Hi all, In my Prius 2011, all my four speakers are not functioning at the same time. When in bluetooth mode (BluLogic) only front two speakers are functioning. In AUX and Radio mode only rear two speakers are functioning. Is that expected or is it any wiring issue?
Thanks, where do I find manual on how the wiring should be done? So when I open the radio cover I can try to find miss wiring.
In Bluetooth hands-free mode, only the front speakers might be used, but for the other modes, have you tried adjusting the front/rear balance control, as described in the Navigation Owner’s Manual (PDF), pages 148–150, or the Owner’s Manual (PDF), pages 330–331? Before assuming it’s a wiring problem, since all the speakers are working, just in different modes, I’d start by checking the balance setting described above. The Electrical Wiring Diagram (more info) shows the factory-installed speaker connections, but if the car has a BLU Logic hands-free system (a Toyota accessory installed after the car was built), those connections wouldn’t be shown in the EWD or considered in the Repair Manual troubleshooting procedures.
