Angry shorted out my car??

Goddamnit guys i think my car has a major electrical short. I was changing out the fuel filter so i asked my younger brother to unplug my battery.. he unplugged the positive cable and left the negative on... I realized this afterwards and out of instinct i plug it back in not even thinking.. when i turned my car on, and drove around.. my subwoofer was going off randomly and loudly.. my radio was off ... Volume at Zero.. now my fuel pump isnt going off... Wtf ... How can i fix this

take the negative termnal off... wait 15 min start over,

make sure your possitve termnal is nice and clean and tight and seated correctly... Then do the same after the 15 min for the negative side,

Sorry I haven't followed up..
okay so I did that.. and after an hour nothings changed.. but I unpl;ugged it (-) over night and came back to it in the morning .. plugged it in and my car started flawlessly (ive been having bad cranks that sound like a shtty starter) for the first 5 cranks (driving around, turn off to go in store, come out, turn on drive elsewhere etc), they were smooth, perfect start ups .. after that.. it went back to its usual shtty crank state and its been like that since.. I haven't tried unplugging both (+) and (-) at the same time yet.. should I try that?
