Stock Radio Voltage out to power amp December 03, 2018, 04:33:41 AM I know with the stock premium sound in our cars the amp takes 12 volts from the head unit. I know on the later style head units there was a switch at some point in the mid 90s to where the power output to an amp was 5 volts.....Anyone know when that exact switch was made and if any of the mid 90s JBL amps are 12v or 5v?
