as far as the different colored amps, it actually looked much better when the whole trunk was done vs when there were no finished panels. Im glad we put the black amp up top becuase when you open the trunk and stand and look at it without bending down, you only see the lower black portion. Its definitely bearable. Also, when you try to color match stuff, and its not EXACT, its even worse than having 2 totally different colors. im happy with it
