    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. …

    Alright, so I'm planning a build for my S10 reg cab, and need help designing the box. It's going to be 2 SA-10's in a 2 cu. ft box net, ported, tuned to 33-35 Hz. Also powered by a SAZ-1500. My max dimensions are 50"L, 22"H, 9"D bottom, 5"D top. I made up a box using the torres box calculator, but I was having problems with the port. I'm planning on using aeroports, but they were needing to be too long for that tuning in a small box. Not sure what diameter, and how many I would need. If anyone can help me out I'd appreciate it!

    Hey guys, I just finished my box. Was all excited, i did i dry build first. just screw it in before glueing. After I built the box I take it outside only to find it doesnt wanna go in my car. YES I did measure twice and cut once, but i failed to measure the clearing distance of my trunk to slide it in. Here is the plan I went by 4cuft. at 35Hz Is there any way I can sacrifice any depth when putting this in my car? Height: 17" Width: 39" Depth: 16.25" Thanks for the input and flaming, Curt

    well i was expecting a db drag. and i get there and there is like 4 judges that sat in the car to judge on overall sound. they said that my rl-p's were by far the best subs they've ever heard!!! needless to say i took first place and a $500 gift certificate to extreme motorsports. i was really wanting cash, cause i don't wanna spend any money on my car so i'll probably just end up selling it.... but either way i took first

Also, feel free to use this design and enjoy!!! BOX HEIGHT IS 260mm, 224mm are Internal Dimensions as all pieces join to TOP/BOTTOM ------------ --------- Also I designed this for a 8" Rockford Fosgate P2D28 sub w/ a bit of extra port area for sub upgrades that may have up to 13mm in XMAX such as say a DD sub (P2D28 has 9.5mm)

    This is my first go at trying to design a ported box so just want to make sure I got the numbers right. This is for a coworker. The sub is a DD 9515. According to their site it should be 3 cu with 48"^2 of port. Here's what I came up with: 24" x 22" x 15" and the port 3 9/16" x 13 1/2". If I follow the "rules" and make it 20" long it'll be 38ish tune. I appreciate any input you can give. 15" height is to keep it under the window line and cannot be modified. Other than that any suggestions welcome!

    Hi, A friend of mine who owns an Xcon15 has just built a new box for its baby monster sub. The old one was 3.5 cu ft at 32 Hz, and the new one is 3.7 cu ft at 32 Hz too. Not much more volume, the double baffle upside took quite a bit of what we expected. The new box has a kerf slot port : it's really beautiful, and was easy to do wit the design provided by Dylan. First try : got it !!! I will post pics tomorrow. Just wanted to say that the sound is different now. Don't know how to say it but it gives more low notes. We did not expect so much change!! And we love it!!! The owner had a processor(or active filter, I don't know exactly), he took it off. He turned the bass boo…

  14. I recently brought a pair of LvL 4 with LvL 5 coils to go with my single Autotek MM4000.1D amp. I want to put these subs in an 07 Chevy Suburban LT.The idea is to keep my third row seats. That was the main reason why I brought a suburban instead of a tahoe. So far this is what I've came up with. *Note all measurements are external* Height: 23 3/8 inches or 28 1/2 inches if I go up to top of headrest Width: 49 inches Depth: 28 3/4 inches I went to 12volt.com to use their volume calculator and it came out to roughly 15 cft of internal volume space. I want to go ported with the 18's and I want to go both subs and ports facing up as apposed to subs up and ports to the rear. …

I am very curious to hear what you have to say about this, being that its from ebay. But 4.0 CU. Ft. tuned to 32 hz seem perfect. I know building one will be a little cheaper but it probably wont come out as nice and would save me the headache of building one myself. But if you recommended that I just build one myself then thats what ill do.

  17. 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…

Looking for the most optimal enclosure size using what ever type of port that would work better for me (slot, aero, or pvc port that sticks out of the enclosure itself) with the dimensions I have H x W x D 13" x 28" x 17" tuned to 32hz. Thanks for the help.

    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

    I've always designed the box with the port on the side, but now I need it in the middle (using 2 subs). I do know that when the port splits off the port width gets halved, but is the whole length of the port mean that each side is the port length? Let's say I have a box that is 6" wide and 30" long. When it splits off each side will have a width of 3", but does each side equal 30" long? Someone also told me that you add half of the width of the port to each side of the port length. So each length would actually be 33" long. I don't know why that would work though. When I design boxes I use torres and there's a box that says "# of common port walls". I put 2 in there, …

  25. 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…
