Focal AP-4340 | 4-Channel Class AB Power Amplifier

Focal AP-4340 is a professional-grade solution for drivers looking to amplify their entire soundstage with clarity and warmth. Operating in Class AB, this amplifier prioritizes sound quality over raw efficiency, delivering a smoother and more natural audio reproduction than standard Class D amps. With its bridgeable design, it offers the flexibility to power four speakers or a combination of front speakers and a subwoofer, making it the perfect "Blockbuster" foundation for a premium car audio setup.

Key Features and Benefits:

• Authentic Class AB Topology: Known for superior musicality, the Class AB design minimizes distortion and provides a warmer sound profile, which is ideal for high-end component speakers like the Focal Access or Slatefiber series.

• Versatile Power Output: Delivers 4x70W RMS (at 4 Ohms), providing plenty of headroom for clear vocals and punchy mid-bass. It can also reach 4x95W RMS at 2 Ohms for high-output configurations.

• High-Power Bridgeable Mode: Easily switch to a 3-channel setup by bridging two channels to deliver 190W RMS x 2 (at 4 Ohms). This provides enough dedicated power to drive a high-performance 8-inch or 10-inch subwoofer.

• Integrated High-Pass & Low-Pass Filters: Features adjustable crossovers (50Hz to 250Hz), allowing you to filter out deep bass from your door speakers and direct it only to your subwoofer for a cleaner, more balanced sound.

• Aviation-Grade Aluminum Heat Sink: The heavy-duty chassis acts as a high-efficiency heat exchanger, ensuring the amplifier remains cool and stable even during long periods of high-volume playback.

• Flexible Input Options: Equipped with RCA inputs for aftermarket head units, ensuring a clean signal transfer for the best possible audio resolution.

• Compact Footprint: Despite its high-power output, the streamlined design allows for easy installation under seats or in the trunk, making it a favorite for car professionals seeking a "top model" stealth install.
