Denver area '87-'88 5000CS parts car?

[DeWitt Harrison]

Please don't ask why but I'm restoring the original "10-Speaker" audio
system in my '88. I have two bad OEM speakers: front dash and front door
(low frequency unit with integral speaker grill - grill color is black).
Would not mind acquiring more of each, tweeters also. Any leads would be
greatly appreciated.

As a side question, how can audio speakers go open circuit just sitting on
the shelf? Gradual corrosion at the internal wire connections?

I'll bug Chris at Force5 if nothing local turns up.

Thanks much,
