Radio/Speaker Wiring Question
 

I did a search for "radio" and didn't see this topic, so here goes...

I have a 2007 Accord which, when I input my VIN on the CarFax web site, is described as a "value package."

This car is a lease, andcame from the dealer with front speakers, but no rear speakers, although the radio has a "fade" control, where I can turn the knob from "front" to "back" and of course, when it's on "back" there is no sound.

If I buy the rear speakers made for the Accord (the holes are in the deck...they're just covered right now, does the wiring harness that runs through the trunk already have the speaker wires, or will I need to add wiring, too?

Thanks,
