[Joseph M 10+ year member]

thats the set up, the box is lil under 7 cu ft, tuned to about 35. and i am rumbling stuff, like knocking stuff off walls, but i probably couldnt do a hair trick? is this normal? or is the box to close to the hatch and not breathing?

u only have 1 sub, youre not moving a crazy ammount of air

well...my brother has a 9515g in a trunk of a neon and when we took his speaker/box and put it in my car, it was moving air. so my question is. is it normal to rumble stuff but not move any air with a 18

even in his car he is moving more air than me in a trunk.

anybody with a 18/ or had a 18, maybe want to post a video?

Build another box - tune it lower. See if that gives you any more flex/air movement. It might just be the tuning? I'm probably wrong though

As for the guy saying that one 18 cant do a hairtrick - you are mistaken - there are a few people who can do hair tricks with one 18 when done correctly.

And I would assume you're in some type of SUV? Try a lower tuning.

how much lower? 32?

28 hx for hairtricks.BTW single sub set up **** *** ,get the second then its worth the hair trick.

not really worth buying a 2nd one. i've seen impressive things done with single set ups so i dont see why it would "**** ***"

Try something stupid

Try 25, or 28. Then modify until its where you like it from there. That's what I'd do - that's the reason Aeros are so much easier than traditional ports, easy to change the tuning
