correct for a 32 hz tune? I keep getting different measurements depending on the port calc I use. I think carstereo.com…

What do yall think about this http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0 Would you make any changes or is it feasible.

I'm new to the forums and i was interested in purchasing a 15 inch bl and running it in a ported box for loud bass. I'm not into competitions or anything like that i just like loud music. I've been watching videos on youtube and the realm of excursion and i think these subs are badass. Now to my question, if i purchased one fully loaded 15 inch bl how many watts could i put into it and be able to pound everyday in a daily driver without blowing it and which amp or amps would be best for it?

Ive got a sp4 15. Is it possible to switch the basket to an 18.

I'm planning on building a box for my sub, but I cant find the parameters anywhere on Fi's website. does anyone have a link or know what the parameters are?

I was going to put 2-18'' Q's in a ford excursion until I heard ONE 15'' BTL fully loaded in a excursion powered by a hifonics BXi2006. The box was 3.5 cubes net @ 33hz. Let me say that it was loud!!! I want to run 2-18'' BTL's fully loaded on my new TE4001D amp!!! Would 2-15'' BTL's hang with 2-18's? Or will the 18's smoke the 15's like that? I really want the 18's and if I put each one in 5 cubes @32hz what will happen to my excursion?(Each sub will see about 1800 watts each.) If I use 5 cubes or 8 cubes per sub what would it do to the sound of the box? I want my X to fall apart from all the bass and I want it to be LOUD. What would the Fi Audio Guru's do...

I was planning on getting a 15" ssd for my 95 saturn sl2....the problm is my trunk isnt the biggest. I have enough room to make it the recommended 3-4 cubic foot box but i would have to face the sub towards the top of my trunk. If i did this would it still sound as good as if it was facing the back of the trunk, and where would I have my port facing. Can anyone possibly make me a box design that would fit in my trunk for the 15" SSD. the trunk is about 15" tall, wheel well to wheel well is about 35" and back to front im not to sure. I would greatl appreciate some help on this. I was also planning on running my Us amps xt2000D on it.

Site says the cutout is 14.125 what does that equal out to? I have a router jig, is it like 14 1/16? Or 14 1/8?

Hey guys! as of a few hours ago, i ordered a 15" BL and a Sundown SAZ-1000d amp! I was just wondering how you guys think this will sound! and suggestions on my box. I want to make it ported offcourse

I'm in the process of buying a 15" BL within the next two weeks. i was going to pay someone to build me a box, but its going to cost +$200 and take well over 3 weeks for him to build it. so i decided to do some some research (and save some $$$$) and found two enclosure plans that fit the 15" what one should i build? the first design or this one Net volume: 3.5cuft Tuning: 33Hz Port Area: 52.5(15"Hx3.5"W) Dimensions:16.5H"X24D"x26.5W" *design stolen from ROE. Another question, Its a fully loaded 15" Bl powered by a rockford fosgate T1500-1BD the amp is rated at 1000W x 1 @ 2-Ohms RMS 1500W x 1 @ 1-Ohm RMS is it safe to wire the subwoofer at 1ohm for daily play? i know…

I found these specs ~4 cuft net tuned to 32 Hz 16" h x 40" w x 20" d Port is 14.5" x 4", 30" long. To get 30", you make the side port wall so it extends into the box until it is 4" from the back wall, then add a piece 10" long running parallel to the back wall. Box is .75" thick, except the baffle is 1.5" thick. I made this in sketch up to specs I wanted to see if it looked right. besides the port being off the ground i think it is. I am new to building sub woofer boxes so any help is appreciated

Will 15" BTL's work in a ported box for DD 9515 subs. Port area is 165" per sub and port is 9" deep. This is what I was told to use for the DD subs. This is a SPL set up only. I know this is more than FI recomends for port area. Total box area is about 17-18 cubic feet.

Im running a T20001bd to each fully loaded BTL.. how much output would I lose if i ran each sub in 3.5 NET compared to 5 net.? Tuned to about 32hz..

I want another t-line in my truck. I had a dd 9515g, it didn't hold up. I will have 3kw on hand. What options on the 08 model BTL would get where i want to be with suspension, cooling, and power handling, as well as x max........If a combination of stiff spiders was needed then that would be ok as well. I just don't really know how well they will handle this type of application. It a 2006 nissan frontier(the big ones) xtra cab so i have a decent amount of room as my backseats are removed. advice will be appreciated. Jason

I have a 2004 F150 super crew. I dont want a blow through and I am thinking about taking out the middle rear seat and putting a center consoled 15" there. I currently have 2 10" Qs under the back seat but I wanna go louder so I need someone to help me design something width needs to be 17" - 17 1/2". and height there is plenty of room id like to keep it under 30" and there is enough depth for 30". Iv been messing around on the rockford boxwizard and im looking at possibly a wedge type design with a flat on the back top of the box with aero ports and then the front facing sub.

Alright, im kind of tossing the idea around between two setups in the trunk of my Crown Vic. Setup one is (1) FI BTL N2 18" in 7 cubic feet net tuned to 32hz. Setup two is (2) FI BTL N2 15s in 8 cubic feet net tuned to 32hz. Here is my problem and question, the first setup with the single BTL will slide right in my trunk with no issues using the box design and cut sheet posted on this forum for it, but the second setup is the issue. Can I run the BTL 15s in a smaller box than 4 cubic feet net each and still get optimal performance? Id like to shrink the box and bump up the tuning to 34-35hz if thats possible. 3 to 3.5 cubic feet per sub would be a much easier fit for …

I have just purchased 2 15" BTL Fully loaded. They are on 2 mmats 2100.1. I just got them and they SLAM!!!!! I am seriously and deleriously happy BUT I know I could be happier. My box is very small for these subs and I drive a big car (Crown Vic) so I know a new box is a good idea. My current box dimensions are 48" Width 17" Height 17" Depth, measured OD......Port is 4.5" wide divided with .5" 15" deep 15" height, measured ID. This car is CLEAN CLEAN so with that in mind I don't want to go tearing it apart...totally. I dont mind ripping out the metal behind the seat or cutting the rear deck. Here is my goal: I want this system to BANG and does already but my trunk sounds…

Guys, I know the BTL enclosure recommendation for the 15" BTL is 3-5 cubes net, however I also know that required volume is also dependent on power supplied. I was wanting to know if there would be any problems with running (3) 15" BTL's in a 8 cube net shared chamber enclosure? I should have roughly 3500 watts on tap for each sub, but I will not submit them to that much power, I was just wondering what I could get away with in terms of enclosure size? This is a daily beater.

n00b to the forum that is , did this one for a local guy. I'll let the pictures do the talking. It was a little dirty sorry, I had to snap pictures off quick and vaccumed when the guy picked it up. Comments welcome, I've got a few other BTL enclosures I've done I'll toss them up as well otherwise check out my photobucket page HERE

Is this too big of a "enclosure and port" for a daily. For 2 fully loaded BTL15 with a T4k ......11.1ft3 (net) with 160sq" of shared port tuned to 30hz....after sub and port displacement subtracted I got a total of 8.6ft3 which would be 4.3ft3 and 80sq" of port per sub. Is that too big?

Hey guys, my enclosure is nearly finished. The specs are.... It's 3.97 cubes before displacement, so I am guessing around 3.5 after due to the sub displacement and the bracing. The box is tuned around 33hz. I've tryed it in my friends vehicle and it pounds pretty hard. Not 100% happy yet. I'm thinking that's just because it's not broken in yet. I heard it in a Ford Expedtion, but the sub will be going in a 96 Cutlass Supreme. Hopefully it will get much louder. I'm powering it with a JL 1000/1. But what I'm wanting to know is are those good specs for the box? That's about the biggest box I could fit in the trunk. Help would be appreciated!

Hey, just received my 15" Fi BL and just constructed a box for it. Box specs: Port Area - 55 Volume before displacement - 3.97 Frequency - 32.2hz - 32.6hz Setup: 15" Fi BL Jl 1000/1 2 awg wiring Stock deck Stock Electrical Here's the problem. My freind with a 12w7 in an H/O box kicks this subs ass! His Setup: 12w7 in H/O box Alpine PDX 1000.1 4 awg wiring Alpine deck Stock electrical His system is in a Dodge Magnum mine is a Ford Expedition soon to be a 96 Cutlass. My plans: Kinetik HC 1800 or more Non stock deck Big 3 under hood Maybe new ALt What else do I need to make it pound harder? New amp? Is the box good specs? Help would be amazing!!!!!!
