Has anyone installed additional Speakers in the very back? If so, was there speaker wires ran there already or did you have to run it?

While I have not done what you are asking, I can tell you almost certainly that speaker wires are NOT there! But running speaker wire is the easy part. Will you need additional amplification? Where will the input feed come from? Will you run speakers in parelle from the rear door speakers?

Where are you thinking of putting speakers? Probably better bet to do what some of the rest of us did and upgrade the rest first then see if you need more. Dash upgrade and doors. The standard speaker are really poor.
