OK -- time to upgrade the sound system. I already know about the speakers, but what about amps? Who is happy with theirs? Where do they go? How difficult to wire? I am NOT an electrical genius, but I know what sounds good, and it is not the stock setup. Hep me! Hep me! This weekend's trip to Austin finally convinced me that the current set up is not good for highway speed(80 mph) and wind(in my face).
