Not a green light comes on like normally... a yellow one comes oh

could be the wires is bad or someplace the power wire is grounding out or the fuse or fuses is blown. or could be not enough voltage but highly doubt it.

Amp burned out

yes you shorted the output transistors and replacing them will fix your issue. inside the amp you will find three legged transistors that mount to the amps body/heat sink. replace all of them.

good luck man.
