Question about Sony XM-2252HX Car Audio Amplifier
The idle current (bias current) of the output section is set at the lowest point that will prevent notch distortion. Setting it higher will only make the amp run hotter. It has nothing to do with the protection circuit.
You should check the woofer's DC resistance with an ohm meter to confirm that it's close to the rated impedance. You should also check the wiring to make sure it's not shorting to ground (which could cause the amp to go into protection).
