Stereo System Correct Wiring?

Of course most batteries are closer to 70AHrs and the draw will be closer to 100mA which would be 30 days.

No way 100 mA. Even cars do not exceed 50 mA with all of the electronics they have. Modern 2010+ model cars I usually see about 20 mA. That being said, it's still possible to see a car go dead 30 days of sitting, but it all depends on how clean and age of the battery.

No...you need the red hooked up to a switch. You do want to run your radio with the engine
stopped right?

Do you have a main battery switch to disconnect your battery?

Okay.. So if theres a switch involved whats gonna be the order of the wiring

Not sure what you mean by that.

Input of the switch goes to constant 12V through a fuse and output goes to your stereo. Is that what you want to know? And the only reason I say input is because some switches are lit switches.
