That'll do... The layered idea can be tricky, tho... If the entire layers are not firmly and completely glued together, you can get buzzing... better to go with one inch MDF... I did with mine. My box is about 14 inches on a side internally, and there is NO point in the box with an unbraced panel more than 4 inches square... (every dimension is divided into thirds by a brace U-D, F-B, S-S) The thing weighs about 40 pounds without the driver even in it... Don't use silicone or liquid nails... GORILLA GLUE is the ticket, because it foams up, and soaks into the wood and makes the bond even stronger. Liquid nails can come apart, because it only grabs the surface of the MDF, and you can delaminate the material in that situation. If you want some pics of the construction of the box, let me know, and I'll e-mail them to you.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Definately go with 1" mdf!!! I used 3/4" mdf with my alpine type r's, baceing and all. Fed each one 500wrms, ( 3 of em) and the top of my box cracked open during break in period, not even close to half volume.

Its best to over do it the first time around.

Hey is like the more "generic" sound dampening applications such as "fatmat" worth buying? I dont expect it to be top quality dynamat.. but i dont want to spend $150 on 36sq ft when i can get 100sq of fatmat for $100...

Look for WEBTROI on e-bay and he can give you a smokin deal on Dynamat X-Treme. I used seven 36sq' boxes to do my 300E top to bottom and front to back with multi layers in trunk and rear deck. It sounds AWESOME! No rattles anywhere and it is the quietest driving vehicle that I have ever been in with the D-Xtreme. I will have it SPL'd someday when I find someone with a good meter.

If you buy from him, tell him the folks with the EXTREMELY LOUD, HARD POUNDIN' gold 300E Mercedes sent you. You will definitely get hooked up. He cannot believe how hard my car pounds and how clear the sound is. We really pissed off some of his shop complex neighbors when letting him hear how it sounds. I thought you were allowed to be LOUD in an industrial shop complex!? something louder? - Page 2 - Last Post -- posted image.
