The CO-650.1 D amplifier from Audio System offers different power ratings depending on the impedance. At 4 ohms, it delivers 1x 400 WRMS, which is sufficient for decent sound with a larger subwoofer. At 2 ohms, it reaches 1x 650 WRMS, which is ideal for powerful car systems that prefer intense bass. The high performance of the audio amplifier ensures that a stable and clear sound quality is maintained even at low impedances, with the efficiency of the CO-650.1 D particularly highlighted by the Class-D technology.
The CO-650.1 D amplifier from Audio System operates with Class-D amplifier technology, which ensures high efficiency. The efficiency of up to 84% means that the amplifier converts more electrical power into acoustic power while losing less energy as heat. This provides maximum sound output with minimal energy consumption, which is particularly advantageous for use in the car. Especially for operation in the trunk, this technology offers sustainable sound amplification, as less heat is generated, thereby supporting the longevity of the device.
The amplifier CO-650.1 D is equipped with several precise filter functions specifically designed for demanding audiophiles. The low pass filter allows for the selection of exactly the frequency ranges that are optimal for a subwoofer by filtering out higher frequencies. The subsonic filter is designed to eliminate unwanted low frequencies that are not audibly relevant, in order to maximize the amplifier's performance and protect the subwoofer. Both filters work together to ensure the clearest and most powerful bass reproduction possible, which can be specifically tailored to the user's preferences.
The continuously adjustable 0-180° phase shift of the CO-650.1 D allows for precise adjustment of the audio output phase. This feature is particularly useful when amplifiers and speakers are not installed at the same distance from the listener or when multiple subwoofers are used. By adjusting the phase, interference in the sound image can be minimized, resulting in clearer and more precise bass reproduction. The result is an optimally synchronized sound that significantly enhances the audio experience in the car and can be individually tailored to any acoustic environment.
The RTC bass remote control for the CO-650.1 D amplifier offers the convenience of adjusting the system's bass level directly from the driver's seat. This is particularly useful when listening to different music genres or when the bass level needs to be adjusted during live operation without manually touching the amplifier. This remote control allows for lightning-fast changes in bass intensity, ensuring optimal control and a tailored listening experience. Those with varying sound preferences especially benefit from the flexibility and user-friendliness of this feature.
The CO-650.1 D has compact dimensions of 230 x 47 x 171 mm, making it ideal for installation in the car, especially in the trunk or under a seat. Its space-saving design facilitates installation, as the amplifier can also be installed in vehicles with limited space. During installation, care should be taken to ensure adequate ventilation for heat dissipation to maintain the optimal performance and longevity of the device. The installation is flexible, as it is not restricted by oversized dimensions, making it easier to adapt to different vehicle models.
The RCA high-level input of the CO-650.1 D amplifier allows the device to be connected directly with speaker cables from the car radio, even if it does not have low-level outputs. This is particularly advantageous for cars without dedicated preamp outputs, as no additional adapters are needed to connect the amplifier. The automatic turn-on mechanism makes usage easier by activating the amplifier without manual switching as soon as a signal is detected. This functionality makes the CO-650.1 D versatile and compatible with a variety of in-vehicle audio systems.
The CO-650.1 D amplifier features an EQ that is specifically adjustable to 45Hz to enhance the bass range. If you want to adjust the bass level, you can do so within a range of 0 to 6 dB, depending on your personal preference for bass intensity. This function is useful if you prefer specific audio signatures that require more depth or to make a direct adjustment to the acoustic conditions of your vehicle. The right setting can significantly improve sound quality and be tailored to your individual listening habits.
When combining the CO-650.1 D with subwoofers, it is important to keep an eye on the impedance of the subwoofer in order to utilize its full performance. If the subwoofer is in the 4 or 2-ohm range, the amplifier provides the corresponding outputs of 400 WRMS or 650 WRMS. The impedance of the subwoofer must be compatible with the output impedance of the amplifier to avoid overload or damage. Additionally, the positioning of the subwoofer in the vehicle should be optimally chosen to ensure an even bass distribution in the vehicle interior.
The installation of the CO-650.1 D amplifier in the vehicle requires careful consideration of placement and wiring. It is compact enough to be mounted in the trunk or under the seat, while ensuring adequate ventilation. The connection is made via the RCA high-level input or classic preamp outputs, depending on your car radio. When wiring, high-quality cables and correct polarity should be used to minimize signal loss or interference. The continuously adjustable phase shift should then be adjusted according to the subwoofer position for optimal sound tuning.
