I bought a 410 b series ampeg cab along with a ampeg svt3, both brand new, and 4 days later the cab blew. So i took it back, they fixed it, and when i got it back(4 weeks later) that night i was playing it and it was still broken or it broke again. So i took it back and they gave me a whole new cab(the 410 classic series), and i left feeling happy. A week later the cab is blown. Im thinking theres something wrong with the amp because im not blasting the cabs at loud volumes and im not clipping it like crazy, i hardly was clipping at all if any. Any advice anyone?
