Description

The BOSS AUDIO CAP18 18 Farad Capacitor is an essential component for car audio systems requiring stable, consistent power delivery to amplifiers. This passive electrical component stores energy and releases it rapidly to support dynamic musical content, from soft vocals to heavy bass notes, preventing voltage drops during peak demand. The CAP18 features an audible warning tone system that alerts you to reverse polarity, over-voltage conditions, and low battery voltage, protecting your equipment from damage. A bright blue LED voltage meter with digital readout displays the unit's working voltage to the decimal point with accuracy of plus or minus 0.1 VDC, allowing real-time monitoring of system performance. The capacitor automatically enters sleep mode when volume is low or no voltage variation is detected, optimising efficiency. By maintaining steady power to your amplifiers, the CAP18 delivers a cleaner, better-sounding audio system whilst ensuring reliable operation during demanding playback.

Key Features

The BOSS AUDIO CAP18 stores electrical energy and releases it quickly to amplifiers, stabilising power during dynamic music playback with varying soft and loud passages.

Audible warning tones alert you to reverse polarity connections, over-voltage limits, and low battery voltage conditions detected by the capacitor's monitoring system.

A bright blue LED voltage meter displays the capacitor's working voltage digitally to the decimal place, accurate within plus or minus 0.1 VDC for precise power tracking.

Automatic sleep mode activates when volume is low or no voltage variation is present, reducing power consumption and extending operational efficiency.

The 18 Farad CAP18 capacitor provides power reserve support specifically designed for car audio amplifiers requiring constant, stabilised voltage for optimal performance.
