Feature: 1. The condenser installation is under the case of subwoofer amplifier, to compensate for the lack of power supply of the bass amplifier. Improves poor performance due to insufficient power amplifier. 2. Audio capacitors provide instant power on demand to feed your power amps and stabilize this voltage to keep your system running at peak performance. 3. The integrated digital display informs you of system status and performance, clear and intuitive. 4. The installation is simple and does not require complicated operations. 5. Precision manufacturing makes it has stable performance and long service life. Specification: Condition: 100% Brand New Item Type: Car Audio Capacitor Material: Aluminum Alloy Color: As picture shown Installation Instructions: 1.To achieve the best effect, car audio power condenser, the installation location should be as close as possible to the power amplifier, use a shorter power connection line, at the same time as the car audio of Power capacitor In a place not easy to touch, to some extent it isolated the heat generated by the power amplifier 2. The power line should be as short as possible, the fuse is not installed between the capacitance and the power amplifier. But make sure the main battery cable uses the proper fuse to protect the circuit from the power supply. 3. De car audio power capacitor The anode line should be as short as possible and connect directly to the bare wire of the metal surface of the car. 4. The power cable capacitor must be the same GA number as the power cable of the power amplifier. 5. Connect one end of the control line to the car auto audio antenna connector.. Package List: 1 x Car Audio Capacitor1 x Mounting Screw Pack Note: New and old models of this protect will be shipped randomly.
