A car audio accessory built to supply reserve power for heavy bass hits and sudden amplifier demands, Pyle 5.0 Digital Power Capacitor helps prevent voltage sag. Blue digital readout provides visible voltage feedback and added stability so loud tracks remain clean. Is it the practical upgrade most car-audio enthusiasts need?

⚡ At a Glance
  • Power Stability: Supports transient bass demands by supplying stored energy during amplifier peaks
  • Best for: Car-audio enthusiasts and installers running high-demand aftermarket systems
  • Not ideal for: Owners of factory-standard, low-power systems that rarely experience voltage sag

A 5.0 farad digital display capacitor with blue voltage readout, brushed aluminium case and chrome-plated post kits. Includes over-voltage and polarity protection and mounting hardware, suitable for DC 12–24V systems.


Reliable Bass Response – Thanks to 5.0 farad capacitance

5.0 farad capacitance stores electrical charge and releases it during amplifier peaks, smoothing rapid current demands and preventing short-term voltage drops.

Stored reserve energy reduces voltage sag during heavy bass, keeping output tight and avoiding dimming lights or audible distortion.

Simple Voltage Monitoring – With Blue Digital Display

Blue LED voltage readout delivers a live measurement of available system voltage so electrical status can be checked at a glance.

Quick visual feedback makes gain-setting and basic troubleshooting faster, removing the need for a separate voltmeter during setup.

Protected Installation – With Polarity and Over-Voltage Circuits

Electronic polarity protection guards against incorrect wiring while over-voltage protection helps absorb supply spikes; components rated for operation up to 105°C.

Safer wiring and added protection reduce the risk of component failure during installation and under heavy load, improving long-term reliability.

✨ The 4 Key Reasons for Pyle 5.0 Digital Power Capacitor
  1. Blue Digital Voltage Readout – Allows quick system voltage checks without additional tools
  2. Over-Voltage and Polarity Protection – Reduces risk of damage from wiring mistakes and spikes
  3. Brushed Aluminium Case & Chrome Posts – Durable mounting with a neat, OEM-style finish and professional look
  4. Includes Mounting Hardware – Simplifies installation for DIYers and professional installers alike
