Installing a Car Audio Capacitor with REM Terminal



Purchased yet another generic Chinese-made product this time a necessary upgrade to mobile audio system. The device is labeled as Boschmann 2.0 Farad car audio capacitor. It has a 3rd terminal labeled as ACC or REM in some other products and must be connected to the head unit's REM terminal as well to turn the device on. This capacitor works automatically and does not need pre-charging. It turns on and off just in time together with the head unit and subwoofer amplifier.
