Standard audio system OEM radio poor quality music problem

I know that there could be something wrong with my radio because it was flooded before by a mold remover :lol: but everything dried out and radio works, but the quality of sound is very poor, basically, my tweeters works the way they should but main door speakers play in the same quality as tweeters
now is my question, is there some type of mini amplifier in my radio that died? or some fuse died? i just dont know what to think about it
