I want to convey a strong message to an adolescent boy. I'm unsure how to properly construct the sentence. Are any of these sentence constructions correct for conveying:

Regardless of who's son you are, don't disrespect me./I don't care who's son you are, don't disrespect me.

Sin importar el hijo de quien seas, no me faltes al respeto.

Seas hijo de quien seas, no me faltes al respeto.

No me importa de quien seas el hijo, no me faltes al respeto.

(Thank goodness I'm not actually having to use this sentence in real life!!!)

I'm weak in grammar, so any input and/or grammar explanation is appreciated.
