I have a Kenwood KAC-9103D amplifier. The blue power light turns on and the fan turns on. The red triangular protection light keeps pulsating, and my subs don't work. I know this is a problem with the amplifier and not the wiring, because I currently have another KAC-9103D hooked up and it is working with no problems. Ive had this amp for a while sitting around the house and Im trying to figure out how to fix this problem so I can use it or sell it. Can anyone help?

Your amplifier is broken, more than likely shorted output transistor(s). They need to be replaced.
