This power capacitor is an energy storage device. It is designed to supplement your car’s charging system when your audio amplifier places a high current demand upon it. This occurs, for example, when the music you are playing contains a loud, transient, deep bass signal. This product can discharge extremely rapidly on demand (e.g. from your amplifier’s short bursts) to deliver the current your car battery cannot produce. Thus, this enhances overall bass response of your car audio system. In addition, this product can filter out audio noise caused by the AC voltage which is induced in the amplifier’s power supply. A 1 Farad (1F) capacitor works up to about 500 watts of amplifier power. This product also features a digital voltage display.

Important safety precautions are mentioned in the user manual. Please read and understand all instructions before using the product. The capacitor must be charged before connecting the power cable to the positive terminal. Failure to charge the capacitor can be very dangerous. Please see the section titled “Charging the capacitor” on page 7 for instructions on how to charge the capacitor.

Mounting

Before you drill or cut any holes, investigate your car’s layout very carefully. Take special care when you work near the fuel tank, fuel lines, hydraulic lines and electrical wiring. Mount the capacitor in the location away from moisture, and where connection cables are not pinched or damaged by sharp objects.

Please refer to the user manual’s section titled “Installation precautions” on page 2 for mounting instructions. Before wiring, disconnect the negative terminal of the vehicle battery for safety. Make sure a fuse (not included) is installed in line with the positive battery terminal for short-circuit protection. Ensure that the ground wire is fastened on the ground point, and scrape away any paint, rust, or dirt from the ground point to provide a clean contact. Use wires of proper gauge for connection and consult an expert if in doubt about wire gauge selection. Securely connect all the cables and properly insulate bare wires.

1. Find a suitable location in the vehicle to mount the capacitor.
2. Secure the capacitor with four supplied screws as follows:
   • a. Use the four screw holes on the capacitor to mark the mounting holes on the mounting surface.
   • b. Drill the mounting holes on the mounting surface.
   • c. Place the capacitor in position, and attach the capacitor to the mounting surface using four screws.

Charging the Capacitor

The capacitor must be charged before connecting the power cable to the positive terminal. Failure to charge the capacitor can be very dangerous. To charge the capacitor, follow these steps:

1. Disconnect the power cable from the positive terminal of the capacitor.
2. Connect a resistor of at least 1 ohm, 10 watts between the positive terminal and the power cable.
3. Connect a voltmeter between the positive and negative terminals of the capacitor.
4. Connect the negative terminal of the capacitor to the vehicle’s metal frame.
5. Connect the power cable to the positive terminal of the capacitor.
6. Switch on the power supply and charge the capacitor until it reaches the desired voltage level.
7. Disconnect the resistor and voltmeter.

The capacitor is now charged and ready to use.

Important note about charging the capacitor
This capacitor must be charged before connecting the power cable to the POSITIVE (+) terminal on the capacitor. Failure to charge the capacitor will result in a large spark generated from the rapid inflow of current which can be very dangerous.

Electrical connection

CAP18

• For safety, disconnect the negative terminal of the vehicle battery prior to wiring.
• For short-circuit protection, make sure a fuse (not included) is installed in line with the positive battery terminal.
• Make sure the ground wire is fastened on the ground point. Scrape away any paint, rust or dirt from the ground point to provide a clean contact.
• Use wires of proper gauge for connection. Consult an expert if in doubt about wire gauge selection.
• Make sure wires are not squeezed or damaged by sharp edges. Securely connect all the cables and properly insulate bare wires.
• Reconnect the negative terminal of the vehicle battery only when all wire connections are correctly and securely made.

Make all wiring connections as shown in the illustration below, but do not connect the power cable from the positive battery terminal to the capacitor positive terminal.
Make the POSITIVE (+) terminal connection only after charging the capacitor .

Charging the capacitor

IMPORTANT!
You must charge the capacitor before connecting the power cable to the positive capacitor terminal. This can prevent a large spark generated from the rapid inflow of current, and eliminate the possibility of damaging the capacitor, battery and other audio devices.

1. Make all connections except for the POSITIVE (+) terminal connection to the capacitor. See the section “Electrical connection for CAP18” on page 5, or “Electrical connection for CAP8” on page 6. Make sure the NEGATIVE (-) and REMOTE terminal connections are properly and securely made.
2. Connect one end of the supplied resistor to the power cable from the positive battery terminal, and the other end to the POSITIVE (+) terminal on the capacitor.Caution! During charging, the resistor will become hot. This is normal. Exercise caution for the hot resistor.
   • The capacitor will start charging automatically. Charging generally takes 5 – 60 seconds.
   • During charging, the voltage shown in the 3-digit display will rise rapidly, then slowly as it approaches the voltage of your car battery. When fully charged, the displayed voltage will stop rising to show the voltage of your car battery.
   • To check with accuracy whether the capacitor is fully charged, measure the voltage of your car battery using a voltmeter. If fully charged, the displayed voltage will match the car battery voltage.
3. After charging is complete, remove the resistor from the power cable and immediately connect the power cable to the POSITIVE (+) terminal on the capacitor. The installation and charging process are now complete. You can begin using your audio system. Put the resistor in a safe storage location for future use when you need to discharge the capacitor.

Discharging the capacitor
Discharge the capacitor before you store the capacitor.
IMPORTANT! Never remove the capacitor without discharging the stored power. This can cause a dangerous electrical shock even after disconnection.

1. Disconnect the cables from the capacitor in the following order:
   • a. Positive cable (from the POSITIVE terminal)
   • b. Ground cable (from the NEGATIVE terminal)
   • c. Remote cable (from the REMOTE terminal)
2. Connect one end of the supplied resistor to the POSITIVE (+) terminal, and the other end to the NEGATIVE (-) terminal. After 1-5 minutes, the capacitor will be discharged (no sound can be heard from the buzzer). Caution! During discharging, the resistor will become hot. This is normal. Exercise caution for the hot resistor.
