Hello,
I got a Retrosound stereo i'm trying to install and it needs 12V of constant power from the battery along with 12V ignition/ACC. Reference here: https://www.retromanufacturing.com/page ... your-radio
Has anyone installed a new stereo and has guidance here?
Thanks!

Re: Constant 12v for new Radio
12V constant is typically power for the devices memory ( programed presets) and 12V switched is for operational power, on and off with the ignition switch, keyed. If you poke around the fuse box you should find both.

So what's wrong with setting beneath a single pull string incandescent light bulb writing angry letters?

Re: Constant 12v for new Radio
Thanks! I have looked at the fuse diagram (here: download/file.php?id=33268&mode=view) and can't figure out which is which. I'm assuming "Radio 6A" is the switched 12V. Which location has constant 12V?MadMC63 wrote:12V constant is typically power for the devices memory ( programed presets) and 12V switched is for operational power, on and off with the ignition switch, keyed.

Re: Constant 12v for new Radio
I think an industry standard is yellow equals 12V constant (memory) and red equals 12V switched power.

A light tester will determine that. Easy to figure that one out.

Re: Constant 12v for new Radio
The ACC terminal on the ign switch is "switched 12V", the + terminal on the ign switch is hot 12V all the time. Too simple!
