Hello everyone! New member here and I'm looking for some advice. It would seem that after less than a year my NXG sub has bit the dust. Long story short, the manufacturer wont help me, and amazon cant help me. I know the problem is with the plate amp that came with it, it was notorious for failure after the 6 month mark (wish i knew then). Anyways, should I try troubleshooting this out and fixing it or just replace it with like a Yung or Dayton plate amp. the problem is the unit takes a while to power on and when it finally does, there is no signal going to the driver. There is also a hissy whining sound coming from the board. I cant tell if it is one of the transformers or the caps but i know it never used to make that sound before. Any help or suggestion will be more than welcomed.
