Help on a 18" MT wall build

[skadude016 5,000+ posts]

OK yall. I'm trying to figure out what would do my MT 18" (that I bought off Tuan for an awesome price) good for daily and also the occasionaly comp. I will have around 1800-2k on tap. It is going in a 96' Jeep Grand Cherokee. I know my car's resonant freq now is 45hz. but I know this will change once the wall is in. I was thinking 8 cubes tuned to 36hz with about 175 sq inches of port and a ton of bracing. Let me know what yall think. thanks //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Is this going to be a true wall or just a huge box?

 

[SHiZNiLTi 10+ year member]

It's built as a huge box to start off, but to make it a wall I plan to create a thick frame that will fill in the gaps between the box and the interior walls of the vehicle which will wall it off from the rear of the vehicle. The wall will then be braced to the box making it one solid piece.

no wall?

 

[jellyfish420 10+ year member]

i have no opinion on wall or no wall. but design wise, i would move the braces that are on top and bottom of the sub to the center, by the other 2 braces.

personally, i would rather have a series 6th order...

 

[btnhfan 5,000+ posts]

What I would do is build it thick and bulletproof and use no braces on the inside.
