I will say that this isn't really something you need to worry about at all.
When trading in to a dealership, they could care less. The cost for them to replace the speakers and amp...if they even do...is next to nothing.
Do what you want to the car. Heck, just the other day a friend traded in a car with holes in the a-pillars where they had mounted tweeters...they got exactly what the car was worth, nothing else.
Friends who work at dealerships verify this as well.
And if selling to an individual, they would prefer the upgrade over the stock stuff.
