i was testing some speaker and i accidentally got the positve and negative wire to touch each other, my hu is factory and it started doing a very loud defeaning sound, and i started to smell the amp and the protect light is on so i unplugged it.
I think i might have fried the output of the hu
Question i have is i do not know which one is messed up, if i have another working PBR 300x4 can i swap the possible messed up one with the working one to see if its still working? will my mess up my other system if i did this?
I cannot reach the rca to plug in to the input of the amp.
can i get suggestion on how to check
