Hi all.
Just bought a beautiful black 2011 f150 super crew 5.0
I don't have the navigation and don't think I have sont Speakers, no sub under the back seat. I need a little bass! So what are my options for adding a sub (or 2)? What will I need to connect it all to the factory head unit?
Thanks!

 

You could look for a deal on a Kicker Soundstage or Soundgate or go with an aftermarket box and amp. I don't recall the pinouts but if you go aftermarket amp there is a plug under the passenger side rear seat for a sub. You should be able to get a line level signal from it.

 

I bought this on Amazon for a little over $400. Well worth it for me.
