Alright, I'm planning to change the radios in both of my parent's cars soon, and I'm debating whether to buy them at any electronics store or from Crutchfield. Any electronics store (e.g. Circuit City, Good Guys, etc.): in this case I have to buy the parts & stereo separatelly. From Crutchfield: they add the customized parts (e.g. harness, wiring, sound controller for factory Premium Sound) for the car when I order the deck at no additional charge. Your input??? please choose.
