I love my new MS but regret the decision to go with the basic sound system. The basic sound is muddy and, IMHO, just plain mediocre compared to the rest of the car. Feeling penny wise and pound foolish. I am now looking for an aftermarket solution to make the audio as stellar as the rest of the car. Would very much appreciate any recommendations for audio installers in Miami/South Florida, preferably one that has worked on a couple of MS's before. Many thanks, in advance.
