So if you don't make sure all the components are in the on position the system won't work, if you don't have the volume control adjusted you won't get any sound. So you get all this calibrated before you put it the bucket cause it's so much easier that way. Once you install everything inside the lid, and all the components are on, flip on the master power switch and adjust the master volume control and the helmet comes to life!!! You can hear fingers lightly rubbed together from across the room very clearly its amazing!!! be careful at first cause you'll think you want that sound up but the first time someone makes a load noise, WOW you'll turn it down lol.
