[QUOTE="The Tall Man, post: 211591, member: 547685"] Hello, I have a BMW head unit with "BALANCED line outputs". The outputs currently go to a stock amplifier, that I want to keep. Two questions: 1.) What is the impact of "tapping" these line outputs? I want to tap them and send them to a converter (to RCA) and then to an aftermarket sub amp so I can add a subwoofer. Will the signal be cut in half to both sub amp and the stock amp? Will I notice lower volumes from the stock amplifier? Should I worry about damaging the head unit (it will see a different load when tap the lines)? 2.) What is the difference between BALANCED line outputs, SPEAKER level outputs, and RCA outputs? Thanks! TTM [/QUOTE]
