I love these little devices. I've bought at least 10 so far. They work great with all types of sound systems. I make cool ghetto blasters and even use them for my store radio. For even more adaptability, connect a Bluetooth adapter. You can power them with a simple 12V 3A power supply or use the built in 3A fuse and connect to a 12V battery. I like to use motorcycle batteries because of the size and amp hours. A fully charged motorcycle battery is enough for a whole day of river rafting in my canoe.
