A:AnswerYes I just unplugged each rca plug one at a time from old receiver to new one not to get mixed up
The wiring harness from old receiver plugged into new one and plugged in antennae.Easy to do when staying with same receiver just newer model.I just made sure before I did it that the wires were all the same color and same amount.
A:AnswerYes, rear, front and sub. I believe it’s 4v. Your RCA’s will plug directly into the unit, it Is Not like the other units that have actual RCA leads coming off of the back, just the terminals you plug your RCA’s into. Hope this helps, the Smart Sync app for your phone is the best thing. You can do the majority of your settings and sound tweaking from the app on your phone.
