    I’m swapping the radio system in my 2005 prius, and after taking out the stock radio the wires are only transmitting about .5 volts instead of 12. All fuses have been checked and the new radio works. Any tips?

    There's only one or two power wires right The rest are speaker and what have you so you are measuring the correct wire/s?.. And believe me Mysterio needs the 12 volts that it gets from the necessary wires.

    Double-check the diagrams and what's being measured?

    Nope you're going to need four stiffening caps four gauge power wire throughout and 10 gauge speaker wire I need to change that immediately not.
