eclipse is popular and great stuff in the US, just like how clarion and alpine is

pioneer is pretty good too, but really im not the ICE person, so i have no say. but i know SONY is not want. comparably, pioneer has MOSFETs, not sure bout eclipse. but judging on pioneers features, take pioneer, no regrets, especially with ipod expandability

ive owned a kenwood hud and pioneer speakers, it worked great
