When it comes to marine stereos, there are a few key features that set them apart from regular car stereos. For one, marine stereos are built to withstand the harsh elements of being out on the water. They're usually waterproof and salt-resistant, so they can stand up to splashes, spray, and even submersion. Another big difference is that marine stereos often have superior sound quality. This is because they're designed for use in open spaces where there's lots of background noise. So, they tend to have more powerful amplifiers and speakers than car stereos. Finally, marine stereos typically come with a lot of handy features for boaters. Things like Bluetooth connectivity, GPS navigation, and SiriusXM satellite radio can make your time on the water even more enjoyable.
