I can show you four speaker database wiring. Two radio fuses, One is battery power, hot all the time, for memory and clock, whatever. The other fuse goes hot with the key on. I believe ignition voltage is what operates the radio. Use a voltage tester at fuse circuits, check for voltage. Also check the grond, black wire. I'm not a stereo person, I'm more of a wire chaser.
