repairwire
The wire connecting to my sub has snapped off, and it brought the metal connector piece with it.
I don't want to buy a new sub, but it looks like this is going to be hard to repair. Anyone have advice for me?

The sub wire is broken too:
I disagree with Chris in that you don't just want to shorten the cable. It's not the length of cable I'm worried about, but that tiny connector you don't want to replicate. The connector and the wires immediately coming out of it look to be intact. Replacing that will be a major pain in the butt, so I'd go to reasonable length to preserve that piece.
Since that piece is now short, you'll have to make a splice. Just realize up front you're not going to make a splice in such small cable that is anything like the size of the cable. The splice will be big, fat, and ugly in comparison. It looks like it can be made to serve as the strain relief too, so that helps a little.
To splice such tiny wires, see if you can sortof stick the stranded ends into each other. That may take some persuasion under a magnifying light, and then some weighty objects on your bench to hold them in place while you solder. This won't be easy, but it should be doable. If that just isn't practical, give up and bend each wire into a U and hook the two U ends together, flatten them together with a needlenose, then solder.
Once you have the connections made, wrap each one individually in a small piece of electrical tape, then wrap the whole bundle in electrical tape so that is looks like one fat section of cable. Like I said, big, fat, and ugly, but it should work. All that tape will act like a strain relief, so that section shouldn't break again.
Here is the schematic for that circuit board:
As you can see, there is only one diode in the whole circuit, and it's going to be pretty abused by the EMF collapse of the flyback.
So your replacement diode should replace D1. Kludge it in however possible.

These are Faston connectors, or similar. (Faston is a Brand name of TE Connectivity.)
This one is to be crimped on the speaker's wire.
Although you can fix the wire with a pair of pliers too, I would recommend to use the purpose-made crimp tool for it, as the connection will be a lot more reliable. These tools can be pretty expensive, but maybe you can borrow one. Fix the crimped Faston to the speaker's frame with Tec 7 or something similar.
Note that Faston exists in different tab widths, make sure you buy the right size.
