I am a newb on the car audio thing, but I am about to upgrade the sub in my accord. I was thinking about adding a amp and finding a nice sub that will fit in the hole of the existing 'sub.' I know that I have to disable the anc by disconnecting the module but I wanted your suggestions/opinion in this sub that I picked out.Will this sub fit in the existing hole? Also what are good brands of decent midlevel amps? One last question! When you people connected the amp in your 9th gen did you use the audio feed of the existing sub wire or did you use the left or right speaker wires?
