Hi, To my knowledge, this head unit (Sony CDXF7000) uses individual 52 watts amplifier (X 4) whose output to the speakers require that none of the speaker wires be grounded or crossed/shorted. Please check the speaker wiring with the use of an ohmmeter (or a multi tester) with all the speakers temporarily disconnected. Verify that none of the 8 wires reads 0 ohms to body/chassis ground or to any of the other wires. As you have checked the wires area: front left > + red & - white/black stripe; front right> + gray & - gray/black stripe; rear left > + green & - green/black stripe; rear right > + purple & - purple/black stripe. Rewire should it be necessary. If the wiring fully checks out, it may be that you have a fader component failure inside the unit (though honestly rare). You can also check if there is no bridging modifications done; converting your 4 amp-4 speakers original design to a bridged 4X52=2X100watt amp to 4 speakers paralleled to 2. Another area you can check/try is by varying the DSO settings - 1,2,3,off. Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.

When the rear output setting is "rear s/p:SW", you cannot adjust the front rear spreaker balance. Go to the rear speaker output from function and select "rear sp/full".
