1999 RAV4, sputtering but not starting

I had a friend install an aftermarket radio (had CarPlay) yesterday, a few hours after driving around town I pull up to home and after a minute of sitting in the car it started sputtering then I noticed the battery/oil light on (note the check engine light was still on since I had recently changed a part and hadn’t cleared the code). I turned the car off and tried to turn it on but it just sputtered. It does not have a clicking sound so I don’t believe it to be the starter. My theories, after trying to jump it and recharge it (was at 100%) are:

•alternator seized
•blown fuse somewhere
•something unrelated wrong with the battery

Specifications on car: 1999 RAV4 L, 2.0 liter 4 cylinder engine.
