does anyone have a working woofer/driver? for the door speaker for a 2001 lx 470 w/mark levinson pkg or know a cheap alternative.i went to circuit city and they said it was something they couldn't get and couldn't order anything and they rec i call a dealer? i don't want to spend much as it sounded great before it blew-now it rattles something aweful when there is any bass. i am not interested in upgrading the speakers but i thought if someone had 1 or 2 laying around i might pick one up cheap.i know lots of you do upgrade so please help if you can-thanks-ps-i'm brand new to this site so forgive any irregularities
