Nolyn Acoustics review: Don't buy systems from this company – awful quality

I went along, when the truck of Nolyn Acoustics stopped near me. The driver said that he was selling the acoustic systems and wanted to offer it to me. The prices weren’t high and the seller provided the discounts for everything. I decided to buy and it was mistake. The system was so bad that after I switched it on, it uttered strange sound. It didn’t switch on after that. I couldn’t find this man and didn’t get refund.
