[QUOTE="keep_hope_alive, post: 7343532, member: 576029"] that's the point. the shield on the RCA is what you need to ground. an equal solution is to ground the outer rca jack on the HU. when the pioneer diode "pico fuse" pops from someone messing with RCA's while the HU is on, you lose continuity between ground and the RCA shield. as a result, the amp receives a "floating" input which results in a potential difference between HU ground and amp ground. what do you think "grounding the rca" entails and why you do it? you never ground the center pin, that has the audio signal and could damage the HU output. if the center pin becomes grounded, the output won't work. that's why you measure your RCA continuity before you install them. measure along the length for both pin and shield, and measure between pin and shield to ensure there isn't a short. some come from the factory with a short. poor quality control. you only need to install a couple bad RCA's before you test them first.
