    I know there are tons of threads on this already, but they all day different things.

    Here is my setup:

    Deck - Sony CDX-GT630UI
    Amp - Kenwood KAC-7204
    Sub/Box - Image Dynamics CTX124/Tacotunes box (both purchased from Tacotunes)
    Front Door Speakers - Kicker 6" (not sure of model number) stock tweeters
    Rear Door Speakers - Stock

    I have HPF and LPF options on the HU.
    On the amp I have a switch to select either HPF/LPF/OFF. There are also knobs that say Gain and Bass Boost. What is the proper way to set all this up?

    I'm assuming you're running the sub off the amp's bridged channels and the door speakers off the headunit. If that's the case do the following.

    On the headunit use the HP and set it at 80hz.

    On the amp set the LP at 80hz.

    Done.

    That is correct. Do you mind explaining to me why or how you came up with this? I'd like to learn.

    They say that 80hz is about the point that most people can not localize a speaker. The idea is that you'd want to not know where the sound is coming from with respect to the sub (since it's behind you). 80hz is always where I tell most people to start. If you have a strong front stage (door speakers) you can go lower if you want.

    This basically puts all the bass frequencies on the sub and keeps the door speakers from doing too much work outside the range of their capabilities. It also keeps them from overlapping in the frequencies they play.
