Help with Speaker Amps!!
I have an 89 coupe with original Bose Speakers. Three of the four are working and I believe that the capacitors are bad? I removed the two rear speakers and opened the amps. Now the questions -
There appears to be a glue on the capacitors and surrounding area (orange in color). What is the best way to remove enough of it to get the capacitors out?
I am following an old post that says 90% of the time it is the larger capacitors that go bad, and just have to be replaced. They also said that you can use 1000uf 16v as a replacement. I have them, but they are taller that the original ones' and therfore the metal cover will not be able to fit back on. Do you really need that cover?
One of the speaker wires is broke at the connection (the wire comes from the center of the speaker to the outer part and is connected to the metal clip). It appears too short to soldier back on. Any suggestions on extending the wire, etc.? The area that you would have to work with is very tight.
Any other suggestions-recommendations on the above issues would be greatly appreciated. I would like to have the speakers done before Carlisle this weekend>

an easy way to see which capicitor is bad is by looking at the tops of them. The bad ones almost always are bubbled at the top and sometimes even start to split on the top.
On the wire, try to solder on a new wire if there is enough room.
Ive heard of people using a knife/razor to just cut away at most of the glue. But i haven't tried this, so im not 100% sure. My gess would be that once you got enough glue removed, you can melt the rest away with a solder iron.

Thanks. The capacitors appear to be in good condition, with no signs of what you described.
The wire is tough to ge to. the speaker is on top, the magnet is on the bottom, and the speaker casing (with small holes) is on the side.
Any more help out there?
