Need help with car head unit (internal)

[jongig]

So i have a Kenwood dpx503 head unit and it keeps saying protect. I know it goes into protect mode when theres a short ect.... i unhooked the speaker wires and just powered the unit by its self and it still went into protect mode even after resetting it. Now i was reading that if its not the speakers or anything else then its internal damage in the unit. i saw somewhere that if its internal then its the output transistor/s the only thing is i cant find those D*MN things any where. K A1046 Y107 is what it says on them. part number is A1046 or 2SA1046. I dont know the voltage or anything about these transistors so can some one tell me where i can find them or a replacement for it? Your help is greatly appreciated!
