A 220 820 02 02

Hello, I have a woofer from the S Class exactly A 220 820 02 02
Does someone know what is the speaker power? Because I want to make a box for that woofer to install it in a non mercedes car.
So I need to know what is the right amplifer power for it.
Thanks in advance

You can measure the resistance of the woofer and calculate the power of you want to be sure

Hmm, calculating the power isn't as straight forward as I thought it'd be.
I'm not sure.

You could try and search for the wiring diagram of the entertainment system in EPC/WIS

The woofer has 4 Ω (see pic below).
Battery is 12.4V.

Power = V² ÷ R = (12.4)² ÷ 4 = 38.4 W.
