You def don’t need a high powered alt unless you running 1000’s of watts...
first check if your alt is working correctly..
car switched off should be 12.4v , car switched on should be 14.4v
Next get a bigger battery and do a big 3. Search google for ‘big 3’ if you not fimiliar with this term.
If still you having electrical issues, then check your relay, that might be damaged and draining current
