I am thinking about getting one of these. I would like to know whether the mopar subwoofer routes the low freq signal away from the full-range speakers, or do they still get the full signal. I am hoping that the low freq is re-routed so the speakers distort less. Have you heard a decrease in distortion / increase in clarity after installing the subwoofer with stock audio? Yes, I know about adding amps, replacing speakers, changing head units, etc, but I am interested in if/how this subwoofer improves the stock set-up. Also, what seems to be the concensus on the best setting for the sensitivity adjustment (lowest, half, full, etc)?
Thanks.
