So as the title stats when you are using RCA Y Splitters for either front or rear output of the head unit do you connect to the amp using red to red and white to white or is it one red from one splitter and one white from the other splitter? I keep seeing so many different diagrams and second guessing myself. What I am trying to accomplish is two horns and two 6.5 up front and two 8's and two horns in the bag lids. The amps I'm using are SD 800x4 and SD 400.4 all 4ohm amp's and 4ohm speakers. I know it gets asked a million times but due to the horns being in the front and rear I was thinking of splitting front outputs from head unit to Channel 1-2 of 800x4 and Channel 1-2 of 400x4. Then splitting the rear outputs to channel 3-4 on the 800x4 and the 400x4 to kind of keep the F-R fader or am I assuming wrong? Pictures and diagrams are VERY WELCOMED
