radio in glove box?

If you have a smart phone or any type of player like an IPod or MP3. All you need is an amplifier under your seat and some speakers. You use an audio jack from your phone or devices headphone jack into red and white RCA's plugged into the input side of an amplifier. Make sure to connect the blue remote wire from the amplifier to either a keyed on/off fuse or on a switch to turn the amplifier on and off.
With this setup you can play anything your device can play. I use the Tunein radio app to play radio stations and I always have playlists and albums of music saved to my phones drive as well so I don't always use data.
