Marc, Thank you for your review and feedback on our products. After reviewing our previous conversation, we are confident that there is another issue occurring with your installation. The wires you referenced have been verified to be in the correct locations, and their colors match the OEM wiring diagrams. It appears that you have attempted to determine which wire colors carry specific speaker signals, but your conclusions do not align with the OEM diagrams. The issue you experienced with ground feedback most likely disappeared because you reversed the ground wire. Your comment regarding the switched positive and negative wires is incorrect, and we ask that anyone else reading this please disregard that statement. All of our products are designed based on OEM wiring diagrams. In some cases, the wire colors may differ from common expectations. For example, in this particular setup, the positive wire is black while the negative wire is red. This is how the OEM designed it. While most people assume red indicates positive and black indicates negative, that is not always the case. Regarding your comment about the RCA plugs being switched, this is also incorrect. The RCA connectors are clearly labeled according to their respective inputs—RL and RF—which match the OEM diagrams. Although the RCA colors may differ, color does not determine the signal being carried, as is also evident in the OEM wiring. That said, your review did help us identify that the center speaker output was reversed, which was indeed an issue. We appreciate you bringing that to our attention, and we have corrected it in all future harnesses. Thank you again for your feedback and for helping us improve our products.
