I have 4 sa-15s im needing a box for. They will be going in a 98 gmc jimmy. The dimensions I have to work with are 36wx22hx40d. I'd like to do subs up port back. oh and they;ll be on around 2000rms for the time being until i can get a saz3500. Thanks in advance

So basically I'm slowly piecing my system together and had an idea for an amp rack that is somewhat "expandable". It consists of a wooden base, with a wooden box attached to the end of it for the amps, batteries, etc to be placed into. I'm planning on having ventilation and having the rear of it open faced. It would have shelving for the amps.I'm thinking I could secure the wooden base to these strap hooks I have in the rear of my truck (2006 tahoe), have them protude through the bottom then either use a heavy duty strap or bolts through them. I'd rather not drill into the body anymore than I have in order to secure it. One of the reasons I'd like this design is for secur…

Alright so I'm making a box for 2 kenwood 12s. I'm thinking 1.5 for each sub. Idk wether to do a single chamber for both or separate chambers?.. I'm leaning more towards one chamber and one port. I want it tuned to 32 hz. This box is going into a trunk so size isn't a big issue. If anyone could make me a nice design I'd be very greatfull. Thank you.

Just got my new BTL 18 with all the goodies i wanted. now for the box. I plan on building it, but it will be the first one i build. Naturally i have a few questions that i would appreciate anyone taking the time to answer. I got alot of box building info from http://spkrbox1.spaces.live.com/ it seems to be legitimate information, i'm pretty sure i got the link from this site. but should the height of a box really be 1.4X the weight??? with my calculations, to get a box of 8.6 cubes BEFORE port and sub displacement, my box has the be 34 inches tall!!! (25X34X17.5) Ports brings me to my next question... are there are any performance differences in the type of port yo…

ok ,so i got a box (not really square, its a pentagon) made out of 3/4mdf , i got 5.09 cubes of air space with out the sub in (sub its a 15"fi btl) how big of a rectangular port do i need ? its this called port area ?? i had planned to have it 12.5wide x 5tall x 24 long... tuned to 33hz... does this sound rigth ?? please help me out...

i am looking to build a wall in my envoy.... it will be a 4 15 woofer setup and i need a minimum of 16 cubes to make it epic..... what type of port do i need and i would like it to be tuned to about 38 hz but i mainly listen to rap so i am considering 32 hz as well...thank you

I am looking for someone to build me a box for my SSA Xcon 10. Looking for something that will hit on all types of music. The sub will be in a Trailblazer with a cadence A7hc at 1 ohm so around 1200 watts. I would like to keep the size down as much as possible. Ported preferred. If anyone wants to build for me pm me and we can work out a deal. Thanks

alright. ive got the dimensions. i have 2 options of building this. its kind of going to be trial and error until i find the right height i want the desk to be, but here it goes. the box needs to be 4.5 cubes each (2 seperate boxes) and tuning...im guessing like 20ish or 24hz or something? 95% of the time its for rap music. once in a blue moon i may watch a movie on it. but for the most part, i want it to sound best on rap music. the dimensions im working with are 39" x 37" (width and length) using those 2 dimensions, i need to see how high it will be to make 4.5 cubes after determining the tuning and port length, etc. if i like the height, ill build the box using that wi…

I am looking for someone who can design an enclosure for my trunk, max dimms are: H=14", W=38", D=38", Tuned to 30hz, Will be using 7000wrms+. Thanks.

looking to make a sealed enclosure for a 10" Infinity Kappa Perfect DVQ. the sub will be getting 400rms, just trying to get some confirmation on the dimensions of the box i should make based on my reading I should be looking for a box with about .8 cubic feet and using the mid-size insert. this look correct to everyone?

Im about to be doing an enclosure for 2 12" Memphis m5 subwoofers. . And I cant find enclosure recommendations for them.... been looking on google for a while and cant find a straight answer.. anyone know around how big I should make this? I'm going to be trying to get them behind the 3rd row in an escalade. . Dude has not brought it by yet so not sure if ill be able to fit them yet........., ported by the way

Looking to get a decent prefab until I have time to build a box. Anyone have any reccomendations?

I have a 1989 Dodge B250 Van. I removed the backseats and built a platform to hold a setup I am getting ready to build. I will not be building a wall. The subs were going to be facing the back of the van and my plan was to have the port on the back of the box. Do you think that would work properly or should I move it to the front. The speaker box will more than likely 21-24cubes and tuned around 32hz. It is supposed to be for 4 18's or 6 15's. I am leaning towards the 15's.

Ok i have been competing in an 02 ford explorer (third gen) with two 12'' nightshades, 2 1500s, and a big ol battery box in the back.. sub up expernal aero ports back, i am looking at ways to make the vehicle louder not get more power as i am reaching my limitation running in MECA s2, anyone with any suggestions i am at a loss for ideas, also it has the third row seat which make the vehicle about a foot longer than the one without in 3rd gen models..

I am the fortunate owner of a 4th generation camaro :-p Anyways I have a dcon 10 on the way with plans to add a second. Ive seen the box plans for optimal ported and they look fine but because my box is going to be 3 sections with a wedge on top I dont even want to try to do a slot port. If anyone could just give me the size of the box and port ( to achieve the same result as the optimal ported enclosure ) with the port volume already included I would be very thankful

lookin for some competitors who have some experience with 4th orders so i can get a glimpse on starting on my own testing efficiently

Alright I am trying to figure out a design for my car. Box is for 2 15" Nightshades, with tons of power, Jacob said I only need 2.5 cubes per sub. Anyways my dimensions are 30" deep, 16" tall and 31" wide. Only way really to fit this is if I do subs up. Now I wanted to do external aero ports blowing right into the car, but that won't fit. So now I am thinking A. aero ports blowing in but internal, b. aero ports blowing to the side, but internal, c. regular port facing in, d. regular port to the side, e. regular port to the rear.

Currently I have a 15" zcon in a 4th order bp ported through rear deck. Going to be getting 2 12" zcons and trying to think of what kind of box to start on. 4th . 6th. Ported with trunk sealed off? Which ever one I chose I'm going to be porting through my rear deck.. I think I can get about 9 or 10 cubes if I pretty much Max the trunk out .which I could do... Just seeing if anyone has any opinions on anything that will help me make up my mind? If you got any questions just ask. Going to be running 4 - 5k. Maybe a little more. Wanting to get started a.s.a.p. thanks.

I decided to temporarily put in one of my SE12's in at 2ohms on my T3002 in mono mode. Giving it approx. 800 watts. The box is 2 cubes after all displacement. For the port I doulble up a pc of 3/4" MDF and glued a pc of 4" pvc pipe through 1 layer and router a 1/2" radius on the top layer to make a homemade aeroport. The length overall of this port is 13". I don't believe I am right in thinking the tuning is at 32. Can someone double check me on this. Also am thinking about shortening the lenght of the port to get about a 35 hz tuning. This is just a temporary daily box for me to have something till it warms up. But I listen to all kinds of music so I needed some beat in …
