[QUOTE="retrojordans, post: 7249789, member: 630134"] I mean I'd be inclined to say (without running a diagnosis and or taking it apart) that by deduction if there are issues with parts of the radio e.g. the lines, the opening mechanism (which could be the gears or motors or any number of things) etc...There are probably other issues with the radio concerning the built in amplifier circuitry. If something happened to the radio to make the lines on the screen, and affect the opening motors/actuators it is totally possible other things could be affected such as the internal line driver. That head unit puts out 6.5v pre-outs and the circuitry producing those voltage levels would be what affects the volume, a lowering in those would require you to re balance your amp's gains to match the head unit's sagging voltage. I recommend testing the pre-out voltage of the head unit then re-matching that voltage to your amp's gain, and possibly adding an external Line driver regardless of the results. [/QUOTE]
