A person will hear a hissing bottle when they open a Coke bottle because the drink is carbonated. This is true of all carbonated beverages and it generally means that they are fresh.
The hissing sound when opening a can of soda is caused by the release of pressurized carbon dioxide gas. The pressure inside the can is higher than the surrounding air, so when you open it, the gas rushes out, creating the hissing noise.

Sound AMP problem or failure in the sub-woofer. Turn your speakers up all the way, do you hear any static or hissing? Could be a number of things, and it's not good.
You are going to have to find the leak yourself. Purchase a can of starter fluid. With the engine idling, spray the starter fluid in the area of the hissing sound. When you hit the leak, the starter fluid will be sucked into the leak and then into the intake. You will hear the engine increase in speed. Once you locate the area of the leak, start looking carefully at the vacuum hoses and their connections.
