SounDigital 400.4 EVO6 Review
Hear More From Your Music
Want your favourite music to sound clearer and more engaging inside your car? The SounDigital 400.4 EVO6 adds dedicated amplification, helping your speakers perform beyond the limits of many built-in head-unit amplifiers. It delivers 66 watts RMS per channel at 4 Ohms or 100 watts RMS per channel at 2 Ohms. With suitable speakers and correct tuning, you can enjoy clearer vocals, more defined instruments, and greater impact as you turn up the volume. Whether you are enjoying Kenyan hits on your commute or favourite tracks on a long drive, your music becomes the focus.
Bring Your System Together
More power alone won’t guarantee better sound quality; your components need to work together. The SounDigital 400.4 EVO6 features 80 Hz high-pass and low-pass filters, each with a 12 dB-per-octave slope. When configured appropriately, high-pass filtering reduces deep-bass demands on compatible door speakers. This lets them concentrate on the frequencies they reproduce more effectively, supporting a more balanced listening experience. Its 8 Hz-20 kHz frequency response and 94 dB signal-to-noise ratio support full-range playback with a clean signal when your system is properly installed and tuned.
Power Without the Bulk
You can upgrade your car’s sound system without sacrificing valuable installation space. Measuring approximately 3.4 x 4.2 x 1.8 inches, the SounDigital 400.4 EVO6 fits compact installation plans. Run its four channels to compatible speakers, or bridge them to deliver 2 x 200 watts RMS at 4 Ohms. Its 0.2-2V RCA input sensitivity helps your installer match the amplifier to your receiver’s pre-out signal. With proper wiring, protection, and tuning, you can enjoy a more dynamic listening experience that suits your vehicle and your music.
