I have seen to many B2 amps blown up. I have 5 in my garage that I can not get repaired. I have a teammate that blew up both of his M16 Great white amps. He has been waiting 6+ months for them to be fixed under warranty. I would stay away until they get their shit together.
6+ months is way to long to go without your system. My teammate can not even get an answer on when he will get them back. he payed big money for those amps.
Maybe somebody from Skyhigh and B2 will read this and help get things moving.
