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.

Ha, I was going to mention that possibility.
I have a Kindle Fire touch screen in my car, so I can even sit in the house and transfer music to it wireless.
Radio stations are everywhere online and I can use my phone as a hotspot if I really wanted to listen to internet radio, but I never do hardly since the Kindle has 8 gigs of memory for that.
Mostly just the music loaded to the Kindle is what I listen to.
I also added a 12 to 5v regulator system to charge it as the car runs, but it can also play for hours on it's internal battery and not use the car battery at all when the car is not running.
