Specification: Condition: 100% Brand NewItem Type: 4 Farad Power CapacitorMaterial: Aluminium AlloyColor: As the Picture ShownDescription: Todays car audio amplifiers need huge amounts of current. Often a vehicles electrical system is unable to provide it. With your cars air conditioning running, the factory electrical charging system may already be operating at only 70% of full capacity. When a bass note hits or when playing your system very loudly, there may not be enough electrical energy to power your amplification system properly causing your music to sound strained and distorted. Capacitors are designed to store enough electrical current and to release this energy extremely fast due to their superior design and low internal resistance. In addition, as quick as your amplifier needs a new current surge, your capacitor will provide it. This continuous cycle of power discharge and recharge guarantees flawless bass playback. . Package List: 1 x 4 Farad Power Capacitor 1 x Bag of Screw Note: Only one wrench is included in the accessories bag.
