Interior speakers went out on 2012 RZ4

[CountryDMan]

Hey all,

Today all my interior speakers went out on my 2012 RZ4 (tower and sub still work). I checked all the fuses on the amps, but none were blown. Any ideas what could have caused this?

Thanks

Hope u have better luck than me but mine was the amp itself. If your tower or sub are on the same amp would be good news that it isnt the amp. Maybe fuse from battery to amp?

On the factory system, in-boats and sub are on the same amp, but receive a different source input. I would start by checking the RCA cable connections.
