I jump started my 01 x5 4.4i and all of a sudden my speakers have a loud noise like if it was on an unknown radio channel, I have a Lear amp hifi dsp! Did I blow the amp? Or speakers? Only the front tweeters work. There is no water damage in trunk at all, and there is no other problem with the vehicle the jump start ONLY affected the speakers so I'm not sure if it's the amp or the speakers.
