I'd love to know if anyone took the stock head unit apart and found a pre-amp signal that we could tap into. There are probably a handful of people on here who replaced the head unit and have no use for it...
Am I misremembering, or does our head unit have a lower volume mode? (My LG TV does)
If it does, maybe that's the mode to use with an external amp....sot of like a pre-amp signal (more useable "volume steps" anyhow).
