I have the latest 10.1" unit JY-UZS08N4. Its installed in a Ram Promaster cargo van. The 2 front factory speakers work fine. I want to connect two rear speakers to the head unit using the RCA outputs RR and RL. I can not get any output from the RCA connections on the back of the unit. I have changed the speaker settings to 4CH. I have also looked for any other settings that might be causing the problem but I have not been able to get any output from the RCA connections on the head unit. Any ideas? Thanks.
