Isolator Questions

With that one, the issue is that once the car is started, your Redtop is still going to see the load of the audio. I think that is what you wanted to avoid. Basically the solenoid style like the one you linked only separates the batteries when the car is off. The diode/FET type keeps them separate all the time. The difference between the diode and FET style is that the FET style has less voltage drop.

I don't think I want to go with an isolator just looking at it. Losing power and whatnot. And I can use the upfront battery as a caraudio battery. That's good because I don't have too much space.
