box for 4 - 18s bouncing

[BeachJoshua]

i swear,,,,it does jump up and down on really low stuff,,,i will try to vid it,,,,but it does ,and it shakes itself foward and backwards

Less talking more uploading, start using periods not commas.

here is a few vids showing the box jumping.. at least an inch and a half in the trunk.

a woofer cycling 1 to two inches 20 or more times a second has ALOT of force

jesus,,,i thought this was a damn car audio forum,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,not a fucking grammer class. if your more intrested in trying to prove me wrong by crying vid vid vid vid..or if im using commas or fucking periods..why dont you guys let someone who can answer the questions do it if you cant, or dont want to help.. i think meade himself would be more helpful to someone about the audio question,than so concerned about if im using a comma or period.....

chillax bro we just want to see videos because not a lot of people have their sub boxes jumping half an inch to an inch

and as for the guy who just posted the video.. its a little different when you have a smaller box with less woofers, not much weighing it down so IMO you have a higher likelihood that the box will jump on lows

I believe it.. I just want to see it

Wow, baffle wobble much? I would add another baffle and some vertical bracing. Also bolt it down to the floor with L brackets as suggested above.

EDIT: Sorry thought that video was of his. NVM. Same could still possibly apply.

ok,,,but i only wrote ABOUT A HALF INCH,,,,about.. im trying to say that i dont have a camera with that good of frame rate to capture that,,,,about half an inch also means,,,3/8,,1/4...7/16,,,get the picture....i just want the question somewhat answered,,,,will it take away db by bouncing

[chewie]

actually that baffle is supported vertically and the video makes it look like its wobbling but its actually just jumping..

those are two 15s in a 6.8 cube box after displacement

my box is double baffled all the way across...and internal bracing

and to awnser your question i assume it would eat something up not that you would really notice it by ear.. if you can put bolts through the box into the floor than go for it.. it will also deter theft..

i have a box for 4- 18s in a 01 yukon,,,and when it starts hammering the lows,the box actually jumps up and down about half an inch...is this causing a loss of spl,,,and will bolting it to the floor gain me any spl

mine kinda tryes really hard to jump alittle too lol
