This is a wiring diagram for a nissan frontier. It may or may not be helpful

Are all speakers off?
If so, then the head unit is the issue.
If we're only talking one speaker off, then check the wiring to that speaker.
You can connect an AA or AAA battery to the speaker wire, and check to see if the speaker moves. If it does, then the spring and speaker are fine. It's the head unit which is faulty.

open trunk and look very carefully at the copper colored wires on bottom of rear speakers and make sure they are not contacting speaker frames and shorting out.often occurs whe stuffing large items in trunk.this will shut down all four channels so radio is not damaged.hope this helped.

i would check to see if the fuse to the radio amplifier is blown. look in your owners manual for the location of the fuse. if the fuse is good you may have a bad amplifier. all the radio wires that go to the speakers run throught that part.

i had this i wired my own **** up

Here is the wiring diagram for a 2004 Sentra. I hope this helps.

I have the same car...04 nissan sentra....with the exact same problem....left side speakers just quit working. I still do not know what caused the problem, or how to fix it. I know it not the wiring, it is a defect within the stereo.
