Piece of hose, while playing the sub put one end into your ear the other around whatever areas you want to check. I will make and audible "whoosh" noise if you have a leak.

This or a stethoscope. Playing sub 20hz test tones while doing this will make things even easier to hear.

If you're a smoker there's another way a friend of mine always uses... Move the cigarette around the box and where the smoke starts blowing away you got your leak.

Hold the sub under water and play test tones. If you don't see bubbles you are fine..

I've used sub 20hz sine waves (15hz is good) and just my ear. works for me.

...Never tried that water trick.
