In case you want to hack into a classic car radio to make it MP3 player ready, The AMC Forum shows you how to do it.
For under $100 in parts, you can add an MP3 input to an old AM/FM radio. You can attach a CD player too and still use the knob on the radio to control volume.
We have no idea if this works or not, but Lifehacker seems to think it’s great.
