Caratec Audio CAS207D sound system for Fiat Ducato/Citroen Jumper and Peugeot Boxer from 2007 with optional Caratec speakers CAK1650.DU black

Caratec Audio CAS207D sound system for Fiat Ducato, Citroen Jumper and Peugeot Boxer from 2007. The active Caratec Plug & Play sound system CAS207D and significantly optimizes the sound of the speakers. It consists of a compact 4-channel amplifier with integrated DSP, a subwoofer and a plug & play wiring harness.

The active Caratec Plug & Play sound system consists of a compact amplifier (4-channel) with integrated DSP (Digital Signal Processor) and a subwoofer. The amplifier further optimizes the sound of the retrofitted Caratec CAK1650.DU speakers and drives the powerful subwoofer. This creates a completely new and convincing sound experience in the blink of an eye. The sound detaches itself from the speakers and floats above the dashboard. The subwoofer and the relief of the originally installed speakers from low frequencies create a much clearer, lively sound image. Speech intelligibility is also significantly improved. This results in music enjoyment even at low volumes.
Suitable for all radios except the original Fiat radio. Suitable for vehicles with retrofitted Caratec speakers CAK1650.DU in the front doors. Possibly existing speakers in the living area will continue to be controlled by the radio.

The plug-and-play wiring harness for the radio's ISO connectors enables connection and installation in a very short time; separate connections to the vehicle are not required. The subwoofer is usually mounted under the passenger seat or the driver's seat. If there is no space there, it is also possible to mount it in another place (e.g. behind the driver's seat instead of the cover). If required, a 2m extension cable CAZ100L is optionally available.

Caratec's sound systems use digital amplifiers to drive the vehicle's speakers and also offer a dedicated subwoofer. On the one hand the series loudspeakers are relieved, because they must play only in their traditional frequency ranges and are released from the bass playback - that alone gives already once clearly more sound quality. On the other hand, the control is carried out with considerably more power. In the case of the sound system for the Ducato with four series loudspeakers, this means two 20-watt sine wave outputs and an additional two 40-watt outputs for the subwoofer channels. The total output is 120 watts (sine wave) or 240 watts (music). This is made possible by a high-tech amplifier with a circuit board that is just half the size of a postcard.

It contains a converter that converts the analog signals from the four speaker outputs of the series radio into digital material. This is processed by a digital sound processor (DSP) with 56-bit resolution and 50 MIPS computing power located on the same circuit board, which optimizes the frequency responses to suit the respective vehicle interior. Low-noise 24-bit digital-to-analog converters are used to convert the signals back into analog signals for driving the loudspeakers. The amplifier is not affected by under- or overvoltage, is insensitive to short circuits to ground or positive and has an overtemperature protection. The subwoofer placed under the passenger seat has a bass reflex construction with high-pass filter, measures 8 liters net volume and has a power handling of 100 watts sine. The impedance of the 165-millimeter woofer is two times two ohms. Its hand-scooped cellulose cone is particularly torsion-resistant, is reliably guided by a long-term stable rubber surround even at large excursions, and is protected by a steel cover.

The drive is taken over by a double voice coil in conjunction with a particularly generously dimensioned ferrite magnet, which results in optimal Thiele/Small parameters. The high-pass filter provides a lower lower cut-off frequency and higher maximum sound pressure level with reduced distortion. This effort results in a great sound experience, as revealed by extensive listening sessions.
