I'm connecting my amp to my head unit with Monstercable Interlink 201XLN RCAs. I need to cut one end so I can splice it into my factory harness in my trunk (leads to my head unit for the HU outputs) and the other end of the RCAs will plug into my amp. These RCAs are 'balanced' with a (+) & (-) for each channel. Here's my question, Monstercable has a 'drain' wire running the length of the RCAs, where do I connect this wire when splicing into the factory harness?
TIA
