List your amp/load and music tune/preferences goals... decaf tune?.. low daily?.. hi-daily?.. Spl?.. and someone will help... music tastes matter so say what your goals are... to slam, sub hard, all around, rock or pure SPL...

The box I have right now is 10cf but subs face up and so does the port and it hits but when I face the post to the back it’s slams but then it’s like having a wall and I’m not liking that

12 tuned to 36 subs up at hte very back of the box, port back along the bottom of the box with atleast 4" from the hatch

From my experience, DDs like big boxes, 10cf seems small for a pair of 18s.

The box was a given to me they had the same subs in it. My old set up 2 re audio sx 18s hit a lot harder and box was bigger I want a box like the one I use to have want to see if I can get some help on some prints to make one

Yea my DD 9518 is in 7 cubes net with 2 flared 6" aero's

need measurements. the box i recommended is the minimum and the configuration will sound loudest. FYI you need a 5kw for those woofers

9518g on a 2010 M2a. Need more power for sure. And a 3rd 6" aero

Either a ts 2.8kw or another m2a strapped at 1 ohm. And a bigger alt and batts... and then... and then... and then lol

Too small for a pair of DD 18s and port firing to the back is optimum in Escalade. I'd get them into 14-16 cube, 225 square inches of port area tuned no lower than 36hz.

Should be high 151's with that amp once you get the box right.

Oh I know lol... that's why I'm stalled where I'm at now. If I'm gonna go through the major hassle of pulling the box to tweak amps, it gonna get a huge upgrade while it's apart. And that's big money I don't feel like spending right now lol
