Stinger SPC505 5 Farad PRO Digital Hybrid Capacitor

Stinger SPC505 5 Farad Pro Digital Hybrid Capacitor for Car Audio Systems up to 1000 Watts

The SPC505 from Stinger is a 5 farad pro hybrid capacitor designed for car audio systems up to 1000 watts. It stabilises battery voltage during high-demand bass transients, reduces headlight dimming, and monitors system voltage, functioning similarly to a battery and capacitor combination in a single industrial-styled unit.

Product overview

High-powered car audio amplifiers draw significant current during bass transients, which can cause voltage sag in the vehicle's electrical system. This voltage drop manifests as headlight dimming, reduced amplifier performance, and audible degradation in bass response. The SPC505 addresses this by storing and releasing charge rapidly during these high-demand peaks, stabilising voltage across the system and allowing the amplifier to perform at full output without pulling down the vehicle electrical supply.

The pro hybrid capacitor design functions similarly to a combined battery and capacitor, providing both charge storage capacity and rapid discharge capability suited to systems up to 1000 watts. The built-in digital display monitors system voltage, providing a real-time view of the vehicle's electrical supply. The industrial styling makes it suited to visible installations in custom and show builds.

Features and benefits

5 farad capacitance rating: The 5 farad rating provides sufficient charge storage capacity for car audio systems up to 1000 watts, delivering rapid current supply during bass transients without relying solely on the vehicle battery.

Pro hybrid capacitor design: The hybrid design functions similarly to a battery and capacitor combination, providing both charge storage and rapid discharge capability in a single unit suited to high-demand car audio applications.

Stabilises battery voltage: Stores and releases charge during high-demand peaks to stabilise vehicle battery voltage, maintaining consistent amplifier performance and preventing voltage sag during heavy bass passages.

Minimises headlight dimming: By supplying stored charge during current peaks, the SPC505 reduces the voltage drop that causes headlights to dim in time with bass hits, a common issue in high-powered car audio systems.

System voltage monitoring: The built-in digital display monitors and shows real-time system voltage, providing a useful reference for the vehicle's electrical supply condition during operation.

Industrial styling: The unique industrial design makes the SPC505 suited to visible installations in custom enclosures and show builds where the capacitor is part of the display.

Frequently asked questions

What does a capacitor do in a car audio system?
A capacitor stores electrical charge and releases it rapidly during high-demand bass transients, supplementing the vehicle battery and preventing voltage sag. This stabilises system voltage, maintains amplifier performance at peak output, and reduces headlight dimming caused by heavy current draw.

What system power rating is the SPC505 suited to?
The SPC505 is rated for car audio systems up to 1000 watts. For systems above this power level, a higher-rated capacitor or additional battery upgrade may be required. Contact us if you need guidance on the correct electrical upgrade for your system.

What is a pro hybrid capacitor?
A pro hybrid capacitor combines the charge storage characteristics of a traditional capacitor with additional energy storage capacity more similar to a battery, providing both rapid charge delivery during transients and a larger overall energy reserve compared to a standard capacitor of the same farad rating.

Does the SPC505 replace the need for a second battery?
The SPC505 supplements the vehicle battery during high-demand transients but does not replace the sustained energy storage that a second battery provides. For very high-powered systems or extended listening away from the alternator, a dedicated secondary battery is still the recommended solution. Contact us for guidance on the right electrical upgrade for your specific system.

How is the SPC505 wired into the car audio system?
Capacitors are typically wired in parallel with the amplifier, as close to the amplifier as possible, using the same gauge power and ground cable as the amplifier installation. Contact us for guidance on correct capacitor wiring for your specific system configuration.
