Check the DCV between 'A', 'B', 'C', 'D', 'E', 'F', and 'G' against 'GND'.

The woofer amplifier has DC offset of 7.3VDC on test point 'C' so the speaker relay is not allowed to come on.
The Tweeter amplifier has 0VDC offset on test point D so that is good..

You will damage the speaker due to 7VDC offset.

The problem is in the woofer amplifier, the output should be 0V not 7V, that is where the problem is.
