Frequent questions about CO-40.4 M

Welche Leistungsdaten bietet der CO-40.4 M Verstärker?

The CO-40.4 M from Audio System offers specific performance data suitable for demanding applications. It delivers an RMS power of 4x 40 watts at 4 ohms when operated in a standard configuration. With a load of 2 ohms, the power increases to 4x 60 watts RMS, making it very flexible for various systems. This variability in performance data allows you to operate different speaker configurations depending on the requirements of your audio system in the vehicle.

Wie funktioniert die automatische Einschaltung bei dem CO-40.4 M?

The CO-40.4 M amplifier offers a highly practical feature of automatic activation via the AUX input. This means that the amplifier automatically turns on as soon as a signal is detected through the AUX input, such as from a mobile phone or Bluetooth receiver. This priority for AUX ensures that the amplifier is only active when there is actually an audio signal present. Additionally, the input sensitivity is also adjustable, which simplifies integration into existing systems without the need to install additional control lines.

Welche Filter bietet der CO-40.4 M?

The CO-40.4 M from Audio System offers a range of filters that allow you to customize the sound. It is equipped with a switchable Low-Pass (LP) filter that can be set to either 80 Hz or 1500 Hz, which is ideal for tuning subwoofer frequencies. Additionally, there is a highly customizable High-Pass (HP) filter that can be adjusted continuously between 80 Hz and 4000 Hz to optimally process high frequencies. An additional Subsonic filter eliminates unwanted extremely low frequencies.

Wie flexibel ist der CO-40.4 M durch die Hochpegeleingänge?

The flexibility of the CO-40.4 M amplifier is supported by the high-level inputs. These inputs support an input sensitivity of 0.1 to 13 volts, allowing for a wide range of signal inputs. Thanks to the automatic power-on option via these high-level inputs, the amplifier can be operated without additional remote control connections. This technical feature is particularly valuable when you want to integrate the amplifier with existing audio systems that already deliver high levels.

Welche Abmessungen hat der CO-40.4 M und wie beeinflussen sie die Installation?

The CO-40.4 M from Audio System has compact dimensions of only 123 x 45 x 80 mm, making it particularly suitable for installations in tight spaces. These small dimensions allow you to accommodate the amplifier in a variety of vehicles without significantly interfering with the available space. The included 30 cm cable set with ISO also facilitates integration, as it simplifies the connection to existing wiring in the car and supports reduced space requirements.

Welche Anschlussmöglichkeiten bietet der CO-40.4 M Verstärker?

The CO-40.4 M amplifier from Audio System is equipped with multiple connection options to ensure comprehensive compatibility and ease of use. The switchable LP and HP filters allow for detailed sound control. The AUX input gives you the freedom to use various signal sources such as mobile phones or Bluetooth receivers. Together with the high input sensitivity of 0.1 to 13V, you can effectively integrate the amplifier into your existing audio system and connect different devices without any issues.

Wie beeinflussen die Kompatibilitätsmerkmale des CO-40.4 M die Nutzung in Fahrzeugen?

The CO-40.4 M from Audio System offers significant advantages in vehicle integration due to its technical features such as compact dimensions of 123 x 45 x 80 mm and automatic activation via AUX. These characteristics support seamless integration into various vehicle models without extensive modifications. Although no specific car brands are mentioned, the flexible input architecture and the included ISO cable set provide nearly universal compatibility, making it easier for you to use the amplifier in a wide range of systems and configurations.

Welche Rolle spielt der Subsonic Filter im CO-40.4 M?

The subsonic filter in the CO-40.4 M amplifier from Audio System is crucial, especially if you want to optimize the sound in your car. It acts as a kind of pre-filter that removes unnecessarily low frequencies from the audio signal that are inaudible to the human ear and would otherwise waste energy. This function is particularly useful for minimizing distortion in the subwoofer range and allowing the amplifier to operate more efficiently while ensuring the protection of the speakers from excessive excursions.

Welchen Nutzen bietet ein 30cm ISO-Kabelsatz beim CO-40.4 M Verstärker?

The included 30 cm ISO cable set with the CO-40.4 M amplifier from Audio System is specifically designed to significantly ease the installation process. ISO connectors are standardized connections that greatly simplify installation in vehicles, as they can be connected to many aftermarket radios and amplifiers without the need for special adapters. This feature saves you time and effort and allows for a seamless connection to existing wiring harnesses without the need to extensively address the individual vehicle wiring.

Welche Einsatzmöglichkeiten bietet die CO-SERIES speziell mit dem CO-40.4 M?

The CO-SERIES, specifically the CO-40.4 M, stands for versatility and adaptability. It offers all the features needed for high-quality sound experiences in vehicles. With the combination of automatic AUX activation, flexible filters, and adjustable input sensitivity, you can use the amplifier in a variety of configurations. The compact design allows for integration into almost any vehicle without requiring much space. Such characteristics make the CO-SERIES the ideal choice for audiophiles who value great flexibility and high sound quality.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
