I have no issues hearing my radio on the highway going triple digits or at full throttle, its a Fusion MS-RA205 Marine stereo. It was installed by Vintage Motorsports and I had them wire it up so I can switch it on when the car is off. The batteries in these cars are small so I dont use the radio alot when the car is off but it is a nice option to have. If you want to know more about the components then PM Cashburn here on the forum, he and his brother installed it for me. I tried posting some pics but they failed for some reason. Here is a link to pics of my Cobra with the radio in it.
