Ok, in this thread I'm going to post my progress repurposing an old ATX power supply to run a (way too powerful) car amp off wall power. At this point I don't even know whether the amp works, but hopefully I'm gonna find out!
You could say this is my first real electronics project.

First off, thank you to @virbonus@sueden.social for providing me with the PSU! The idea is pretty simple: combine the different 12V rails from the power supply into a single connection for high(er) current. This power supply has 4 12V rails spread across multiple pins that (according to an online source I found) provide 6A of current each. Soldering 3 of those rails with 4 pins each together should be enough to distribute the current and get the maximum possible power out of the PSU by my calculations. 2/?
