The do's and dont''s of my first wall....it seems like something isn't right....

[ferguson621]

Ok I'll do some testing before i tear it down, and seal it off

 

[Lbetts818]

Good idea. I'm surprised you haven't even just said f car Audio at this point lol

2 layers is NOT adequate. Possibly on the top piece since it is so small, but you'll want 3 on bottom and sides and 4 on the back and 6 on the baffle. Once you are ready to build the baffle ONLY cut the first sheet and dry-fit it in place, post pics, take measurements and post here so we can give you some input on how it looks before you cut and glue another 5 layers. Once the top, bottom, sides, and back are on you'll have a much better idea of how much volume/area you have to work with and how to finish the baffle.
It is looking much better though.

Shocker Mike has done a fair bit of SPL testing with particle board. Assuming adequate bracing/thickness WITH RESIN it will perform identical to MDF with resin, without resin is is going to be over 1dB down.

You will definitely want to plan on coating it with resin (and it will soak it in pretty well by all accounts). Consider doing the top bottom sides and back BEFORE you put up the baffle. Call US Composites for some cheap resin and use a 6" hot dog roller to apply. Have Acetone handy and work in small batches.

You need more layers! Rigid and airtight. 2 layers is going to flex terribly. 3 on the sides top and bottom should be sufficient, use no fewer than 4 on the back and 6 for the baffle (when it comes time). If the wood is free your only cost is a few bucks worth of glue and screws. Internal bracing may cause unwanted turbulence and will certainly make it more difficult for you to climb in the box and wire speakers, seal, paint, etc. I'd much prefer going thick on all walls than skimping out and trying to put a band-aid on it later by turning it into a spider-web of bracing. If you find you still have to brace later, so be it, but you should shoot for having enough strength without. Also, no need for those 2X4s in the corners if you're fitting those pieces snug and planning to resin. It looks rather haphazard. One of the things I most dislike about mine is that I had to use them around the back, but I'm compromising there in order to have the back open up so I can use it for cargo space when needed.

Ignore papermaker. He can't even type a coherent sentence and has yet to post any actual real world builds or results of any consequence.

Ok so I got everything done, including the front baffle. I accidentally made the port to long because I wasn't thinking about the baffle being so thick lol.....so I have to cut the port piece down tomorrow. This fu cking box is a god dammn tank! I haven't drove my car yet lol. But I bet It's going to be a huge increase in weight. I'll find out tomorrow. And I plan on taking a few pictures tomorrow during the day so you can see the outcome. I'm extremely pleased with how it turned out for sure! Thank you hispls for helping me through this again lol. I truly appreciate all your help! Do you think i should tune to the subs fs which is 33hz or do you recommend I tune a little higher like 36 or 38? I prefer the high's more. But I figured I'd ask before I cut it lol.

Accordong to that pic of box calc u have them in like 8.7 cubes with way to much port. Should be like 14cubes with less port forsure... u need a good box design

This thread would have been 100x better if he swallowed his pride and paid for a proper box design then learn from it then whatever he's doing now.

We all learn sometime. Some sooner then others. People think car audio is easy and it's not. U really gotta know your Shlt

I tried contacting joe x on smd but it says he doesn't accept messages. I tried contacting ram designs and it says they're not accepting designs at the moment because they have to many requests right now. And I guess cscstang isnt doing designs at the moment. I didn't know of anyone else to try and contact for a design. And I thought you go by gross? That's what i've always been told. I posted a thread on smd requesting for a good design. So hopefully someone that know's there shhit will contact me

On caco sonic does designs for $25

BHE does designs I think

Prly can google it and have tons of people pop up

Your inputting data wrong on the calc. It says you have 3 baffles 3" thick each... So your way messed up on that. Also your box height is 34, and port height is 33.25... so your off there too. Also says your port board is 2" thick. Which may actually be right. Fix that and see where you fall and go from there

Take a tape measure to the box and send me the dimensions. As well as thickness of each wall. Same with the port and I will run it through the calc and see what's going on....

Or measure the inside dimensions and give me that. Plus the port dimensions.

damnn I was way off....I misunderstood torres then lol. Now that I sit here and think about it. I was thinking that the 2 inches meant overall....not each piece, fucck I feel like a retard lmao. Ok well my outer dimensions are 42 wide x 36 tall x 28 deep and the port is 33.25 tall x 20 deep x 5 wide.....the sides and bottom are three layers, and the front and back are four layers, and the top is two layers, the port is also three layers.....and thank you hertz mafia for the info, very much appreciated, I'll message them and see if I get a reply!

And out comes the sawzall again.

Could always donate to the feedafatkid foundation. In the market for some subs //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif teasing man. But for real your making this soooooooooo much harder than this needs to be. STOP trying to build a wall in a day!!!!

 

[ferguson621]

I'll never say f car audio lol. I don't cope well without it haha....I tore the front and top off....I'm going to redo the baffle so all three will fit. I tried getting in contact with those people but I didn't have any luck as usual.

Hunter martin on FB. He did my 6h order wall design.. I'm pretty sure i commented that WAY back earlier in the thread.

How much space did u figure out u had after you typed in the number correctly?
