add sub & amp to factory navi?
 

Im not sure whats behind my navi unit and I dont really want to start ripping my dash apart just yet so hopefully one of you guys/gals knows whats back there.

What I need to know is, what connections are in the back of the navi unit? RCA? Secondary Video? Anything other than Honda Plugs?

I have a 12" Memphis Ma-Bell, 1200watt amp (getting second Ma-Bell soon) & a 1.5 Farad Cap (going to 5 when the second Ma-Bell gets here) Im wanting to put in the trunk.

Any help or site to look at is great! Thanks Everyone!
