If its not then why does it say 15a on the 12v+ right on the power supply??
Its like trying to push a softball through a hole the size of a quarter, There is no way you will get a current of 15 amps at 12 volts DC through a 22 awg wire. The power supply is capable of 15 amps but thats at the circuit board before it splits the power over 5 or so wires going to different pins on the connector. If you run your amp for a long time this way you will eventually over heat the wire and probably melt the coating on it and could cause a fire.
