SPL & SQ / Fabrication

Info: 2-10" Alpine Type-R's in a sealed enclosure made from 3/4" MDF Volume: .882 ft^3/sub Inside dimensions: 10"x10"x15.25"/sub Outside dimensions: 11"x11"x32" Cut pieces: 2-32"x10" top & bottom 2-32"x11" front (subs will be mounted here) & back 3-10"x10" 2-sides and center divider How does this look? I assumed that 3/4" MDF is like 3/4" plywood in that the actual thickness is 1/2", or am I wrong? Thanks, Ed

I want to mount a Double DIN unit in my 1.5DIN dash opening. Yes, I know it is 1" taller, and I know I need to be doing some modifications. I can handle that. My problem is, the unit I want to use does not come with a cage. http://www.crutchfield.com/S-qehudI3MTzg/c...550&I=257AVX706 So, I need to fabricate a way of installing the Double DIN in the dash without use of a cage. Perhaps I can use an already existing kit... and mold it into my factory stereo trim piece. The whole bezel over the stereo and HVAC controls comes off. And use a kit like this one: http://www.scosche.com/scosche_caraudio.as...&ItemID=HA1566B Mold the kit right to the bezel, then slip it in…

Any advice on doing an external port, like how to attach it and are there any negatives to doing this? Im planning on getting 2 sa-8's and putting them under the back seat of my 03 extended cab 1500. I will have the port coming out the side of the box under the seat as well. I plan on making it so I can remove the port to exchange with others, really just to see the difference and also because of size restictions. Box will be 2 cubes after sub displacement, so I will probably do a 5"x6" port 32.5 inches long for 33hz tuning and another one fro 38 or 40 hz. Thanks for any input guys.

heya... i would like to know how close can a sub(magnet) come the back side .... ..(if the sub is 10" ... can the depth of the box be 16 > or if the sub is 18" ... can the width be 19" ) ...can it effect the sound ..?

today is a little local show..nothing big, again sponsored by stereo one (yay )...so i'm going up to see what i do on a audiocontrol mic let ya know later!! wheeeeeeeeeeeeeeeeeeeeee

Would this be a good box for 2 xcon 12s running a crescendo bc 2000d I'm planning on running it at 2 ohms because I'm hoping to run stock alt with an extra batt. in the rear for now. I was hoping to run sub and port forward sealed from the trunk so my max height is 18 and width is 32 and that's real tight. If someone else has done this I would love to see pics for reference. http://i1257.photobucket.com/albums/ii511/trpkkd/accordbox.png

Thought I would post this little bit of theory that I discussed with Mattdog from Neons.org tonight. I would like to see if anyone has anything to add/discuss further? Typical 4ga stranded copper wire has approximately 0.000292/ft of resistance, so for a typical 20ft run of wire to the trunk, that equals 0.00564 ohms. Pretty much negilible, the fuse will have more resistance . A battery like the Optima Yellow Top runs approximately 0.0028 ohms of resistance. Battery resistance changes with temperature, but in the case of a gel-cell deep cycle, that battery temperature will be more stable than the typical lead-acid during use. Deep cycle batteries also have less resistanc…

Been awhile since Ive been on here but I Just purchased back my 2x 15" SSA Icon subs I first purchased around 11 years ago. I have/ had them in a 7.2 cubic foot box net tuned to 32 and it sounded great on the bass music and rap/ hip hop I used to listen to but not amazingly accurate/ punchy on rock, etc. Im looking to only use one of them in my 2010 Ram 1500. I currently have a 10" JL W7 in a sealed box in the truck and it sounds great and I love it but doesn't quite have the output Id like and planning to put 1 of the Icons in the truck. Im considering either Ported or sealed. I now listen to mainly bands like chainsmokers, club music, alt rock, heavy…

i have a 1991 mustang convertible with a shoe box for a trunk. the dimensions are 10h x 9-11D x 40 width. i've been hearing great things about how the sa 8 is a great spl small woofer and wanted to know if i could really fit more than one into a box with such small max dimensions. i also need amp suggestions to run the one or two i will be getting thanks!

Alright guys, I've had these Bravox 3 ways for a while now. My wife didn't want to tear into the van until the Atlas's had died and they're on the way out. The front passenger mid has been giving the "Death Rattle" from time to time and it's getting worse, so my wife is breaking down and wanting me to begin getting the design, supplies and such together to be ready to make a quick change and build for the new set. That being said, I have some idea's about how I am going to do it, but I wanted to run it by the great minds here and see if there's a better way to go about it. First of all, here's a picture of the inside of the van to give you an idea of what I have to wor…

I'm just looking for some pointers on where I could look for reputable information on designing 2 way passive, 2 way active and (after some practice) eventually 3 way active front stages. Just stuff like, what to keep in mind as far as driver selection, particular features to look for when choosing a certain driver, and how to design passive crossovers. I was daydreaming and hit a roadblock when I realized, what the hell do I even know about a quality front stage? I can't say much at all, other than, deaden, and airseal the speakers. So I feel like it's time to start learning, might even have some applicable tips on hand for when the new truck is ready I'm plannin…

i had a rockford fosgate t1d415 before and ive been messing around with custom boxes for a little while. i didnt know too much about winisd back then. luckily my first box i built for it played very nice and didnt have any port noise. i tuned it around 34hz if i remember correctly. i loved how low it could get down. i played into the lower/mid 20's (i know i was playing a bit lower than the tuning freq) and loved it. this time around im going to design a box for my fi sp4 15. it should be here any day (i hope) and i'd like to be tuned low. heres my current design for it. can you guys let me know if my design is ok. i know the port is a little skinny but it looks like the …

Ok, so my buddy does a real decent job at painting and can do pretty decent job at detailed pictures. So what i wanna know is how can i get this type of painting onto an enclosure. Its made with MDF wood 3/4" thick if that means anything. Now im also trying to figure out how to paint this wood so it will look smooth and as less like wood as possible, which means if that cant be done then the detailed painting may not work. Anyways what i want to know is what can i do to the surface, that wont ruin sound quality, that i can paint primer or whatever onto in order to do this paint job to it? im at a complete stop here so any links or anything will help me out at this point. …

so i think i wanna make some new boxes for my 18" BTL's they sound great in the boxes there in right now but i think i can gain a little more output with some new better made boxes. right now there in a 2000 dodge caravan. the boxes are 8.756 cubes tuned around 32-33hz sub up port up. i have been told by a friend that also runs 2 15" btls in a caravan that sub up port up does not really gain the maximum potential out of the cabin. so i was thinking about making the new boxes sub up port back. what do you guys think about differant setups like sub up port back sub up port side sub back port up which one do yall think would be the best? and can any one explain what port off…

Hey guys. i just purchased a 15" Fi.BL sub and before it gets to my house i was hoping to get a box design built.

I never tried this until about 3 months ago when a friend who had W-6's in his truck awhile back said that JL's tend to hit harder in a Ported Enclosure w/ Polyfill stuffed throughout the enclosure. Does anyone know if this is true or not? I have had my 15's in single Ported Enclosures w/Polyfill for about 2 to 3 months and I'm not positive but I think it might be hittin harder but also I have a PPI amp now running these subs when before I had Phoenix Gold XS2500! That could be why also! What do you Fellas think? I have just picked up another PPI PC2150 tonight about an hour or so ago on my way home from work too! So this is my setup now! 2 15's W-6's ran parallel to one …

I have been running 2 12" zcons for little over a year. 6 cubes 38hz 80cuin of port area. drivers side port all facing into cabin spray foam sealed of family car. trunk build. still have to load kids in back seat. seats fold down. Always been run at 1 ohm. I was using a saz3500v1. when I built that box and tuned it. I recently bought a B2 M1s to run on these subs. 7500w @ 1ohm. with the power increase I was looking for any help with what the new box would require as far as net volume. Looking for help????? suggestions???

1. other than using the 16in per cube rule, how do you guys calculate how much port you need? and is this an accurate calculator? http://www.carstereo.com/help/Articles.cfm?id=31 2. how much port area do you need when using aero ports? same calculation? 3. when using a flared port, how do you calculate the tuning; for example, does the flared part of the port count towards its overall length? always tryin to learn new things here, thanks guys

i got a bigger amp for my 10's and now my back wall of my truck flex's way to much ...it has a knocking sound i can make it stop buy pushing as hard as i can on the consol ...what would be the best way to stiffen the wall...the box is bolted to it but only at the bottom ..i could put some more bolts into the top but im not sure it would end it ...another idea i have is to weld some tubing to the back of the wall inbetween the cab and bed ..well here is the only pic i have to show where the consol meats the wall

Jl audio it's interactive

I started a wall and need to know what to tune the box to... Any help would be greatly appreciated.
