I have a PCX-5F POWER ACOUSTIK 5-Farad Digital Capacitor and after i turn the car off it stays on and sometimes when the keys not even in the ignition the cap stay on. why is it doing that?
It stays on even after an hour. sometimes after a few minutes it shuts it self off.

How many uf is indicated on the capacitor.It will show a number ie 10uf. If the rating on the capacitor is more than 5uf or less than 3 uf then the capacitor is failing. 10% variance is acceptable. Most electrical wholesalers sell capacitors and cost is around $20.00 or so.
it's like a battery. you run it in parallel (run power from battery + to capacitor + then from capacitor + to ampplifier +) battery, capacitor, and amp each has its own ground (black or -). you don't need a remote wire. it only stores electricity until the amplifier needs extra juice (so your headlights won't dim).
With BIG wires from battery to cap and then to your amp.
Good idea to put fuse or fusible link between bat + and the cap. Protects against fires.
If one wanted to be safe from starter motor transients I would gate the + power lead with a power relay between the battery and the cap. This relay should close when you are in run or accessory position of your key switch. I recommend this as there are so MANY dead car audio amps. Just search for them on here! A bunch of them MIGHT be caused by inductive transients during starter motor shutdown. Note the inductance is in the grounding wire from teh battery to the engine/chassis.
Cap is hooked up wrong, should shut off after a certain amount of time and reactivate with the ignition hot wire. If it's draining your battery continuously then you should look at the wiring.
You hook it up in parallel with your amp. You'll see a and - on the clear plastic cover.
Hook a wire from your amp or positive to the capacitor
Hook another wire from your amp - or negative to the - on the capacitor.
That's it, you're done.
If the plastic cover is missing, or painted over, with the neon tubes at the top, and the connector/display end facing you, the right side is the left side is -.
Use to independent grounds always better that way. Better full field for power and less distortion. I like to use 4 guage or lower like 0 guage for high powered systems. Good luck, thanks for using FIX YA
