Answer
Hi Ashley,

Sorry about the delay in answering your question--it seems to have slipped through the cracks.

Sometimes these vehicles are equipped with a factory amplifier.  If you have the stock amp, it's not enough to connect the speaker wires correctly; you also have to activate the amplifier before you'll hear any sound.  The amplifier, if equipped, will be mounted under the center of the rear deck, between the two rear speakers.  You can see it by looking in the trunk.

Here's the factory wire colors:

Left front (+) tan
Left front (-) gray
Right front (+) light green
Right front (-) dark green
Left rear (+) dark brown
Left rear (-) yellow
Right rear (+) dark blue
Right rear (-) light blue

If you have the factory amplifier, you also need to connect the white factory wire to the blue/white wire coming from your new head unit.  (If the new deck doesn't have a blue/white, use solid blue).  In fact, you should connect this wire even if you don't have a factory amp, because it also activates the built-in antenna amplifier, and connecting it will give you better radio reception.

Hope this helps!
