i have heard from a lot of people say that they had so much air pressure (from their audio system) in their car that they cracked or shattered their windows.
Is this possible?
Just how much pressure will you need to shattered a car window?

 

as far as i know its impossible, at most i think they can spider web (which isnt very believable either)

 

Yea but it takes a serious system.. like burps 160+

 

the car isnt sealed tight enough to build much pressure so its impossible in a normal vechile.

Now a van with a wall and doors that are sealed up maybe crack one.

 

Oh, its definately doable. Seen it done quite a few times.

Tommy McKinney did it at World Finals... Ill post it if I find it.

 

Pipo did it as well, that video is easy to find.

See my story just posted the other day about a client of mine at the link above. Yes, it is very possible. But, usually on small cab vehicles like pickup trucks (his is a 2005 Sierra Crew Cab) or small SUV's. Never seen it on a car where the subs are in the trunk. Although, like with this last client, I have seen the rearview mirror rattle so bad that it breaks the button off of the glass and takes a chunk with it in cars and trucks alike (causes the windshield to spider crack after it falls off also sometimes).

In the case above, that is two 15" MMats in a sealed box pushed by two seperate JL Audio 1000/1 amps (2000 watts), and two gel cell batteries.
