So Home Depot, here (hear) I come. Actually, they're still open, so I gotta go, thanks guys.
Greatly appreciated, I mean that.

btw, it was the episode where they were trying to find the brown note (a tone around 8-9hz that makes you lose control of your bowls...myth BUSTED!)

You must look pretty cool driving around with earplugs...
why dont you just turn it down if it starts to bother your ears... ???
You will know its too loud when you ears ring for 3days after a good pounding... I know a few guys who have permanent tinnitus... (mostly drummers)... try sitting on stage next to that and you will know what loud really is... a 12" sub and 1kw is nothing...
sub bass wont kill your hearing that fast anyway... my system can do 150+ db easy from a 0db reference (.02mpa) under 80hz and I usually just get a headach if I listen too long... remember those are unweighted peak levels... that would be alot less in A weight.. more like 120..
On the other hand some users may cross thier sub over higher and/or cause a lot of upper harmonics to be produced because they seem to like distortion... that may damage your hearing a lot faster...
FYI you can cause perminatant damage with deck power and 4x6s... thats what Id worry about..
I saw that mythbusters episode.. it would have worked better if the the test was inside a small room... I bet he would have **** and pissed from that...

1) Hearingloss is a function of:
Frequency - Higher frequencies cause damage sooner
Duration - You can sustain short period of high SPL's without damage
Output - The higher the level of noise your exposed to the greater chance of risk
2) Earprotection can only reduce a maximum (around 35-45dB) due to the fact that we hear with both air and bone conduction. So unless you can encase your entire body in cement there are limits as to the amount of sound you can stop from reaching your cochlea.
3) Everyone's hearing is different. Some people may experience hearing loss before others. Other people are just good at hididng there loss. Damage that occurs today may not be noticable for another 5-10years.
If you are concerned at all about your hearing go have a hearing test doen. This will give you an idea of what your hearing baseline is. Then every 2 years re-test.
The best earplugs to use and listen to music are ones designed for musicians. You can get custom plugs ($150-$250) or off the shell ones ($30-$100) called hifi plugs.

It didn't look like output was an issue in that test.

If it was in an enclosed space Iam sure the SPL would be much more intense..... more likley to make the guy puke, have a heart attack.. ect..
Edit: output was a factor otherwise they would have used a single 6.5" and 10watts of power....
