My trunk was leaking in my 1998 Z3 and the water fried my Harman Kardon power amp. I would like to find a working HK amp, part # 65.12 8 399 683 or 188.8.131.520.292. Perhaps someone upgraded their system and has the original amp they would like to sell. I have a Paypal account and you may contact me by e-mail at Ro_Harrison@hotmail.com
. I have fixed the leak in the trunk.
