Power-packed
Focal’s FPX 4.800 amplifier delivers 120 watts RMS per channel in 4-channel mode, or up to 370 watts RMS per channel when it’s bridged to 2-channel operation. This impressive power comes from a compact chassis that’s a little smaller than one of my Size 10 bedroom slippers, so it’ll probably fit just about anywhere in your vehicle. Focal’s engineers designed this amp to reproduce your music with unerring precision, so it’ll pair up nicely with high-performance components or subs.

Tone controls for a variety of applications
Separate high- and low-pass filters on the front and rear channels let you optimize the signal for the best tone without distortion. When powering a sub with the rear channels, the variable bass boost adds as much punch as needed.
