this would be my reccomendation to you if you plan on adding. you should run the 4g wire back with a distribution block. from the d block run 8g out to your amp and when you upgrade just run another 8g wire to that one (d block should have 2 8g outputs). also run your 4 channel rcas along with your 2 channel ones at the same time that way it is done. DO NOT run your rcas down the same side as the power because it will cause crosstalk.
