Everything you need to know about the product
The Focal FPX 1.1000 is a compact yet ultra-powerful mono Class D amplifier engineered to deliver deep, clean, and controlled bass. Pumping out 420W RMS at 4 Ohms — and stable down to 2 Ohms and 1 Ohm — this amp is designed to meet the needs of serious bass enthusiasts and audiophiles alike.
Ideal for powering premium subwoofers or audiophile-grade bass systems, the FPX 1.1000 features a full suite of advanced tuning options including an active low-pass crossover, subsonic filter, bass boost, and phase adjustment. It also includes output lines for expanding your system and a remote level control for on-the-fly adjustments from the dashboard.
Despite its powerful performance, the FPX 1.1000 maintains a compact form factor (29.7 x 13.2 x 5.3 cm), allowing easy installation even in tight or concealed spaces.
Specifically developed for powering all types of subwoofer, the FPX 1.1000 is stable at 4 Ohms, 2 Ohms, and 1 Ohm, delivering a respective power of 420, 700, and 1000 Watts RMS. Whether it's an audiophile bass system or a high-output subwoofer build, the FPX 1.1000 handles it all.
The amplifier features all the settings you'd expect from a high-end bass amplification system: an adjustable low-pass active crossover with a 24 dB/octave slope, a subsonic filter with a 24 dB/octave slope, bass boost, and phase control.

For a powerful, musical amplifier, heat dissipation is essential. That's why FPX amplifiers are built on thick aluminium frames with optimal cooling capacity. The distribution of components has been carefully researched to maximise the chassis's thermal performance.
The FPX 1.1000 comes supplied with a remote control for bass level adjustment from the driver's seat, and a pair of line outputs for distributing the audio signal to a second amplifier. This makes it especially useful for setting up a dedicated bass channel with two subwoofers and two amplifiers.

Delivers 420W RMS at 4 Ohms, 700W RMS at 2 Ohms, and 1000W RMS at 1 Ohm for serious subwoofer performance.

High-efficiency Class D design keeps the unit compact and cool while maintaining clean, musical bass output.

Active low-pass crossover and subsonic filter, both with steep 24 dB/octave slopes, precisely control the frequency range delivered to the subwoofer.

Onboard bass boost and phase adjustment allow fine-tuning of low-frequency output to suit any subwoofer and vehicle combination.

Supplied remote controller allows the driver to adjust bass level from the dashboard without reaching to the amp.

Pair of output lines lets you connect a second amplifier — ideal for dual-subwoofer bass channel setups.

Thick aluminium frame with optimised component layout provides efficient heat dissipation at sustained high output levels.
