Is it possible to add a LINE OUT to this ZKHT21 2.1 amplifier?

Is it possible to add a LINE OUT to this ZKHT21 2.1 amplifier to connect another independent amplifier and headphones?

I have this ZKHT21 board, powered by a 36 V / 10 A power supply (2 × 160 W stereo + 220 W mono subwoofer).

  • Is there a safe way to do this?
  • Where exactly should I connect L / R / GND?
  • Are any additional components required?

I have basic electronics and soldering skills. I have attached a picture of the board.

Thanks for your patience!

📌 Edit 1: WHY? Because I want the option, now or in the future, to connect another independent device and/or amplifier.

📌 Edit 2: I have already considered possible high-to-low converters, but I don't really trust them, since practically all of them are rated for NO MORE than 40–50 W per channel. (My amplifier is powered by 36 V / 10 A.)
