I have an Audiobank F45, 4 channel amplifier (75w/4 ohm, 120w/2 ohm) that I want to connect to a Herz HX250D subwoofer (450W max) which has two voice coils of 4 ohms each.
I had thought of two options:
1) in using all 4 channels, with two bridged outputs for each 4 ohm coil.
2) use only 2 channels of the amplifier in bridged mode to feed the two Hertz coils in parallel (2 ohms) I don't know if this amplifier is stable in brigde at 2 ohms
What do you think is the most convenient option?

Or should I choose another amp?

Thanks in advance
