Speaker crackle noise

I'v got a problem where when I turn the volume past 19 or so (not very loud) the speaker's crackle as if the bass is at max. Iv tried two diffrent head units and two sets of speakers. Mucked around with the head unit setting's with no success. Im not running any amps or sub's just two front speakers. Tried re wiring the speaks with new wire, cleaned up the grounds and also tried grounding each speaker. any ideas on whats wrong!
