The verdict is still out on the XD's I havent really decided yet. for the price they seem awesome but this is my first real system using 10's I have never been a huge fan of 10" bass but I couldnt fit anything more in my single cab lol. They definately take the power but I havent poured it to them yet cause I have to install this damn battery when I go buy the 0 guage to do it. More than half volume either shuts off my truck or my amp and I know I will burn it up if I push it on low power. I just got started about two months ago on this one.
