I take sound quality over features and pay close attention to reviews on decks.... I have had 3 Kenwood Exelon's for the last 3 cars Ive had because of it. All of which I replaced the stock speakers and added subs. The reasons I chose the exelon is: Price (very cheap), seperate sub settings (a must), LPF/HPF of front/rear/sub. Bass freq/EXT, Full mid control and freq, Full Treble control and freq, USB on front, AUX on front, and a few more I am sure I have forgotten. I havent replaced the stock speakers in the xfire yet but I have kicker tweeters on the way. I just got my 2 Kicker 10" comps with a ported box in yesterday and once again.... Not one complaint with the deck. Even the old models I had in my older cars were really top of the line. Kenwood used to be crap, but they have really managed to step their game up.
