I wanted to know that, for example you have a sound system and it can go faster than sound. If it goes twice the speed of sound(343m/s) would you be able to hear the stereo?

The answer it yes, but with a twist. First of all, I presume that the speed that that you are referencing the the relative speed from the listener. If they are travelling together, then there is no change at all.
The twist is that it depends on whether it is coming at you or if it is moving away from you. If it is coming at you, it will be travelling faster than its sound, so in effect you will hear the closer sounds before the sounds from a distance reach you. It would likely sound like it is playing backwards up to that point! Travelling away will simply extend the time frame for the sound.
What will be happening will be shifts in the sound waves. As it is approaching, the sounds will be compressed, so it will sound higher in its pitch. Travelling away from the listener, it will be stretched, yielding a lower pitch. These are known as blue shift and red shift respectively, a reference to how light waves are affected in the same set-up.

The speed of a wave depends only on the medium, so the speed of sound doesn't change. The apparent frequency can change, but that is due to a moving source or a moving observer which gives rise to the well known Doppler Effect. For a moving sound system moving faster than the speed of sound, you get a Mach Cone of sound that follows behind the source but it still reaches an observer. The only way you would hear nothing is if the air was moving also faster than the speed of sound

The sound of the wind at 1540 mph would make hearing difficult. Just kidding.
People on the Concord were able to hear the sound system.
Well, heard they could. Wait, maybe that is why stopped flying? Just fooling around again. Sorry.
A jet passing overhead faster than the speed of sound, is audible after the shock wave passes.
Hope this helps.

Think lightning. You see the flash, but it takes a while to hear the thunder.
So if your sound system was coming at you faster than the speed of sound, you would see it, but not hear it.
But the sound IS coming. After the system whipped by you (& presuming you weren't deafend by the sonic boom), you would eventually hear the music it was making on the way.

Eventually it would slow down enough to become a sound wave again but I don't know how distorted it would be.
Sound can travel about 1500m/s in water and still be a sound wave so if you took it underwater and it still functioned it should work.

the fee of sounds is approx. 3 hundred m/s (1000 ft/s), on an identical time as the fee of sunshine is 3 hundred,000 km/s (approx.a hundred ninety,000 miles/s). as a result, the sound arrives some million/3 of a 2nd after the corresponding circulate, i.e. starts off to be recognizable.

The sound waves would increase in energy and be heard as sonic booms.
