Play with RCA cables, L/R on amp.

Look at crossover. One badly burnt resister, one mildly burnt.

Order 2 new crossovers. Take speakers apart. Replace crossovers.

    Bad internal wire or connection.

    Why order new crossovers when you could have simply replaced the resistors for considerably less money!!!

    Because one was burnt so bad the board was literally fried and delaminated.

    Note on these speakers the wires are soldered onto the crossovers so changing the crossover also replaced every wire in the speaker.

    Ha, good reason.

    Are the jumpers in place and are they screwed down tight?

    Problem has to be with a faulty crossover. I know it's a pain, but swap crossovers, only way to know for sure.
