This sub was connected during a close lightning strike. A voltage spike went through audio lines and damaged a number of amplifiers.

Most of them had their input section blown out.

This one probably has a damaged input section, but it could be worse than that.

The actual damage is unknown.

The unit powers up, but there is no sound.

Internal fuses appear to be OK.
