This setup made adding an amplifier to my 2026 F‑250 incredibly easy. The factory‑matched harness adapters were a huge win — true plug‑and‑play with zero cutting or splicing of factory wires. Tapping the door speakers and running that signal through the KeyLOC gives me a clean, strong output with absolutely no bass roll‑off, fixing the biggest flaw in the stock B&O system. The product arrived well‑packaged, and the online install videos made everything straightforward. Highly recommended.
