We recently bought the car listed above with a aftermarket stereo. Now my issue is my passenger side front and back speakers don't sound.

There is an amplifier on the left rear strut tower that drives the right-side speakers, I would retrieve the wires and run them directly to the aftermarket unit. Here are the radio wiring diagrams so you can see how the system works and which wires run the right-side speakers. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
