Hello, best regards, friend Gusty, if there is audio in the tweeters, it means that the outputs may be ok and the problem may be either in the big horn that is burned or in the defect in the crossover card that is usually internal next to the horns these resistors or coils of the crossover are usually damaged that by the vibration the welds are broken or come off and stop sounding, you must check if you have the means to do so the horn or big speaker to rule out that it will not be burned , then check the crossover which is where all the connections for tweeter, media and speakers come from, so you can find where the fault is. regards
