This is my first real post on this forum, so hopefully I'm following protocol and etiquite.
I few years ago I bought a Sumiko S.10 subwoofer. I really enjoyed it, but eventually it just stopped working. I'm far from a DIY audio guy, but was brave enough to remove the board from the back of the sub and look it over. I don't know anything about electronics, but found something that didn't look right. There is a burn mark on the board. Check it out on the bottom right of the image:
Here's a closeup of it:
I spoke with the US distributor of Sumiko. They told me they could sell me a new board, but it came with no warranty whatsoever. Given the reputation of these boards failing, that didn't sound appealing to me. I'm told I can salvage the sub just buy installing a different plate amp from Dayton or Parts Express. I don't really know what to buy, though. Also, I was under the impression there should be just a couple wires to hook up, but it appears the Sumiko has more than that. I think if I can figure out how to wire the correct aftermarket amplifier to this thing I can get it working again. A friend of mine has offered to mount it properly to the back of the sub. He works in a fabrication shop and has some experience with that sort of thing.
So here are my questions:
1. Should I buy an aftermarket amp for it?
2. If so, which one?
3. What do I need to do to wire it up properly?
I'm not afraid to spend a few extra bucks to make the amp sound at least as good as it did originally, if not even better.
Here are more pictures of the subwoofer internals that will hopefully help:
If anyone has guidance for me I would really appreciate it.

Looks like someone's been in there before you. What's on the other side of those rather messy looking soldered connections?

Thanks for the quick response, Jeff. Why do you say it looks like someone has already been in there? I bought the sub new in a sealed box and have never taken it apart before this.
This is what it looks like on the other side of the burned(?) connections:
The burn marks are where the orange/brown donut thing attaches.
