Monster has teamed up with Lamborghini to create a special Monster version of the Lamborghini Veneno Roadster with a complete audio system supplied by the company.
The speaker system, which cost around $50,000 to install, is a drop in the ocean compared to $4.5m price tag for the car.
The surround-sound speaker system was fitted in just seven days by Findlay Customs in Las Vegas with the help of Lamborghini technicians and includes a dedicated Android-powered touchscreen interface so you can control the music - we couldn't resist, we listened to Blurred Lines by Robin Thicke.
It sounded so loud that our legs rumbled with the vibrations from the subwoofers installed in the driver and passenger footwells.
The Veneno Roadster is a beast of a machine. It can go from 0 to 60 in less than 2.9 seconds and has a top speed of 220mph.
Inside and the interior and the two bucket seats are made from Lamborghini's Forged Compsite with a carbon-fiber CarbonSkin that clads the entire cockpit.
Oh, and only nine will be produced.
