Details:

Thru harness fits perfectly and works fine. I am including an 8ft pair of Basics car audio stereo RCA cables unopened and 4 female to adapters help with extending your the location. This 6ch HiFi 676 harness is used to replace the OEM front/rear/woofers with a 6-ch balanced inputs aftermarket. This part is not returnable, so I want to sell it someone who could use for their own install project.

Example of the direct aftermarket replacement for OEM HiFi is JL Audio XD600/6v2. Alpine PDX, Match, Helix, and Arc Audio amps are balanced-inputs compatible as well. OEM HiFi HU output full range signals. I bought this harness to integrate an aftermarket my 2011 BMW 328i.

Use Y RCA adapters not included for multiple balanced-inputs amps.
