Not to derail from the OP but I took a look at the MB Quart na2-500.5 since I am shopping 5 channel amps now. It seemed a bit weak on the 4 channels - at 4 ohms (which is what my replacement speakers are) it is only 40w/channel. That’s the same as the OEM (Nokia?) amp rating. If anyone has a 5 channel amp they like that puts out 80+ watts per channel at 4 ohms I’d love to hear about it.
