Its small footprint helps installers place it in tight spaces while delivering steady output and predictable behaviour in daily use.Power ratings are 420W RMS at 4 ohms, 720W RMS at 2 ohms and 1000W RMS at 1 ohm, providing flexible options from factory upgrades to dedicated bass installs. A 10Hz–250Hz response gives precise sub control, supporting deep notes and tight transients without masking the rest of the system.Total harmonic distortion is ≤0.2%, and the signal-to-noise ratio exceeds 90dB. These figures indicate a clean baseline that preserves low-frequency detail and impact. Input sensitivity is adjustable from 0.2V to 6V, so level matching is straightforward with factory head units or aftermarket decks.The recommended protection is 2 × 45A fusing. Dimensions are 233 × 184 × 55mm, which aids discreet placement under seats, in side panels or near an enclosure. Power and speaker terminals are positioned for tidy cable runs that support a reliable connection.Setup is simple: match the load to the rated outputs, set gain within the published sensitivity range, and align the crossover to the subwoofer and enclosure. Used this way, the X11000.1 provides firm low-end control with the headroom needed for dynamic tracks and varied styles.What’s in the box: 1× Excalibur X11000.1 amplifier, connection terminals, mounting hardware, user manual.By combining flexible power at common impedances with a practical chassis size, the Excalibur X11000.1 offers a clear path to stronger bass performance.
