I would be careful with the RM Italy amps. I have not been able to get mine to operate properly with the KX3 in my mobile. Lots of spurious RF issues and we are super well grounded with ferrites/torroids everywhere.

For now I am putting in an older Icom mobile until the 100W amp from elecraft comes out. It is a bummer but mega mobile is a little challenged at the moment. I may end up using the KX3 on 6m with the mirage amp so two rigs in the truck. Not optimal but I cannot let my KX3 hang on the shelf.
