Car audio. can jbl amplifier power my front and rear speakers correctly?

Question

I have front components(tweeter and woofer) and cross over, the rms is 70 watts, and the max is 210, the impedence is 4 ohms, and my rear speakers are 2 ohms, how can the amplifer(4 channell) power two sets that have different impedence, 2 v. 4 ohms?

Answer 1

it will power them the same but the 4ohm speakers will be getting half the wattage of the 2ohm speakers
