The Focal FDS 4.350 car amplifier<\/strong> is a four-channel audio power amplifier designed for in-car sound systems. It can power four speakers through separate channels. Alternatively, its two channel pairs can be used in bridged mode<\/strong>.<\/p>\n

With a 4-ohm load, the specified output is 4 \u00d7 58 W RMS CEA<\/strong>. This is the most important figure when comparing the continuous output of this model with a speaker’s RMS power rating. The maximum power figures at 2 ohms and in bridged mode are not RMS ratings.<\/p>\n

Power and channel configuration<\/h2>\n

Four channels allow the front and rear sections of a car audio system to be amplified by a single unit. Each channel delivers 58 W RMS CEA into 4 ohms. This arrangement is suitable when planning a four-channel system without adding a separate second power amplifier.<\/p>\n

At 2 ohms, the specified figure is 4 \u00d7 100 W maximum power<\/strong>. It should not be compared directly with the 4-ohm RMS rating. When selecting speakers, consider their impedance and RMS power separately, along with the intended channel configuration.<\/p>\n

In bridged mode, the two channel pairs can operate as two higher-powered channels. The specified output in this configuration is 2 \u00d7 200 W maximum power into 4 ohms<\/strong>. The bridged load impedance must be 4 ohms. This mode should not be planned for a 2-ohm load.<\/p>\n

Understanding the audio specifications<\/h2>\n

The frequency response<\/strong> extends from 10 Hz to 50 kHz at the -3 dB limits. This measurement tolerance matters when comparing the amplifier with other models. It identifies the boundaries at which the signal level has fallen by three decibels.<\/p>\n

Total harmonic distortion<\/strong> is rated at 0.05%. This figure describes the proportion of harmonics that the amplifier adds to the signal. The source, power supply, speakers, and the way the system is matched also affect the final result.<\/p>\n

Channel separation<\/strong> is greater than 65 dB when measured at 1 kHz. This specification describes the degree of signal overlap between channels. The signal-to-noise ratio<\/strong> is stated as greater than 84 dBA with a 1 W\/A measurement notation.<\/p>\n

Installation and system adjustment<\/h2>\n

Before installation, choose either the four-channel arrangement or the bridged two-channel configuration. This decision determines the required speaker impedance, cable routing, and the correct power figure to use for comparison. In bridged mode, connect each channel pair according to the amplifier’s polarity markings.<\/p>\n

Install the amplifier on a firm surface in a dry, ventilated part of the vehicle. Leave open space around the casing for airflow. Do not cover the unit with carpet or other materials that retain heat.<\/p>\n

Select the thickness of the power and speaker cables according to their length and the system’s current requirements. It is advisable to route signal cables separately from the power cable. This layout reduces the chance of noise from the vehicle’s electrical system entering the audio signal.<\/p>\n

When switching on the system for the first time, begin with a low source volume. Set tone correction controls to neutral, then adjust the system levels gradually. Stop increasing the level if you hear harshness or compressed dynamics. The maximum power figure is not a suitable reference for setting everyday listening volume.<\/p>\n

FAQ<\/h2>\n

When should I choose a four-channel configuration, and when should I use bridged mode?<\/h3>\n

Choose the four-channel configuration when you want to power four speakers through separate channels. Choose the bridged configuration when you want to combine the channels into two bridged pairs and power two 4-ohm loads.<\/p>\n

How should I compare its output with a speaker’s power rating?<\/h3>\n

Use the 4 \u00d7 58 W RMS CEA rating at 4 ohms for comparison. The speakers’ RMS power and impedance must suit the selected system configuration.<\/p>\n

Can I connect a 2-ohm load in bridged mode?<\/h3>\n

The stated bridged power applies to a 4-ohm load. A bridged installation must therefore be planned for a 4-ohm load, not a 2-ohm load.<\/p>\n

Can I connect a subwoofer?<\/h3>\n

A bridged channel pair can be used with a 4-ohm load. The subwoofer’s RMS power must be matched separately because the 200 W figure is a maximum power rating.<\/p>\n

Where should the amplifier be installed in the vehicle?<\/h3>\n

Choose a firm, dry, and ventilated location. Leave room for air circulation, and protect the cables from being pinched or contacting sharp edges.<\/p>\n

How should I begin adjusting the system?<\/h3>\n

Start at a low volume with tone correction controls set to neutral. Increase the levels gradually while checking that the sound remains clean through every channel.<\/p>\n","protected":false},"excerpt":{"rendered":"
