IF you are going to install amps and a subwoofer, then I recommend going with a large gauge wire (with a heavy duty fuse inline before the entry point on the firewall) from the battery to the inside of the cab and then use a fuse block to seperate the wiring out for the amplifiers. That way you are running a full 12 volts to the amps and not off of your factory fuse block in the cab. The radio can be powered from the fuse block but the power needs to be "Clean" for the amps. The blue or blue and white striped wire will be the "Trigger" wire for the amps to turn on. It will be marked on the radio schematics. If they are of a good quaity the amps will have a connection for the trigger, power and ground wires. The yellow wire on the radio will need to go to a constant 12 volt source (Not switched on and off) to control the memory in the radio.
