Right rear speaker very quiet

[I Like Waffle]

Bros, i installed a new HU in my GFs car today. I noticed an issue when playing with it to make sure the fad/bal was right. Im NOT sure whether or not the issue is with the HU or not though, i could have just noticed it. The right rear speaker is very quiet, so quiet as you can only hear it barely if its on max vol.

Its not the speaker, and the wires at the HU are good. I have ran new wires from the HU to all 4 speakers so the wiring through the car should be good. The HU is a pioneer DEH1600. What else can i check? Does one channel of the internal amp halfway burn up somehow? Im gonna pull the HU back out and verify the resistance of the speaker at the HU itself to make sure nothing crazy is going on down the wire somewhere.

Just figured it out, apparently something is wrong with the radio. Oh well, i got it for free. Ill just pick up another one for it. Sounds great on the other 3 speakers, lol
