Not backing anything or anyone. But I read a report that was from the maker of the CT amps and they are Korean built. I've heard the ct1400.1 on an smd aa 15. In a Chevy X cab when I was buying his old aq 2k amp. And we tested the amp in his truck and the 1400 was a lot louder. It's been a bit but the 2k amp wasn't one of the cheap amps like boss or pyle. It was a nice amp.
