[QUOTE="keep_hope_alive, post: 7995172, member: 576029"] shield should be connected to chassis on both ends (HU chassis and amplifier chassis). this connection is usually inherent in the equipment, so no extra work is required (ahem**Pioneer**) lack of a ground connection on either side can cause noise. this can happen inside the RCA - which is why i like a two-piece that i can open up and inspect connections. you can also use a DMM to measure continuity. in some cases, grounding only one side (amplifier side) is beneficial. depends on how the HU outputs are configured. for example: on my older Alpines, i could have the RCA shields ungrounded at the HU and have no issues. on my new Alpine that causes an assload of noise.
