My main objective was to be able to easily control volume for the tower speakers and the cabin.
When i first started i really did not know where to install it I tought that i would share a picture in case it helps someone. .
I just installed a cheap equalizer. (45$) I made a box in wood, painted with bedliner paint and i cover it with the same vinyl that i used for the seats.
I wanted the volume knob to be easily accessible so i decided to install it on the left side. It turns out that it’s not in the way, even if i am 6’3 My knees clear it easily.
i was very surprised to find out how much of a difference it does for the sound.
