suda695 Posted October 24, 2015 Report Share Posted October 24, 2015 Just finished watching the Truth about RCA's video on the D'Amore YoutTube channel. Just wondering, I can understand how the differential input would receive the two signals and double minus them to get a clean signal however wouldn't this only happen if the car's head unit outputting the signal had a differential output and sends that out of phase signal? As far as I know the majority (if not all) aftermarket head unit's have their shield end of the output connected to ground. So my questions are: at the amplifier input wouldn't the "shield" wire in a twisted pair just have noise in it as opposed to an out of phase signal with noise? If this was the case, how does this affect the resulting signal? Also would a single ended RCA work better than a differential in this scenario? Or would the fact that the shield end is getting all the noise and the pin is getting no noise work out to a lower quality signal once it has gone through the final stage of the input? Cheers, Ben. PS. I'm a aware of the modules you can connect in line with your RCA's to convert them to a differential output. My question doesn't involve them thanks!
