Focal FDP 4.600 Overview

Focal’s FDP 4.600 600-watt 4-channel car audio amplifier is a monster of an amplifier built into a compact chassis thanks to the digital amplifier design that was employed in its construction. It’s small enough to fit under a seat, but strong enough to power just about any set of speakers that exist.

Compact but Mighty

The Focal FDP 4.600 is capable of pushing out 200 watts per channel at 2 ohms from a chassis that is small enough to fit under the front seat of many vehicles. The Class D technology that was used in this amplifier is designed to help deliver maximum power efficiently so that heat buildup doesn’t become an issue.

Different Configurations

Most 4-channel amplifiers can boast about being able to be used in 4-channel, 3-channel, and 2-channel modes, but very few of them have the power output that the FDP 4.600 has. This amplifier is flexible in regard to it can be used to power speakers or subwoofers (or even both), so as you change your system’s layout, you just simply need to do some basic rewiring of the amplifier to adapt to your needs.

On-Board Controls

The on-board controls on the FDP 4.600 give you a lot of tunability over the attached speakers or subwoofers. The high-pass filters and low-pass filters will direct the appropriate audio frequencies to your speakers. As a bonus, the amplifier is also capable of bandpass mode which uses both the high-pass and low-pass filters at the same time (commonly, you can use only one or the other at a time). This is great feature to have if you’re looking to send a very specific frequency range to the connect speaker(s).

Control from the Driver’s Seat

Included with the Focal FDP 4.600 amplifier is a wired bass knob that can be ran to a convenient location up near the driver’s seat so you can quickly and easily adjust the amount of bass response by simply spinning the knob in the appropriate direction. Please note that this convenience is for a subwoofer that you have hooked up to the amplifier. It also has a LED clip light on it which will alert you if the output of the amplifier is clipping so you can make the necessary adjustments to stop it from occurring. Handy, huh?
