Focal FDS 2.350<\/strong> is a 2-channel car audio power amplifier<\/strong> designed to power speakers in an in-car audio system. Its two channels can drive a stereo speaker pair or be bridged to power a single 4-ohm load. When choosing compatible speakers, the main considerations are the load impedance and the conditions under which the amplifier\u2019s power figures were measured.<\/p>\n

Understanding the power ratings<\/h2>\n

At 4 ohms, the specified output is 2 \u00d7 105 W RMS CEA power<\/strong>. At 2 ohms, the amplifier is rated at 2 \u00d7 170 W maximum power<\/strong>. With the channels bridged into a 4-ohm load, it delivers 1 \u00d7 360 W maximum power<\/strong>.<\/p>\n

These figures should not be treated as directly equivalent. RMS and maximum power describe different measurement conditions, while changing the load impedance also changes how the amplifier operates. When selecting speakers, first consider their nominal impedance and continuous power rating. The maximum-power figure should not be used as the sole matching criterion.<\/p>\n

Channel configuration and connection<\/h2>\n

The separate channels carry the left and right signals, making the amplifier suitable for a stereo speaker pair. This arrangement preserves channel separation and allows each speaker to be powered independently.<\/p>\n

In bridged mode<\/strong>, both channels work together to drive one load. Choose this configuration when the system requires one more powerful channel and the connected load is 4 ohms. The 2 \u00d7 170 W rating at 2 ohms applies only to two-channel operation and must not be used as a bridged-mode rating. Follow the terminal polarity markings on the amplifier when making the connections.<\/p>\n

Signal characteristics<\/h2>\n

The specified frequency response<\/strong> uses -3 dB limits. These indicate the measurement points at which the signal level has already fallen below the reference level. This figure does not describe the reproduction range of the speakers connected to the amplifier.<\/p>\n

The stated total harmonic distortion of 0.07%<\/strong> describes the proportion of distortion present during measurement. Channel separation is measured at 1 kHz and exceeds 65 dB. This value helps indicate the electrical separation between the left and right channels.<\/p>\n

The signal-to-noise ratio<\/strong> exceeds 84 dBA under the stated 1W\/A condition. It should only be compared with ratings obtained under the same measurement conditions.<\/p>\n

Installation position and system setup<\/h2>\n

Mount the amplifier securely in a stable location inside the vehicle, leaving enough space for air to circulate around its casing. Do not cover it with trim materials or install it next to direct heat sources. The chosen position must also allow the unit to be fastened safely.<\/p>\n

It is advisable to route the power and signal cables separately inside the vehicle. This reduces the likelihood of noise from the alternator or other electrical circuits entering the audio signal. The ground connection should be short and securely attached to a suitable point on the vehicle body.<\/p>\n

Begin system adjustment with a lower signal level. Increase the volume gradually and listen for audible distortion. Base the final setting on the nominal power rating of the connected speakers rather than on a maximum-power figure.<\/p>\n

FAQ<\/h2>\n

When should I use the two-channel configuration?<\/h3>\n

Use it when you want to power the left and right speakers of a stereo system separately. Each channel carries its own audio signal.<\/p>\n

When is bridged mode useful?<\/h3>\n

It is suitable for a single 4-ohm load when one more powerful channel is required. In this mode, the amplifier no longer operates as a stereo pair.<\/p>\n

Can all three power ratings be compared directly?<\/h3>\n

No. They are stated using different impedances, channel configurations, and types of power rating. Only compare figures measured under equivalent conditions.<\/p>\n

How can I reduce the risk of unwanted noise?<\/h3>\n

Route signal cables separately from power wiring. Also use a short, secure ground connection attached to a suitable point on the vehicle body.<\/p>\n

What does the -3 dB frequency-response rating mean?<\/h3>\n

At the limits of the stated range, the output level is 3 dB below the reference level. This is a measurement condition, not a characteristic of the connected speakers.<\/p>\n","protected":false},"excerpt":{"rendered":"
