Finished my helmet, was not as bad as I had thought it would be. I put the fans and flat lenses in. The AMP that I had ordered will not work. When pluging the mic in,there is nothing but a faint white noise that is uneffected by the volume control, but if you listen close you can here radio signal of some kind. Anyway I emailed the seller . So I am just alittle ,Ok majorly dissapointed about this. (One of several set backs so far)
