Every shop loves to show off their most wild and powerful projects, but here at 500 MADNESS we are extremely proud of our full-service automotive center. We handle everything from oil changes, engine service, installation of aftermarket products, even a list of scheduled tune-ups you should complete. You can use the menu options below to look a little deeper into our Service Center and find exactly what you need for your FIAT 500. Also be sure to snoop around our store and discover all the items that can be used to accessorize, customize, and personalize your 500. Then your next step is just to stop on by!
Are you looking to replace your factory sound system with something custom or simply wishing to improve the existing sound of your FIAT 500?


We can help with your needs. We have upgraded many FIAT 500 sound systems and have a large variety of options available to fit every budget and need. We offer installation on premises and stock a large selection of aftermarket head units, amplifiers and speakers.

Our prices are very competitive and since we specialize in FIAT 500s we know what equipment works best on the 500.

If we have it, we can install it for you while you wait. Give us a call at 888-993-7552 (US Only) or 562-981-6800 for more information or to schedule your appointment.
