amplifier

Just purchased a 2014 wing with csc trike kit. I noticed in the back trunk in the bottom hole there is a Panasonic amplifier that does not look original. What does it do, and there seems to be a UBS plug attached?

On my 2015 that is a factory amp. The USB plug can be used to plug in a flash drive and also you can plug in an IPOD and use it with the handlebar controls.
