Channel Configuration Flexibility

One of the standout features of the X302-4 is its adaptability in channel configuration. It can be used in various setups:

• 4-Channel Mode: In this configuration, each channel provides 50 watts RMS. You can use these channels to power a pair of speakers, delivering a balanced and clear soundstage in your car.

• 3-Channel Mode: This mode is a hybrid approach, where you use the front channels to power a pair of speakers and bridge the rear channels to deliver a powerful 150 watts RMS to a subwoofer. It's a perfect balance between clear vocals and robust bass.

The flexibility to switch between these configurations ensures that your audio system can evolve as your preferences change, making the X302-4 a valuable long-term investment.

Fine-Tuning Your Audio

The X302-4 goes beyond just power; it also offers fine-tuning options to optimize your sound:

• High and Low-Pass Filters: These filters enable you to fine-tune the audio output according to your car's acoustics and your speaker preferences. This customization ensures that you get the most out of your audio system.
• Bass Boost (B Channels): The amplifier provides a bass boost option specifically for the B channels. You can adjust this boost to achieve the ideal bass tone that complements your music taste. It's like having a custom EQ for your bass frequencies.

Convenient Class D Technology

Class D technology is at the heart of the X302-4's design. This technology ensures that the amplifier runs cool, even during demanding audio sessions. It also enhances the amplifier's overall reliability, ensuring consistent performance. Moreover, Class D technology is known for its efficiency, generating less heat compared to Class AB amplifiers. This efficiency not only enhances performance but also contributes to the amplifier's compact design, allowing it to fit into tight spaces within your car.

Separated Circuit Boards for Enhanced Sound Quality

To maintain pristine audio quality, Kenwood implemented a unique approach. The X302-4's internal circuitry is divided into three separate, non-overlapping circuit boards, each handling analog, digital, and power supply functions. This design minimizes interference between these circuits, resulting in improved sound quality that will delight your ears.

Seamless Integration with Your Audio System

The X302-4 is engineered to integrate seamlessly with various audio systems, making it compatible with almost any mobile audio setup. It offers multiple input options, ensuring that you can connect it to your car's aftermarket receiver effortlessly. Here are some features that contribute to this seamless integration:

Multiple Input Options

The X302-4 accepts input signals via RCA cables from your aftermarket receiver. Additionally, it can receive signals via your vehicle's speaker wiring. This versatility ensures compatibility with a wide range of mobile audio systems.

Signal Sensing for Auto Activation

The amplifier features a signal-sensing turn-on circuit on the speaker-level inputs. When it detects a signal (up to 50 watts), the amplifier will automatically power on. Once the signal is no longer detected, the amp will turn off. This feature simplifies installation and eliminates the need for a separate remote turn-on lead to the receiver or fuse box.

In-Depth Control and Adjustability

The Kenwood eXcelon X302-4 comes equipped with independent controls for the A and B channels. This level of control empowers you to fine-tune your audio system to perfection. Here are the key controls:

• Input Sensitivity: The Input Sensitivity controls allow you to match the amplifier's input to the preamp output level of your source unit. You can make precise adjustments between 200mV (0.2V) and 5V, with clear markings for reference.
• Selectable Crossovers: The amplifier's crossovers can be configured as high-pass, low-pass, or full range. Each crossover's slope is 12dB per octave, and the crossover point is continuously variable from 50Hz to 200Hz. This feature gives you control over the frequency distribution for your speakers and subs.
• Bass Boost (B Channels Only): The X302-4 provides a dedicated bass boost for the B channels. You can adjust the boost level between 0dB and 18dB, centered at 40Hz. This allows you to dial in the perfect amount of bass to suit your musical preferences.

Connections Made Easy

The X302-4 is designed for straightforward connections, with features that simplify the installation process:

• Line In: The amplifier features two pairs of line-level RCA inputs labeled as A and B. These inputs accommodate signals ranging from 200mV to 5V, ensuring compatibility with a variety of source units.
• Power/Ground/Remote Turn-On: The power, ground, and remote turn-on connections feature screw terminals that can accommodate spade connectors. These connections are designed to be secure and reliable.
• Speaker Output: The amplifier provides four pairs of screw terminals for connecting your speakers. The terminals are 0.34" wide, allowing the use of spade connectors. The X302-4 is optimized for 4" loads but can also handle 2" loads if needed.
• Speaker Level Input: In cases where you don't have an RCA line-level signal available, the amplifier includes an 8" speaker-level input harness. This option makes installation more versatile, ensuring that you can connect to your source unit effectively.
• Fuses: Two 20-amp ATC fuses are installed in the amplifier to protect it. It's important to note that a 40-amp fuse rating is recommended, and it should be installed within 18" of the battery. This ensures that your amplifier receives adequate power while maintaining safety.
