How to tell if box is leaking air?

[Big Green]

How can I tell if my box is leaking air. What does it sound like, and if it is how do I tell where it's coming from?

With your subs playing loudly, run your hands all over the box, and feel for air coming out. You should be able to feel it if it is leaking. Take extra care around where the sub seals with the box, that spot can leak easily. Also if you are using cup terminals, those leak sometimes too...

Another way to tell, is to gently push down on the Sub (with stereo off) and let it go. It should take 5 seconds or more to rise back up. If it returns back to normal position any less than that, could have a leak.

I don't know about pushing on the sub, but you can get a piece of TP and hold one end and then run it over all of the seams to see if it flaps then you've got a leak.

Also you could just reseal the whole thing, but wait there's more, you could then rewire and recarpet then get new subs, wait what the hell am I saying just go to Walmart and buy one of those kicker boxes with the neons, now seriously folks, I'm just kidding, those boxes are trash.

Hmmm... I just tested that out on mine (not that I thought it was leaking - but I thought this would be interesting to see) and I could not even push my subs in more than like a tenth of an inch, and they have an xmax of .55" either way. What's the deal with that? I guess if it was sealed really well then you would not be able to compress the air inside without pressing really hard, which I did not want to do (Don't want to dent any aluminum cones! ). Getting my subs moving back and forth when I have the volume cranked must take some serious electrical power!
