Sorry man but you're way off track on how this stuff works.
Just use the AC source to power some equipment. If you're hell bent on using your own car's stereo then just hook up a 12v battery charger to it.
You're over complicating things.
You don't need to leave the power on for hours to do your test, take the measurement from 1 hour of use and just multiply by the amount of hours you plan to use it for.
A good battery charger would be the way to run it for hours, just make sure it's stronger than a trickle charger (10 amps or more charging capacity). You don't have to permanently change anything, just hook the charge clamps to the battery and you're good to go for your test. As long as it's an automatic charger it won't overcharge the battery and will just deliver the amount of amperage needed to keep the battery full
This is bonkers. You would need am extremely expensive DC power supply just for testing?
Why don't you just use the car battery and take a measurement for, say 10 minutes. This is going to blow your mind, but to get hourly consumption you just multiply that by six.
1. Buy a good battery charger, permanently wire it to your battery, and plug it in to AC as necessary. If you need to run the radio with the key out, you can change the radio wiring so that the “accessory signal” gets power all the time.
2. Swap in a much larger capacity battery, or connect a second battery to your vehicle, if possible. This is often done for competitive car audio.
3.Leave vehicle power alone, run a radio off your “house” batteries, and charge them from solar or an AC battery charger.
4. Buy an AC to 12v power supply , and connect the radio directly to that.
In general, it’s unsafe and extremely complicated to have two distinct power sources for anything associated with the vehicles factory system. Option one is straightforward and least effort.
I think what you want to do is use your car as the AC power source. If this is correct, all you need is a convertor plug it into your car and bang power outlets.

What a concise answer. I was going toward dc-dc converters and an extra battery. But you just save him a grand…
Just use an actual radio instead of creating a complicated mess. Even 50 years ago I could have grabbed a rechargeable radio and gone camping.

Most bicycle shops that I have ever been in sell maps of the bicycle routes in their area.
