im using a power acoustik capacitor. i've read time and time again that capacitors either turn off with a remote wire or when the power gets low, but mine never turns off? i believe i wired it correctly. positive from the battery to the cap, then the cap to the positive on your amp, then ground to capacitor then to negative on your amp. i turned my car off for about 30 minutes but it's still on. anyone??

Are you talking about the Digital Volt Meter that is mounted to the top of a capacitor? If so it may remain on for up to an hour. It pulls very little current. Leave it on one night and see if it is off in the morning. It should not run your battery down. After all you do have all of the super duper extra current of the capacitor.

Capacitors do not "turn off." But like described above, if you're just talking about some sort of display, that's up to however it is designed.

Does the cap have remote wire hook it up and can connect to remote wire? Digital meter on the top of the cap are useless. Its made just for look and make people get attention . I had one Rockford Fosgate cap and I remove it the top and still can use it. The cap only need negative and positive. My car battery never died.
