Radio and Speakers
Start your tailgating party off right and keep the action going all day long with a high-quality sound system. Sure, you could just run your car radio all day, but you may find your battery completely depleted when it's time to head home. A separate sound system not only offers adequate volume levels so your music can be heard over noise made by rowdy fans, but it is also more likely to produce high-quality sound.
A simple stereo and basic speakers allow you to keep up with all the pregame action and team news leading up to the big event. If you plan to tailgate for hours or days leading up to the game, consider investing in an MP3 player docking station with high-quality speakers. You and your friends can switch out your iPods every few hours and take turns playing DJ. Don't forget to play your team's fight song at least once an hour!
