00:23 How much power adapter is required to have good audio output from a Fosi Audio system - 32 volt x 5 amp = 160 watt or 32 volt x 20 amp = 640 watt or a 36 volt x 20 amp = 720 watt. How much audio difference can a powerful adapter produce when fitted into a Fosi Audio system.
02:16 How to use the pre out in Fosi Audio to get the best audio clarity with room shaking sound. The pre out in Fosi Audio require and good amplifier to produce good audio signature.

03:54 My room is 224 square feet in which I cannot play the Fosi Audio in full sound as my computer table and glass use to vibrate and I can feel the vibration in my body also. At 75% volume it is more than enough and the bass vibration even travel to my other room.

So just imagine what type of audio it can produce in your home. Actually it can shake your entire home with good audio.
