Simple. Buy an AC to DC power supply and operate the radio off of that. Radio Shack sells them.
has anybody ever tired to use a car radio inside there house, connected to celine speakers or a like. im think about converting a coach into a cafe and want to be able to use a car radio for the music system on both 240v and 12/24 volt systems.
any help will be usefull
i was think a computer power brick could work not sure what wattage i would need
we have a car radio in our caravan, its currently in storage and i can rember if that loses the settings every time we turn of the power. But i am not to botherd if i lose the radio settings everytime, or though it would be a nice touch. is there not anyway of hooking up a standard 1.5v battery to keep the settings?
Just leave the power supply turned on but turn off the radio manually. Wire the 12 volt line to both the switched and unswitched power line on the radio.
Alternatively, you can use a sealed lead acid battery as a backup although you'll need to put a charger on it.
Old car battery and a charger plugged into the wall will also work as long as the charge r can supply the battery. However, by that time you are already up into the cost of an AC-DC power supply so you might as well go with that.
if i was to connect the 12v power charger and the coachs 12/24 volt wiring with a switch to the unit will that allow me to use the radio on both power circuits, if i swicth of the power and turn on the 12v power at the same time will it lose the settings still.
