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.
Im not using one wire.......and there is only 4 12v wires coming out of the power supply.....all others are 5v and 3.3v

the two wires i had there were not hot after a couple of hours of use....you have to keep in mind its only 6" long.

i did put all 4 wires together now but it probrably wont make a difference.....

your looking too far into this...

its almost like your mad that it works for me....
