⚡ At a Glance
- • Energy Handling: 20 Farad capacity with ESR 0.0015 ohms for fast charge/discharge
- • Best for: Car audio enthusiasts upgrading amplifiers and bass systems
- • Not ideal for: Users who need integrated audio connectivity or system control features
A 20 Farad capacitor with very low equivalent series resistance, designed to supply quick bursts of current. Built-in voltage readout, LED music window and audible warnings help spot wiring faults and voltage issues.
More consistent bass, thanks to 20 Farad energy storage
Capacitance stores charge close to the amplifier, while the low ESR of 0.0015 ohms at 120Hz allows rapid discharge during transient peaks. Stored energy reduces the speed and depth of voltage sag under heavy loads.
Amplifier peaks receive immediate current support, keeping bass punch tight and helping to avoid momentary distortion during demanding tracks.
Clear system diagnostics, with a 3-digit voltage meter and audible warnings
The three-digit blue voltage meter shows readings to 0.1V increments for precise monitoring, while audible tones alert to reverse polarity and voltage faults. A blue LED window responds to music, giving visual feedback of system activity.
Fast visual and audible cues make it easier to spot wiring errors and voltage problems during installation and troubleshooting.
Easier servicing, with removable and clearly laid-out components
Component layout is designed for accessibility and use of standard parts, as noted in user feedback about removable sections and replaceable components. Clear internal arrangement supports straightforward inspection and repair.
Local repairs and troubleshooting are simpler, which helps extend service life and reduces time in the workshop.
