The Scuderia Audio 400 Watt OEM Super Hi-Fi Upgrade Amplifier for 575M Maranello fits the following Ferrari models including but not limited to, 575M Maranello

Power is the key to a great sounding car audio system. Scuderia Audio has designed and manufactured an amplifier with the same size and connecting plug as the OEM 60 Watt ASK booster that is mounted on the right side of your trunk. The difference is that we have mounted two high end Mosconi 200 Watt amplifiers inside of the case. You simply unplug your 60 Watt booster, remove it from the trunk, bolt in the new 400 Watt amplifier and plug it in! It couldnt be easier.
In 10 minutes you can go from a cheap, 60 Watt system with no bass to a high end, 400 Watt sound system!!
