The other day my tweeter in the o/s rear door gave up and made the lower speaker (same door) make a horrible 'droning' type noise! I disconnected both speakers, this however made all the other speakers emit a low 'buzzing noise'. Not being able to take it anymore I went to the scrappers and got another tweeter, plugged it in and hey presto. no more buzzing! - Thing is, now there is very little sound from either speaker from the rear o/s door! If i turn it up super loud, all the others speakers are blasting and the rear o/s is very faint, my god, what is the problem here!!!???
