I just upgraded last week to the KMC5 from my 3 year old KMC 10. I wanted the Sirius XM capability since service for streaming off my phone can be sketchy where I boat and I already had the Kicker remotes installed so I didn't look at any other brand. They seem to be sold out out currently at most places, so they must be popular at the moment?
I have been extremely been pleased so far and the different zone capabilty and other functions are nice.
