Since we're on the topic of sound and speakers...

I've got a couple ~25 year old speakers, massive things, each connected to the stereo with about 15 feet of wiring. Every once in a while, the left speaker will halfways cut out, put out a lot of static, and then for no apparent reason, fix itself. Any ideas what the problem could be?

Could be a lot of things. Could be you got some critters in residence inside like Possum did, or maybe your speaker wire is being bumped and it's affecting the connection, or maybe the speakers are not adequately shielded and are being affected by line noise or RF noise, which could be coming from any of the surrounding electronics. Cell phones are notorious for this, when they are negotiating a handshake with the tower. You can get about a half to full second warning that your cell phone is going to ring if you leave it beside an unshielded speaker.
