You could run a dedicated power wire, and its still connected to EVERY other electrical component in your car no sir, you are the retard… you obviously dont have any sort of comprehension skills. YES im aware that its deriving its ORIGINAL electrical current from the battery which is powering the entire vehicle… im not a fuckin drooler. the capacitor is only helping the subwoofer amp when hooked up the way i described though. it receives its power from the battery and is “stored” in the cap… if the cap OUTPUT is only hooked up to that ONE amplifier… (hence isolated) it only allows the capacitor to discharge to that amplifier… which is the ONLY place you’d need a capacitor… NOT for the rest of the electrical system… or are you THAT dense? --- _[View the full topic](https://forums.speedlife.net/t/building-a-new-system-have-some-questions/241394)._
