I think I might have missed something when I added the new amp, speakers and battery. What is the preferred method for moving the wiring on the head unit to the new battery? I'm assuming you do so that all the audio is on the same battery, separate from the engine and other accessories. I haven't looked at it recently, but is there a power and ground that needs to be moved? I've also got a remote switch for the HU by the throttle. How is the wiring handled for that?

Thanks. Just need some help thinking this through.
