Wow, thanks for the overwhelming response, guys. So it looks like I fucked up in choosing to install the speakers. It seems like putting the factory back will be my best option since I am going for overall sound quality rather than volume. I could get my stockies up to just where I wanted them and they sounded great, even enhanced the subs in a way. When installed, my Dad and I cut the factory input off and attached the Kickers with crimps that were in the box. If I wanted to put the factory back in, is it going to be a pain in the *** or would I just have to undo the crimp and redo it with the factory again?
