This is my first box design and I just wanted someone to check over it and make sure it's accurate. It's for a hdc3 18 on a bxi2010 in a 96 Blazer. The box specs are 37.5w, 21.5h, 21.5d, port width is 6", port length is 6", 6 cubes tuned at 36hz.. Thanks.

I need help. I traded my 2 vvx-15 for a sundown v2 18 inch in a box that needs help. I want I box thats tuned between 30-34 htz. I want it vented not ported, I like the look better. I like how loud it gets but I would like to control it a little better when I turn it up, but I think its the box that leaks. I have a jeep grand cherokee, so I know I have the space for a large box. At the moment the the sub faces up I would like it if it fired to the back. Any help is greatly appreciated. And I am still running the planet audio bb2400.1

Hello all, am quite new to this forum and have been around caraudio for a little while but still have a lot to learn especially as I haven't been as passionate as most seem to be here Anyway I have this old car in good shape that I am using to drive to work at the coal mine and have put a stereo into it although most needs to be reinstalled as it is just temporary. I have a 15" RL-p Soundsplinter sub on an SAZ 1500D amp and an alpine HU and some Hertz 165 high power components running on a 400W MA Audio amp I had laying around. The Sub is in a ported enclosure I built a while back for the 08 Charger I had but never put the sub into...... problem is the enclosure is too …

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.

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…

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

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.

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.

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.

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 …

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 need some music in the garage while i work on my car so it's not dead out there... I have spare parts from car audio that i will use, so as u see, nothing in specific like building in the car... I have a 10" sub Audiobahn Eternal wired to sundown 100.4 bridged at 8ohm. Outputting only ~108w on a test tone is PLENTY of power for this 10" sub. It can successfully drop down to 20hz on some custom music i made so i know it's not a bad driver to use for simple music setup. Now, the box i have it in is not suitable.. but i have a problem... The low end extension doesn't become really audible below ~30hz unless i am standing 20ft away from it. How can I get decent low end outp…

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

I was doing a dry build of sub enclosure yesterday and I decided to see how the kreg jig would work on some scraps. I wasn't able to find a bit long enough and small enough to pre drill and the wood split. My question is can I use"L" brackets instead and how good would they work? Second question what sealer to use? I'm not going to be able to seal the top panel because I will have to put my subs in when I put the front baffles on and I will not be able to get to the top inside corners what should I do?

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...

So I just received two of these: Trans Dapt Performance Products - Battery Trays Going to install them tonight however I'm wondering what those clips and second piece is? Also, I'm going to drill into the rear cargo area of my tahoe and bolt those trays down...How do I ensure I'm not drilling into something important? (On the bottom of the truck) Thanks

Me and a buddy are building a box for 3 12 inch w6's, I was curious if I could have them all in the same chamber or if I should divide them all into individual boxes we already have the entire box built excluding the face of the box.. The dimensions are 51 3/4 wide by 16 1/8 tall by the top board is 15 inches deep and the bottom board is 18 7/8 deep (the box will have a slant face)(I am also using 3/4 inch mdf). I would also like to know how big I should build the port I wanna get about 32-33 hertz. Any help would be very much appreciated.

im building a rectangular box. i was gonna ported cuz i was gonna get a 10" fi ssd. originally i was gonna make a L shaped ported box but was told 2 get aero ports insted. the box that i wanna build is 3/4" mdf and is 30" long, 9" deep, and 12" high and has 1.30 cu. ft. of air. The ssd needs to be .90-1.80 cu. ft ported to 33hz. wat should i do? can sum one make a diagram or sumthing? thanks.

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

i have a box all designed on sketch up, 4.2cuft tuned about 30hz. the sub will be on the rear passenger side of the cab, it will take the middle seat and the passenger seat in the rear. the sub will aim inbetween the front two seats and the port will either face towards the roof of the cab all the way to the passenger side or towards the drivers side. what would you guys do? originally i was going to face the port towards the drivers side, but if i have a passenger in the back i think it might blow their ear drum a bit... but i am sceptical about aiming it towards the roof because i dont think ill have as much air moving throughout the cab as evenly? idk.. what would you …

Hey guys im looking to buy a custom box for a Fi Q12 and I was recommended 3.2 @32. I was reading on here that they recommend 1.8-2.5 cubic feet @ 28-33Hz (32 being optimal) Im a little confused, could some clarify what the best box to purchase would be. Cheers!
