The drain on the battery from those other items is relatively small compared to the radio and its amplifier. My audio source is usually my phone so to avoid draining the Jeep's battery, I use a portable bluetooth speaker when the engine is not running.Thanks for the response but that makes dash lights, shifter lighs and some other cabin lights to come on which is additional drain on the battery.
The dimmer switch will turn most, if not all of those lights off.Thanks for the response but that makes dash lights, shifter lighs and some other cabin lights to come on which is additional drain on the battery.
