The NTE is not a good sub in that set.
Follow the service bulletin, required, for the overheating and blowing
HOT problem in that model. Plus there likely will be a bad cap on the
HOT driver circuit.

I no longer have a copy of the service bulletin, but if Daewoo is still
in business they can email it to you.

As I recall, the bulletin made some changes to a couple of parts and
added a 39 ohm resistor across the B-E of the HOT as well.
