Focal FD 2.350

Overview

Our take on the Focal FD 2.350

If you want an audio upgrade but you're short on room, Focal's FD 2.350 may be the amp for you. This 2-channel amplifier packs a respectable punch, driving two speakers with up to 170 watts RMS each even though it's only the size of a small paperback book. You can also bridge the amp to mono mode to power a sub with 360 watts RMS.

When size matters

If you want an audio upgrade but you're short on room, Focal's FD 2.350 may be the amp for you. This 2-channel amplifier packs a respectable punch, driving two speakers with up to 170 watts RMS each even though it's only the size of a small paperback book. You can also bridge the amp to mono mode to power a sub with 360 watts RMS.

Without cover

No sacrifices

The amplifier's active high- and low-pass crossovers and bass boost let you get hands-on with with sound optimization. And if you're keeping your factory radio, the amp comes with external audio transformers that automatically detect and convert the high-level signals from your speaker wires.

Cool under pressure

The FD 2.350 uses Direct FET Technology to dissipate heat efficiently from its aluminum chassis, ensuring long-term reliability. And speaking of saving space, you can stack this amp with its FD Series 4-channel brother to power an entire system.

Very compact and sounds great. Got inside the front fairing of my Harley Davidson road glide without issue

Crutchfield Customer Review (What's this?)

I also needed a max power amp in a small package for my Harley Streetglide. Along with my Focal 6 1.2 speakers, I achieved a level of volume that was above the wind noise. If you've "upgraded" to an aftermarket system and are looking for an amp to do the job that can stack on top of the main unit & fit inder the fairing, I recommend this set up.

Pros: Compact & powerful!

Cons: Cost

Great Amp

Crutchfield Customer Review (What's this?)

Bought this amp for my Harley Street Glide. It fit perfect under the fairing right over the Alpine HU. This is a lot of power for the size. I still have some fine tuning to do on the gain and frequency but so far I'm very pleased. The volume is very loud. I would say this is the biggest most powerful amp you can fit under a batwing fairing. Also, the guys at tech support were great. I'd never done an install and they answered all my questions and made some great suggestions.

Pros: Size and Power

Cons: To early to tell if it has any.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples). Using CEA-2006 criteria, the Focal FD 2.350 is rated at 105 watts RMS x 2 channels.

2Ω Stable: The amplifier can also support a 2Ω load; the 2Ω power output is 170 watts RMS x 2 channels.

Bridgeable: The FD 2.350 is bridgeable to one channel at 360 watts RMS into 4Ω.

Stackable: All the FD series amps (FD 1.350, FD 2.350, and FD 4.350) have the same footprint, and can be stacked on top of one another.

Speaker Level Input: An external speaker level input transformer is included, used when your source unit doesn't have RCA outputs. The transformer is connected to the amp with the included wiring harness. The transformer's dimensions are approximately:

  • Width: 2-3/8"
  • Height: 1-1/4"
  • Depth: 2" (3" including wiring)

Auto Turn-on: When using a speaker level input, the amp will turn on automatically when it senses the input signal.

Controls

Gain: To accommodate the varying range of signal levels from today's factory and aftermarket radios, the FD 2.350 features an adjustable gain control; 0.2-5.0 volts line level (RCA) and 0.4-10.0 volts speaker level.

Crossover: Set the crossover switch to LPF (Low Pass Filter), Full (full range), or HPF (High Pass Filter).

Frequency: The crossover point is continuously variable from 40 Hz to 400 Hz.

Bass Boost: The bass boost, centered at 85 Hz, is variable from 0 dB (flat) to +12 dB.

Connections

Power Connections: The power, ground, and turn-on connections are 0.3" wide screw terminals. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Crimp-on spade connectors are included for all three terminals.

Speaker Outputs: There are 0.3" wide screw terminal outputs for two speakers. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Crimp-on spade connectors are included for both speakers.

Line Level Input: The line input is a pair of stereo RCA jacks.

Speaker Level Input: An external speaker level input transformer and wiring harnesses are included for the speaker level input.

Fuses: The amplifier uses two 15-amp mini blade-type fuses.
