bjc, I dont know if its the exact same mod, but I will say that the sound now is much much fuller than the sound coming from the speaker out into the amp. I dont know that Id be keen to pull the icc apart, but yeah, if you want to attempt it I'd be keen to see the results, the big bonus (to me, which may not be to others) is that they have also given me a remote out to power up the amp as well as a separate subwoofer out line and they tell me that I can do away with the factory amp etc altogether. Putrid fruit seems to sound like he knows whats going on and they seem to be fairly easy fixes if they work in your case so I'd give them a go first if I were you, (I already tried what he suggested a few days ago). In anycase, goodluck with whatever you try.
