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 have a DC Level 4 18 m2 on the way and i want to make the box before ite gets here (cuz im so impatient) going in a 99 grand cherokee listen to all types of music but i do like playing down to like 27 hz or so powered by an american bass HD 3500 (1600rms) id like double baffles max dim are 40 wide 30 deep and 20 tall i think that about covers what is needed. any help would be awesome! thanks guys

I'm helping a friend build a box. I've done a few boxes in the past, but this one is different. This one isn't a rectangular box. He wants to, or needs to, use all of his trunk space to squeeze in 2 15" Kicker L7s. The box I designed is 6.11 cubic feet after displacement tuned to 33 hz with ~78 square inches of port. It will be braced and double baffled with 3/4" MDF. My only worry is the port being cut off by the roof of the trunk, but it's got a couple inches to breathe, so it should be fine, right? Criticism is welcome! Thanks!

Have this started on a couple other sites. Been out for awile (5-6yrs). Wanting to get back into comps. I already have 6 MA HK4000ds and a VW Golf hatchback. Also have a buddy selling a couple Americanbass VFL400.1s for a good price. Would prefer to stick with the MAs because I have them. Looking to do 2-15s in a wall. Prefer the street class to save $$$. Have about $3500 to spend. Also what would be some good sub options. I used to run some Apxx's and have seen several motors forsale. Also the RDs I have seen do really well.

I need help with a box spec for my 2 Sundown Audio SA-15s. Its going into a Izusu Rodeo. The box can be up to 41 inches wide. I looking for a box that i can use as a daily driver and for competitions. I would appreciate the help.

So I keep getting told that an active front stage can be and usually is better than a passive component setup. Now, doing the front stage is very new to me. I've really only done a co-axial set powered by a 2 channel amp. I'm going to need some help with speaker selection and ways/tricks to make sure everything is installed/tuned correctly. To put a number on a budget, I would say $400. That number is just what I have set aside for the front stage currently. Sound deadening is not included with that budget. This is going into a 2014 Fusion. I don't want to cut any holes in panels and I can't fiberglass so stock locations will be used. Which is a 6.5 and tweeter. I will b…

I have two 10 inch subwoofer in a very big box. 4.4 cubic feet before displacement. I have one 4 inch Aero I made with pvc pipe but I get noise at low notes,tuning right now is 30hz. Was thinking to go with 6 inch tuned to 33hz.

Hello, I am building a box for a friend and I had my MDF all ready to cut, measured out panels and everything and he calls and tells me that he want an aeroported box. I have searched and read different things in this section and after figuring out slot is actually a lot more different than aero ported, I just don't get it. So, I have come for some box designing help. Dimensions: Depth: 16 Height: 16 Width: 40 It is for an Fi X 12. Was hoping for 2.0ft^3 at 32hz I really just need to know how many flared aeroports I would need with no port noise. Diameter and Length of the aeroport would be nice. Thanks in advanced, Jay

So I've modeled my Crystal cmpx2 12" and it is completely flat from 30Hz + in a 2.1 cubic foot box tuned to 22.8 Hz. That's perfect but I'm having a hell of a time putting it together. I have my max dimensions but I'm stuck. It's a slanted box in the back. Can someone put something together so that I can get this built asap? Height can definitely go down, and width can definitely be made smaller, but I'd rather it be wide over tall just to look symmetrical. I dunno why but I'm insanely anal about symmetry. 40"w x 18" tall x (9 1/4" d1 /// 14" d2)

Hi I need some help designing a box for two Digital Designs 2512c D2 Each sub will be wired to its own hifonics brz1200d @ 1ohm My max dimensions are: 38W X 14H X 22D I am looking for subs+ port (centered) firing foward I listen to rap Thanks! p.s- i plan on printing what i get here and giving that to a shop (cut list, google sketch ect.) i dont have the right tools to do it myself

Hey guys. I just picked up a new RE SX 15. Its going to be powered by a Sundown 1500D in a '08 Scion xB. I need help designing the box though. RE calls for 3 cu ft minimum, 4 cu ft optimal, and I would like to tune for 32Hz, sub firing up. The sub displaces 0.18 cu ft. The dimensions I have to build the box are 38.5"x18.5"x19". The pictures below should help to visualize. If there is too much space there, I'd like to cut a couple inches off the height, and then if still too much room, a couple off the width (18.5"). Help needed! ~Trevor

I am building a box for 2 SA-12's for the trunk of my altima. I want to have a square port between the 2 subs on the front of the box, looking somewhat like this: O | O sub port sub Using 3/4" MDF and outside dimensions, my box's height can only have ~ a height of 16.5", a width of 33", and a depth of 16.5" (however, the depth can be altered a good bit if needed) I need to know what dimensions to make the port and the dimensions of the box itself if anyone could help. Thanks.

this will be going in a '06 gmc ext. cab 4 door.im not walling it. 2 21" DP's.ill log everything and put it up on here as well as ROE maybe even Classifiedzz.but i need to work some kinks out of it first DP 21

hey i wanna enter iasca rookie competition but the sub im using is a 15" atomic apspl15, in the category im only allowed 1 4" aero port, what size box should i use and what length port, the car is a mazda protege5, right hand drive cause im from trinidad, the amount of power is 1500 watts, the box will have to make high spl while playing music since in this category you are only allowed to test with music

My buddy is trying to put a 18" fi ssd fully loaded in the back of his eagle summit van.. He has about 1200 watt rms of power to run the sub.. There is two different set of max dimensions we can use ( it all depends on how tall the box will actually be. The first set is a tall narrow box and our max dimensions are 27 1/4 tall X 39 wide X 15 Deep. And the other set is 20 1/2 deep X 39 wide X 21 tall. Any help would be wonderful... Would really like start build on box as soon as we can.. Also I would like it ported wit a tune right around 32 hz. And I not sure wat would sound best wit the speaker direction and port direction so any advice is wonderful.

I need help with a box spec for my 2 Sundown Audio SA-15s. Its going into a Izusu Rodeo. My goal is to hit over 150db. The box needs to be 6 to 8 cubic feet, port tuned to 35hz and max width is 41". I looking for a box that i can use as a daily driver and for competitions. I would appreciate the help.

i bought a rockford fosgate t1500bd amp and it says its subsonic filter is at 28hz. im buying an Xcon 15 wich says to tune (optimal) 27-34hz going to try putting it in the optimal box size of 4 cubes. ive heard that 33hz is the best tuning frequency all around. i listen to all types of music and i want more sq than spl. also heard that your supposed to tune the box about 2hz higher than the subsonic filter. (gives me tuning of 30hz) is that true? why or why not? what should i tune my box to?

I got a cut sheet from skar audio, and i want to know others opinions on it. Ive tried to draw it up on paper to visualize, and ive done some calculations to help someone who knows how to use the info. Its for a friend so i don't wanna waste his cash on a shit design. Ok so he has a 97 Jeep grand cherokee. 90a alternator, I did the big 3 for him in some 4 gauge stinger pro i had laying around, and he had already bought a Rockford amp kit 4 gauge also...pretty nice wire. Ok the max dims are 36" wide, 36"deep and 30"tall, this leaves plenty space for the port to breath either up our back..The subwoofer is a skar audio ivx15 V1. Its a d2 coil. Here's spec off woofersetc.co…
