Yes I have and they are a top tier company IMO. I helped my brother a little with his install on his 2017 CVO SG. He purchased two Diamond Audio 10" subs and amps. I wish he would do a write up on it and post it here. He's running a total of five amps (three Boom Audio II amps and the two Diamond amps = 1900 watts) and six Boom Audio II speakers on his scoot.
