hi

I'm asking to the good people in LB who knows many things that I don't, if there is some kind of chip "converter" in a way to re-use an old car radio in my garage.

that is because I got some old radios and many speakers too in cars I had before.

so I thought if there is a chip way to adapt one of these radios and a pair of old speakers in a way to have some music in my workshop.

certainly many of you have made that experience before, or saw something similar to that.

any ideas?

thanks in advance

Just buy a power adaptor ( what the Canadians call a wall wart ) giving 12 V and at least 1 A. Or a CB power unit, say 12V at 5A Make sure you connect positive to radio fused wire and negative to the radio metal case.

I tried that, at low volumes I got huge mains hum, and at high volumes the power demand tripped the wallwart (my new favourite word, thanks Macbeast!). The latter can be solved with a bigger power supply, but I wasn't sure how to sort the former. A car radio would never need to have to suppress 50hz on the supply.

Personally my next approach would be to use a spare car battery, and just charge it back up every so often...

Simple transformer
The sort that is used for scaletrics or model railway
Maplins will do a bench transformer you just need to look at how powerfull your radio is

I've got an old car battery that holds a little charge running a radio on my workbench and a small ebay solar panel on the roof to keep it topped up

Several ways you can do this.

car battery and trickle charger.

PC power supply

transformer from various uses

consumption will be around 140w max I guess or 10A max.

Wow, and I though I was cheap using a donated old stereo I like the waste not want not attitude here but question the sanity.

Ahh
Just thought, options are car battery or car battery charger or trickle charger connected to car battery
Any of these solutions will power a car radio in a gatage

PC power supply, all the black wires are ground, all the yellow wires are 12v, green wire needs an earth to turn it on.

Waste of time and money.

I've used one of these to power a radio and the larger size to power 2 12v driving lamps in our blast cabinet .

UK Stock DC 12/24V Universal Regulated Switching Power Supply for LED Strip/CCTV

It works perfectly. Need I say anymore. Just make sure you have the correct (car) speakers.

As others have said why? You can buy a regular radio for £5 or less.
