Power your in-car sound system with clean, high-fidelity dynamics using the Focal FPX 4.800. Part of the prestigious Focal Performance range, this ultra-compact Class D amplifier produces an impressive 4 × 120W RMS at 4 Ohms (or up to 2 × 370W RMS bridged), making it an ideal powerhouse for running premium front/rear component splits or a 2-way front stage paired with a dedicated subwoofer.

Engineered with an extruded aluminum heat-dissipating chassis, selectable 2/4-channel input modes, and independent active crossovers for each channel pair, the FPX 4.800 delivers audiophile acoustic control and stability even in compact vehicle installations.
