Review on 🔊 Enhance Audio in Your Ford Vehicle with Metra 70-5701 Premium Sound RCA Wiring Harness by David Cash

If you have an Alpine Stereo you need this set of wiring harnesses. The cinch is plugged into the Sub Out socket on your new main unit. Most head units only have one sub jack, so only use the white jack. The largest connector actually only has one pin (for the power antenna), so if you want you can remove the pin from the connector and plug it in the same spot on the factory connector and save some bulk. There are two amplifier grounds, so I combined them all into one ground point. I would also suggest to buy [Axxess Interface AFDI-5V Ford 12V to 5V Step Down] so there is no loud popping sound when starting the car. If you're howling an alternator, this can be fixed by grounding the head unit to metal instead of grounding the wiring harness. I have been using Metra harnesses for a long time and can attest to their quality.
