4 x 30W + 2 x 70W amplifier, with an eight-channel signal processor, offering excellent sound quality and adjustability via easy-to-use software.
The amplifier operates in Class A/B, which produces an exceptionally warm and natural sound for your vehicle.
Plug & Play installation on over ten different Volvo models.

The ZDA6.8 DSP amplifier revolutionizes your car's audio performance in this price range, outperforming all factory-installed amplifiers.
Unlike most similar products that use Class D technology, the ZDAP-VOL1 utilizes Class A/B technology, producing a warmer and more natural sound that brings your music to life. Even without DSP adjustments, the sound quality is significantly improved, and the built-in DSP takes the sound even further, allowing you to fine-tune your car's sound system to your exact preferences - regardless of your musical taste.

Input Priority
Input Priority ensures seamless integration with your car's original head unit. You can use RCA input or digital sources such as optical S/PDIF input, coaxial input or built-in Bluetooth (Bluetooth 5.0) without losing important sounds from the original equipment, such as parking sensors, alarms and radio signals.
For example, if your vehicle's head unit has a high-pass filter that limits bass, you can bypass this limitation by streaming the audio directly to the amplifier via Bluetooth – while retaining all the functionality of the OEM system.

DSP outputs
The ZDA6.8 not only upgrades your system, but also allows you to expand it. Thanks to two freely configurable RCA DSP outputs (channels 7-8), you can connect, for example, a subwoofer amplifier and control it completely freely via DSP. Delay settings, crossover filters and equalizer options ensure top-class performance for additional components.

Software
You control the processor with free and easy-to-use PC software (compatible with Windows 10 and 11). Connect to your computer with the included USB-B cable and you have the following control options:
-
31-band parametric equalizer (PEQ) for all channels
-
Selectable filter types (Bessel, Butterworth, Linkwitz-Riley) and adjustable slopes from -6 dB to -48 dB
-
Time delay adjustments for all channels
-
Fully customizable channel routing
-
Custom Channel Links (Copy or Link)
These advanced features allow you to adjust your sound system perfectly to your own preferences.
