installing indash tv and EQ??

Hi i am about to install a kenwood execelon dvd indash tv and a Eq in a 2001 nissan maxima. If anyone has ever installed something simliar to this in a maxima can you tell me how you built or obtained a custom faceplate. Also how do i hook up the Eq. i know how to plut it into the power ground and remote but how do i get it to actually work with my subs.

the EQ is hooked inline, the RCA wires come out of the CD player and into the EQ, out of the EQ and into the crossover or amp(s). Only problem is, the EQ will not work on amps built into the deck.

this is jsut an assumption, but he said subs so he most likly has external amps.
