What material can I use to surpress a magnetic or electromagnetic field?

I am putting subwoofers with a mdf enclosure in my trunk of my jeep and am going to integrate a computer system in my car as well. The only concern is that its my understanding that the subwoofers emite an electromagnetic field and it could endanger any sensitive storage devices on the computer like the hard drive or ram. I was wondering what would be the best way of preventing the damage that might occur. The easiest solution I was considering could be a rubber lining inside the mdf box to surpress it, it might differ the sound slightly but it could safe guard my system. Or would be better to keep the pc at a considerable distance?..

install the pcaway from your woofers, or use shielding to ‘insulate’ the pc from the rest of the car
