Question about Sony XM-404EQX Car Audio Amplifier
If the other channels put out only a small amout of sound compared to the rh channel it is possible that the preamps might be buggered. To test this get one set of outputs from your headunit and connect them to each channel one by one and the same on the output side with a speaker. If the problem doesnt exist then, it could be your head unit that is at fault. check the settings in your head unit as well you might have accidently changed the fader settings.
Other than that drop it in for a quick bench test at a local car stereo installation place and they should be able to offer a quick and cheap if not free diagnosis of what the issue will be.

Cheers mutleys. I've not installed it yet and am bench testing it with an i pod as source into the phono inputs and similar speakers into all of the outputs. I suspect that there's a problem with a gain transistor in the pre amp stage of that particular channel but I'm no expert. As all of the gains and equalisation pots work and the volume is there I hope that it can be fixed cheaply, I was hoping to use the front and rear outputs in bridged mode to give 80 rms into 2 channel driving some big old Pioneer 3 ways. It'd be a pity to junk it.
