stereo problem after blowing main fuse
 

so i blew my main 120A fuse a while ago when i shorted my battery lol. also blew 2 of the fuses above the dead pedal, i believe they were the "door lock" and "room" fuses. i've replaced all the blown fuses.

now everything is working perfect except for low stereo volume..

i crank it all the way up and it is barely audible and crackles/ cuts in and out.

i checked all the fuses located underhood and interior fuse box.. other info that might help.. the car is 94 with stock cd and cassette.

anyone have an idea or was able to fix a similar problem, i searched for an answer but it doesn't seem that many owners have had the same issue, or never reported but regarding a diagnosis of the issue or a fix.

im troubleshooting the front relay box at the moment.. looking at FSM pages J1-29 and J1-30 for short connector testing. vehicle is non-bose. im no good at electrical stuff though, might as well be in french

wiring diagram,

can anyone explain the short connector in non-bose fd (what does it do and what are the symptoms when it has failed)

i tested for continuity between terminal A and E per the service manual and... it had no continuity.. manual says it should.
