this is for a 2000 C5 A6 with BOSE system... and its the front pass door

mine makes a horrible buzzing noise when ever it hit a low tone (bass). its only bass, it sounds perfect with all other tones but if i pull off the door panel to inspect it, i'll just replace it assuming there not obsurdly overpriced... but this is Audi so hit me with the wost.

if anyone has upgraded their stock BOSE system and has a passenger side lower door speaker laying around id be interested as long as it was working when removed. TIA
