CRX defies spl physics bud. you can fart and probably pull off a 140

Lol i could.....but I always seem to fry the coils when i give my subs more than rated power even if i use a multi meter and my oscope....i dont understand how people can give a 1500 rms sub 3000 watts daily and not fry the coils. How do you get the mounting holes on the baffle to line up on all the layers? I have a jasper jig but my cutting bit is only long enough for one sheet at a time. Ok I'll do two layers on the back, and i can switch the 2x4's and make them vertical. And yes i have no clue how much pressure they'll output ha. But im very eager to find out. Ive sat in a crx with two team rockford 15's and four memphis 2500's and it did 155 legal sealed

After you cut the holes you'll mount the next sheet in place and use a flush trim bit in your router to make the pieces identical.

Check the way we used 2x4 in this one http://www.caraudio.com/forums/car-audio-build-logs-cars-trucks-suvs/621757-civic-wall-build-shocker-jbl.html Port was very problematic on this. Sounded great, never really got any good numbers.

I forgot who else used 2x4s for an entire she'll then placed 3/4 plywood on the inside and it came out pretty strong with no need for double baffles all around.

Alex used 2x4 and no sheets, IIRC he tore that one down in a week or two.

Ok thank you hispls and tymoto.... I needed some guidance as far as what i need to do next...do you think if i used just 2x4's anr filled in the gaps with glue it would be just as strong as two layers of plywood? Because it's really hard to bend a 2x4 as opposed to a sheet of wood. Plastidip is easier to paint on than tinting the windows and its darker because its paint and not film...and no my amp is the 1 ohm version. And i know not to run it under 1 ohm, i made sure i did my research on that lol.... here's what i have done so far.....

Those 2x4 are the wrong way. They will flex and bend like that. I don't think u understand how much pressure three 18s will produce. You need to go into the build log section and look at 50 build logs and see what other people did because that 2x4 picture is going to fail

Gotcha hertz mafia and hispls... I will definitely change the 2x4's. Thank you for letting me know that. Also should I have them going vertical flat or vertical like studs in a normal wall in a house? Your absolutely right hertz mafia, I honestly don't know how much pressure they will produce, but I'm very eager to find out! lol. And I've always had the worst luck using a flush trim bit. I have no clue why. But everytime I use one I always f uck something up. It never fails. Is there another way to get them to line up right? I will update you guys here shortly with some pictures! Thank you again to all of you for taking the time to assist me in my build! I truly appreciate all the help! You have no idea. Because I would be lost without you guys lol. That's for sure! Oh and hertz mafia do you by chance have a picture of the inside of your wall? Cause i've seen your's in your sig and it looks amazing on the front!

Wow! I really like that! Would you recommend that I do the 2x4's like that instead of vertical? Cause that's definitely not a problem.

Either way should be fine

I would stack them the thin way

It seems you don't have very much cf and if you take 3" + a layer of ply you will quickly see your 15cf wall turn into 10cf

It is much better to do it that way though

Thin way meaning what? Like the picture the OP posted? Because that way is wrong and will flex bad. Pointless to do it that way.

 

[ferguson621]

Lol he means thin as in how the studs are on a wall in your house.

 

[YukonXL04]

When routing multiple holes that need to line up, stack the layers your want to make holes in so all the edges line up. Then still your center hole through all the layers. The center hole is your pivot point for your circle jig. Then you can router each layer separately and as long as you don't change your router setup then each hole will line up.

Log cabin lol I bet that stiff though ! looks good

Laying down or standing up is still the same thickness so I don't think that's what he ment because it would be taking up the same space. The picture u posted I think is what he was talking about taking up less space because your using the 2" side and not the 4" side. Which is wrong lol.

Progress....

I wish you luck

2 layers braced would be fine.

Do 2 instead of 3. 5 cubes isn't enough for an 18 unless your qes is .3 and fs is in the low 20s.
