I pretty much have the same system as i started with, but i expanded on it. My first system was 1 10" MTX 4000, a Promax 150 watt amp (you wish you had one,lol) a JVC 40x4 tape deck, JVC 12-disc changer, pioneer 4x6's, and pioneer 4x10's. Since then i have added another 10", upgraded the amp to a MTX blue thunder pro 150x2, and got my new alpine deck. Man, the deck switch alone made a huge difference.
