My JBL PB12 sub amp crapped out. I've heard they are known as a POS. JBL didn't respond to my questions, so I guess I need to replace the amp plate. Anybody know what will fit, and where I can get one? Thanks very much.

You can look at these and see if any might fit. I used one of them when my subwoofer amp died.

1st of all, mad props for working with what you got. having said that here are a few little tid-bits that will help. one of the the big misconceptions is if a speaker says 100 watts max. that you should only run up to 100 watts, actually what you don't want to do is under power a speaker. If it says 100 watts, you would be safer running 300 watts as long as you have a good ground and no engine noise.In other words, good clean power, heres why.simply put a speaker produces sound by the voice coil moving in n out of where it sits inside the magnet on the back of the speaker. every time it gets thrown out the magnet is the mussel that pulls it back, if the magnet is under powered it cant pull the voice coil back fast enough so it jumps out too far and thats how you blow a speaker. Now especially since you're using a home audio speaker that probably has a smaller magnet than a car audio speaker would. also being that a sub has a longer throw of the voice coil than a mid or a tweeter theres greater risk of blowing one by under powering it rather than overpowering it. also if your deck has a numerical LCD for displaying the volume, anything over 25 is a distorted signal if it displays db's 0 is the highest you can go without distorting the signal Now to answer the question you asked... yah it should work fine. Good luck.

An alternative might be to replace the sub system w/ a powered sub woofer self contained unit. I have a surround set up in the family room in the basement for the big screen (rather large room) and spent $100.00 for a powered sub from Radio Shack and it will rattle all the walls and windows in the entire basement if you want it to. Cheap, economical, good quality solution to your problem.
