if all your speakers come back on and sound normal I would suspect the amp 1st and maybe the headunit 2nd. you can replace with aftermarket speakers. the hk amp more then likely won't notice the diiference "load" wise.

sometimes a bad, shorted out or grounded speaker or speaker wire can cause this issue. you can try shutting the radio off or disconnecting the battery and reconnecting it or turning the radio back on and listening for a pop or click or some weird sound to come from one of the speakers. if this is the case I would disconnect the speaker and turn the radio back on and see if all the other speakers work. the radio could be shutting down the audio output to protect itself from damage. if you have the factory amplifier a fuse could be blown for it or it could be doing the same thing or be bad.
