I covered that in my previous post: Crutchfield isn’t to blame for this situation any more than CentOS is for the UEFI+SB situation. Blame Ford and Honda, Intel and Microsoft. > then there's the wiring, you have to make up an adapter where one end is car model specific, and the other end is stereo specific. and if the car has more than 4 speakers, life gets more complex, you'll probably need to add in additional amplification. The skills and equipment you need to do this are directly analogous to those needed to repartition a Windows box for dual-boot. The two cohorts are probably about the same order of magnitude in size, and somewhat overlapping.
