The 1 farad capacitor is something added to current hungry systems to help keep the supply voltage at the proper operating level.
If your amp does not work after putting one in your system, but it worked before you put it in, you most likely have it installed wrong.
The capacitor should be put in parallel with the main +B voltage of the amplifier. That means you would connect the positive side of the capacitor to the +B voltage supply of the amplifier and the negative side of the capacitor would go to the chassis ground.

If you have it connected in series, or inline with the +B voltage supply, the capacitor would be blocking the voltage to the amplifier.

Without more information on your problem that is the best answer I can give you.
If this does not help, please supply more information and I will be happy to help you further.

Are the capacitors suppose to stay lit and will it kill my battery?


It should be turned off with the key. If it continues to stay on it is installed incorrectly to a constant power source.

How do i charge it


To charge a capacitor:
connect it to a power source that has less voltage than the capacitor's tolerance.
Wait for it to be balanced with the power source's voltage.
The source must be DC.

It's beeping when turned on. Why?


I have read that if the polarity is reversed, or the connections are backwards, the Capacitor will beep. If this is not the case, it may need to be replaced.

It's discharging my car battery


Sounds like the capacitor is loading up the battery. Perhaps you could put a relay in to open-up the connection to the capacitor when the radio is off or when the car is off? Just put a large relay to break the (+) connection.

Hey i had 2 car amps +for 4 speakers(140W maxi) and a sub 12inch


1 cap, either .5, 1 or 1.5 farad will be fine. they make 5 10 and 20 farad that cost way more than u need to spend for 400 watts RMS. i like the rockford fosgates, you can get a low cost Tsunami, just make sure you follow the charging instructions.

Rockford amp cut out


Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.
