Replace with one that meets your needs.
My Stereo is he iRV brand and the only reason I haven't junked it yet is that I haven't found one that meets all my requirements
12 volt operation
HDMI Arc input
Three speaker zones
Built in DVD/CD/MP3 player
And a reasonable cost.
I'm with you on the speakers. I've had clock radios that produced better sound. Right now I'm using a small sound bar so when I play a movie audio doesn't sound like it's coming from a pre-schooler's toy.
