92 ls400 pioneer 2 ohm sub??
I am looking for a replacement for the rear deck sub. It's an 8" pioneer 2 ohm 40 watt sub. I have the old sub, and I know I can cut the frame off and bolt it to a new sub, but I can't seem to find an adequate replacement, plus I've read nightmare stories of cooking the amp with an improper configuration. Any advice from someone who has dealt with this issue successfully would be greatly appreciated

I re-foamed my 2 ohm Pioneer subwoofer this past summer, as it has a very odd resistance that is hard to match.
I used this tutorial to perform the repair, and it came out like new. It's a little tricky, since you can't get your hands behind the cone to support the foam, while it's adhering, so you have to be very careful. You also want to make sure that the cone remains centered, otherwise you will get distortion in your sound. Take a lot of care when removing the old foam and adhering the new foam, as the paper cone is very brittle after 20+ years. I had to perform paper mache repairs to the cone, to close up cracks I accidentally made and retain its shape.
Although I put a UV cover over the subwoofer when I park outside now, it will probably only last around 10 years, as heat and UV eat away at the foam and the paper cone.
Worse comes to worse, you could just leave it unplugged. Any subwoofer from another LS is probably just as bad because of it's age, and isn't worth the money.
EDIT: I believe I purchased these foam surrounds. It's been a while, so don't take my word for it. Take some measurements and double check my work.

Sunlight, heat, and UV kills all subwoofers. After 20+ years, you would be lucky to find a good one that's original.
