SPL & SQ / Fabrication

Hope this image works. Its a very rough sketch of what I'm planning. It's roughly 2.5 cu. ft after port and before sub volume is removed. Subs firing down, port forward. This is roughly the outside dimensions I have to work with and am open to other sub/port configurations if they make sense. Subs will likely be SA-10s or maybe Gcon 10s. Torres calculator showed 32 hz tuning frequency, but I'm confused why it asks for a port diameter and port dimensions for a slot port?? Any opinions?

Right now my enclosure is 6.5 cubes tuned about 33. Port area is only about 82 . . Was wondering what kind of changes you think I could see by lowering the volume more to increase the port area to cubic foot ratio

i'm new to car audio, but would really like to learn to custom build and fabricate (amongst other things), so i was wondering where i could go to learn to do those things. i know there are tutorials, but i learn better with hands-on experience, so are there any places anyone could suggest. thanks for your suggestions

Right now I have a 2.2cubes @ 32hz with 34.50sq.in. of port area with 1100rms for my daily driver. I want to build a pure spl box and a pure sq box before the winter comes. I have 34inches in width and 13inches in hieght. I need to know the tunning, port area, and cubes for each enclosure. I heard spl enclosures should be small and have alot of port area. I'm not sure what kind of boxes I should build so i'd figure i'd ask here since noone knows the icon better than you guys, Thankz.

okay simple enough for the knowledgable ones, IA's 187 12" subs, port up, subs back, going with 4.5 cubes and tunning at 34hz. using 4" aero ports (4"X17") =how many, how long? the one who answers this will receive good fortune for the rest of his days! thanks chop

I was wondering if anyone has ever seen a port like this? Is it even possible for this thing to opperate properly, it still sounds great, but I'm starting to think that its just the DCON making it sound good.

Alright, I am wanting to wait till i get a new vehicle to do a wall. (Still debating). I'd like to use two fifteens in my trunk, Thinking either AudioQue HDC3's, Fi BL's, or maybe some DC Level 4 XL's. A local shop said sealing a trunk on GM cars sounds like crap; Is this true? This would be the plan for my box Would this cause an audible noise or necessarily sound bad? I know it's install dependent but how do sealed trunks like THORSHAMMER's sound?

Well, a buddy of mine has one of these, it's a single cab, long bed. He just got a new, sweet ass small block 350 in it, sounds mean. But his audio, just makes me want to cry.. Stock 28 year OLD 5x7's in the rear, if what he told me is right, and it has no front speakers, doors or top of dash. Well, I told him I could fabricate him some 6.5's into his doors, there's plenty of space, and I was just wondering how would I do the wiring since it doesn't have any power options in the doors what so ever. So what I'm asking, do I drill a hole into the side of the door near the inside of truck and vise versa and find some rubber grommets or what? Thanks for helping!

is there anyone in the Dallas area that could help me build a box?

So like it says how do you figure out the right measurments for 2 or more round or square port? and im asking because im thinking of doing a dual L port design for a 12" BTL. box will be tuned to 34 hz and will be 2.5 cu ft after displacement. so how do you figure out length and port area for each port? also if you know how ot do the circle ports it would be nice to know that as well. because i might end up going the aero port route.

im currently evaluating a couple of designs for my setup and this is one of them i would love to get as much feedback on this as possible. it will be in a 95 single cab dodge ram.

Im in the process of a biulding a new setup which will consist of a 12in FI BL fully loaded with a Hifonics Brutus BRZ1700.1d. My last setup was a 12in FI Q with a Hifonics HFI1000.1d and i had a box i built myself that was 2.5 ft cubes tuned to 33hz with a 2.5 in slot port width. I had it in a chevy blazer and i could hear the air coming out of the box? How do i limit that noise so it sounds clearer? Vehicle: 2006 Nissan Altima Location:Trunk Space Available:30x18x15 Sub: 12in FI BL Music:Rap and Dubstep Goal: I want it to have the best SQ while doing well with SPL

Do I have a 12 Xcon and I was wondering the best sub an port placement.

Does anyone know of any way to install subs into a chevy avalanche and still have the midgate useable? I use the thing like a truck but still want to get at least a 12 into it. I also have 3 kids so losing a seat is not an option. Help.

Hey guys just need some advice here. I have a 98 Dodge Ram Extended cab and plan to install a BTL 18 in the back. The seat will come out and I have ample room for enclosure. I just want to know if anyone else has done this kind of install in a similar truck and I basically want to know if the FI specs for box will be the best, maybe someone else has found something that works better. I have an Exile X2400.1 that is going to push it. I listen to mainly rap music and I want that sucker to pound. I already performed big 3 upgrade and have cap ready to go, my truck is diesel so I have 2 batteries already. I figured FI's specs for enclosure are on the money just looking to see…

Okay this first pic is the side view. This is in my trunk and it will be set into my wheel well but will also go about 4-5 inchs above that level. My first question is; would firing my woofer into the back of my seats pose any significant problem or reduction in output? Also, can I place my port outside of the box extending into the cabin or would this potentially pose a problem?

Hey all. Im looking for a design for 2 12 Sa's in my PT. My max dimensions are 39 W x 15 D x 20 H. i will be running them off of a saz 3500. Im looking for a cross between daily and burp if there is such a thing. Ive been told in the PT to run port up subs up with slot port inbetween the subs. I had someone making a design with cut sheets flake on me and I have to have a design by Monday when i have a shop to build in. I know this is asking a lot but if anyone can help me out it would be appreciated. the design can be basic as i dont have much room to work with. I just need cut sheet list and I should be set. Tuning should be right around 33-35 hz. and box should be righ…

Ok. I've had 2 12" kicker l7's for a while, but blew one due to shitty setup, and not knowing anything and clipping all the time. Now that I've matured in car audio and have learned to respect the sq and not just bump myself stupid, I decided I wanted to go back and find out what the L7 is actually capable of given the right box. Now is where the trouble starts. I have no idea where to start building a box. I really have no idea how to either. Right now, the two subs are in a prefab dual ported chambered box and that is all I know. One sub is blown too, and I have no idea the tuning. I really want to build a new box. I'm not asking for step by step directions, just some …

I'm almost up and running with 2 sa10's on a sundown saz-1500d @1ohm in my Lincoln. I have a box I built for my Cadillac, that is 2.5 cubes with 40 sq in of port area with a slot port. I'm going to run this for now, down in the well of the trunk. Here's a pic. I want to build a new box that sits on the hump behind the seat. I'm not going to run rear fill or the factory sub. So I will have two 6x9 holes on each side and a sub hole that is 6-8" in the middle. First question is what size aeros to run. Will 2-4" or 1-6" be enough port area? Or maybe 3-4"? Second question, how to port through the rear deck? The box will be 10.5" tall and the bottom of the rear deck is about…

Hi guys im new at this and was wondering if i could get the usual help you guys give others ohh and thanks in advance. I got this system i got two performance teknique amps one is a 2000 watts 2 ch and the other is a 1600 watts one i got two kikker subwoofers 12" double coil 800watts each anda7" lcd screen and an alpine 9851 model radio plus the 7 channel pre amp and the profile crossover ok said that. Now i got everything installed correctly i even bought an extra gel 800 optima battery and a 1.5 capacitor digital now the problem is that of a scale from 1 to 10 i have to have the subwoofers volume down in like 3 cause my subwoofers amp keeps going ofthen have to turn …

first off here is my box: here are the plans i used to build it: 2.26cuft@34hz i have a 12" fi Q BP power off 1200 clean watts and it sounds great in the car but when i pop the trunk while the sub is playing there is this whistling and its really annoying... seems to happen worse on low notes... what is the cause, not enough port area? cuz i am pretty sure there is plenty of port for this sub ive already decided i'm building a new box eventually but this is an annoyance that i would like to avoid with my next build tia!!

Ill have a FI 18 Q here tomarrow , it calls for 6 to 10 cuft box . I have a 94 gmc sonoma ext cab , there will be no back seats . Ill mounts the amps in the back of the seats and one on the roof for the 32 clarion i have ( going in the bed ) . Ive measured out the the box to take up the back 53/23/25 and it comes out to 17 + cuft . What will be the con's or pro's of a box bigger than called for ?

hey guys should i build this or should i just keep it simple i have no experience designing an 4th order and would hate to waist 2 sheets of mdf if some one has input for a better enclosure lol its going to be a 1:2 chamber ratio rear is going to be 1.28 after displacements front is going to be 2.76 cf tuned to 36.09 box peaks at 33.79 at 6.69 db and here are pics of what i imagined

I have a zvx12 and a sk800.1 I need box advice I want to invert it in a 2000 durango, need advice seald or ported what size box do u think I should go with any advice would be great thanks
