Anyone know what these are?

I was fitting the grom Bluetooth module in the back of my coupe and noticed what looked like an amplifier? Does this come with the Hifi system as standard?

Also any idea what the other two modules are to the left? They have coax cable running between them so assume some kind of gps/phone?

From left to right: Bluetooth (ULF) module, telematics module, stereo amplifier

Great, thanks. Had no idea my car had an amplifier, needless to say I am very underwhelmed by it lol

Haha yeah you should hear a car without it then! My first Zed didn't and it was pretty weak!
