I bought this ghetto-ass car amplifier for like 5$ that was broken because one of the resistors was jammed so tight between the speaker terminals that it cracked and shorted out. it has a ton of op amps on it (TL084CN) and a TL494.
Im pretty new at EE, for reference i just figured out the difference between a bipolar and unipolar power supply. What can i build to get the most xp?

Build a little inverting amplifier from op-amps. It's fairly easy once you get over the learning curve of looking up the datasheet to get pinouts, knowing what to connect where, making the connections *to match your design* (protip: you'll fuck this part up more than once).
Once you have it built then try rewiring it to make it non-inverting, then differential. They're easy modifications.
Once you have a basic grounding (pun intended) from doing this then try building a power supply - this is a rite of passage for most electronics hobbyists and there are loads of guides online for different kinds depending on what bells and whistles you want. It's a bit of a catch 22 in that you'll probably need to buy a power supply first to be able to build and test one...
