Adding aftermarket radios
Continuing from another post......See the diagram below for using an Aftermarket Head. Notice that RCA jack or preamp outputs are used.
The audio amp section of a factory radio adds noise and distortion and then driving an external amp just amplifies all of that noise.
Using preamp outputs and and external amps is a superior method.
