Question about American Pro VS-2043 Car Audio Amplifier
This is a Sony XM-ZR1852, 1000w amplifier with two Sony 1300w subs plugged into it. All other speakers work fine and the deck is working fine also. I checked all connections to and from the amp, and there were no signs of a loose connection anywhere. The amp turns and lights normally, and I hooked my subs into the home stereo and they work fine also. If there were a blown fuse, the power protector light would turn red but it remains green like when it did work. I'm stumped.
You might have blown your amps channels. try a new set of rca cables - I used to go through them like candy.

Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier.
As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.
