Hello,
Personnaly i use a Harley Benton GPA-100 (https://m.thomann.de/fr/harley_benton_gpa_100.htm) with a Kone in a Harley Benton G112 Vintage and it work fine to me.
I don’t have experience with other Class D amplifier but i have no complaint with this one.
Next step: Full integration in the cab with some hole and screw for a Cheap Powered Benton Kabinet
