It's tailgate time of year, so break out the grill, crock-pot and, of course, outdoor speaker. You can't have a good party without your favorite playlists (and maybe even a little karaoke), which is why I've rounded up some of the best outdoor speakers for fall. And having tested a ton of these things, I've got good news: It's hard to choose a bad one. Most are waterproof (or at least water-resistant), meaning a few splashes, raindrops or even snowflakes won't fry the electronics. Several are parking lot-friendly as well, able to repel sand, dirt and the like. And best of all, you can score some great October Prime Day deals if you act fast.
