Well, today I replaced a 4700uf and two 470uf filter caps in the amplifier that were out of spec and the interference on my radio has completely stopped. And on top of that, the low-level motorboating from the amplifier's subwoofer has stopped, too.

Edit: I had tested this out while plugged into a different circuit from the radio, and had good results. However, after putting it back in the same room (and plugged into the same electrical power circuit) there is still a bit of RFI. Fortunately, there is an outlet from a different circuit a couple feet away, and the noise is gone again.
It's not how bad you mess up, it's how well you can recover.
