    For those that are not familiar with or have not looked at a typical head-unit wiring diagram, the dash "stereo" switch is not "powering" the radio. There is a bit of misleading info in a couple of the recent posts here.

    A typical head-unit has a yellow wire that is a constant battery positive. This is the wire that the head-unit draws its operating current through, or in other words, "powers" the head-unit. The dash "stereo" switch simply applies a 12 volt turn-on signal, same as the head-unit does doe the amp, to the head-unit to tell it to wake up. This is a red wired at the head-unit and doesnt matter which battery it comes from. As mentioned earlier, its the Yellow B+ that matters. If the amps and that yellow wire, and any peripherals like an EQ, are drawing from different batteries, you are almost certainly going to get noise.

    I hope this clears it up for those installing your 2nd battery bank or those dealing with noise.

    Thats the thing, unless that B+ wire is hooked in through the huge positive cable from the starter, they're on the same power source. I gotta crawl in there tomorrow and unhook it and run it over hard to the house batt to check.
