whats up guys. im the first to admit, while i know my way around cars fairly well i dont know anything about stereos/systems. im looking to upgrade my evos a shade. im not big on the box idea, it weighs too much and takes away trunk space. if i was to put a sub it would be in the side of the trunk, a custom thing. anyway i hear that the factory evo speakers are decent, just the had unit sucks. any suggestions on how to beef up the factory system without going too overboard with $$$ and weight. i dont even necessarily need a sub just some nice interior speakers to make it sound better.
