Amplifier with DSP Processor Musway M6v4 EVO
Musway M6v4 EVO is a 6-channel amplifier with an integrated DSP processor that ranks among the most successful and highly awarded models in its category. It is the direct successor to the legendary M6, which defined the segment of compact DSP amplifiers, and in its current generation it delivers a significant step forward in power, sound and features. The amplifier received the prestigious EISA Best Product award in the In-Car Upgrade category for the 2025–2026 season and many other accolades on the German scene. The M6v4 combines six powerful amplifier channels with an advanced 8-channel DSP, enabling fully active systems without the need for an external processor. The EVO version is supplied with a harness with open leads for custom installation. Seamless integration into modern vehicles including start-stop systems, high-level inputs with EPS® and IFT technology for interference minimization are standard.
Power that exceeds expectations
The M6v4 delivers a significant power increase over the previous generation while retaining compact dimensions. The six amplifier channels provide ample power for complete vehicle sound systems, including active speaker management. The amplifier delivers 6 × 80 W RMS at 4 Ω and 6 × 130 W RMS at 2 Ω, with real-world measurements often reaching even higher values. Bridgeable configurations allow further tailoring to specific installations. The result is a very versatile amplifier capable of both basic upgrades and demanding fully active systems. Despite the high power, the amplifier maintains stability, low distortion and excellent control over speakers. The brushed aluminum chassis ensures efficient heat dissipation and high mechanical durability. The design is enhanced by a recessed glass logo with backlighting, underscoring Musway's attention to detail and build quality.
Advanced DSP tuning and full control over the sound
At the heart of the amplifier is a powerful DSP processor from Analog Devices combined with high-quality Burr-Brown converters, representing a proven and highly capable platform also used in standalone processors. The current generation uses 512k Bit DSP technology with expanded memory and the new Tunest software, which brings broader configuration options and a more intuitive interface. A fully parametric 31-band equalizer is available for each channel, active crossovers with slopes up to 48 dB/oct., time alignment in fine steps and precise level control. A new extended input equalizer including high-shelf, low-shelf and all-pass filters allows even finer signal optimization at the input. Fully configurable input and output routing provides maximum flexibility in system design.
Control and expandability
The M6 supports a wide range of accessories that significantly expand the capabilities of the entire system. Bluetooth modules are available for wireless music streaming, in both a standard version and a variant with aptX HD support for high-resolution streaming. The Bluetooth module also serves for complete DSP configuration via a mobile app or PC software. For in-drive control Musway offers two remote control variants – a classic remote for basic functions and the advanced myCON controller, awarded the prestigious EISA prize. It enables detailed control of DSP functions via a display, profile switching, source selection and complete sound control directly from the driver's seat.
Ready for modern vehicles and advanced integration
The amplifier is equipped with a wide range of inputs including low-level RCA, high-level inputs, AUX and an optical digital input, enabling integration into virtually any vehicle or audio system. Auto Turn-On on signal detection means the amplifier can be used in modern cars without a classic REM signal. The EPS® protection system eliminates error messages from factory radios and ensures trouble-free operation, while the high-level mixing function preserves important system sounds such as parking sensors or navigation prompts. IFT (Interference Free Technology) minimizes electromagnetic interference and helps maintain clear radio reception.
Awards in expert tests
Musway amplifiers have long been among the highest-rated products in their class and the M6v4 clearly confirms this position. In addition to the EISA award mentioned above, the amplifier received an excellent score of 1.1 in the Spitzenklasse category in a test by the German magazine Car&Hifi, along with Best Product and EMV-Tipp awards. The editors also named the M6v4 Product of the Year 2025 in the DSP amplifier category. The test highlights the significant power increase, very low distortion even at lower power levels, and an overall clean, clear and dynamic sound. "The amplifier offers extraordinarily versatile use and, thanks to the combination of power, DSP functions and connectivity, ranks among the most comprehensive solutions on the market."

| Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers. | D |
| Number of amplifier channelsAmplifiers are divided into: - Monoblocks - 2-channel - 3-channel - 4-channel - 5-channel - 6-channel - multi-channel Each channel is used to power one speaker for the coaxial type, or one side if they are component speakers. Monoblock type amplifiers are mainly used for subwoofers. 2-channel are suitable for both subwoofers and, for example, the front pair of speakers in a car. 3-channel is used for front or rear speakers + subwoofer. 4-channel are used for front + rear speakers or 1 pair of speakers + subwoofer. 6 or 5-channel are used for 2 pairs of speakers + subwoofer, most often. Bridging means connecting the amplifier to a bridge, using the + pole from one channel and the - pole from the other channel. In most cases this is shown as "BRIDGED" on the amplifier. | 4 |
| RMS power into 4 ΩRMS power when loading speakers or subwoofer at 4 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier. | 6 x 80 / 3 x 260 W |
| RMS power into 2 ΩRMS power when loading speakers or subwoofer at 2 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier. | 6 x 130 W |
| Speaker impedance | 2 – 8 Ω |
| Frequency rangeThe ability of the amplifier to reproduce the signal from the lowest frequency to the highest = faithfully reproduce the sound in a specific frequency band. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. Since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even specify this maximum tolerance of sound pressure in decibels in their catalogs for reasons of prestige. Data impoverished in this way is unfortunately worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness or undulation of the frequency curve in good speaker systems for high-quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural. | 10 – 20000 Hz |
| Harmonic Distortion (THD)Total harmonic distortion indicates how much the input signal is distorted in the amplifier. Distortions appear as overtones contained in the output signal. The proportion of originally absent parts of the signal is given as a percentage, typical values are between 0.001% and 0.5%. Distortion is measured in their power band. If it exceeds the limit of 0.7% from a certain power, it is the value of the output power of the given amplifier, from which it no longer plays without distortion and from which the distortion usually increases steeply, so that no further increase in power can be counted on. The lower the value, the better. | 0.014 % |
| Signal-to-noise ratioThe signal-to-noise ratio means that the output signal always contains noise. The signal-to-noise ratio expresses how much of this noise is compared to the useful signal. The so-called A value is given, which does not take deep and very high frequencies into account. This corresponds to the characteristic of human hearing, which is not so sensitive to deep frequencies, especially below 1 kHz. The higher the value, the better the amplifier is. | 94 dB |
| Inputs | 6 x RCA, 6 x high-level, AUX, SPDIF |
| Outputs | 2 x RCA, 6 x speaker-level |
| Input sensitivityIn order for the amplifier to perform its function correctly, it requires an input signal of a certain level, which is different for car radios. It is measured in "Volts" (e.g. 2 V, 4 V, etc.) The higher the value at the output of the pre-amplifier, or car radio, the less demands are placed on the power of the amplifier. However, the amplifier must allow this input sensitivity, and for that reason this value is also given for the amplifier. | High-level: 3 V – 21 V, RCA: 1.5 V – 4.5 V |
| Input impedance | 13 Ω (High-level), 47 kΩ (RCA) |
| Bass boostBass boost or bass enhancement. With this function, the bass itself can be emphasized, at a high level of bass boost, the speakers and the subwoofer can distort a lot and the sound will be worse than better. We therefore recommend using the "bass boost" function wisely. With maximum use of bass boost, there is a risk of damage to the speakers and thus to the subwoofer. | 0 – 12 dB @ 45 Hz |
| Damping factorDF - Damping Factor . It is the ratio of the load (repro + cables, crossover, etc.) to the internal resistance of the amplifier. The bigger the DF, the more controlled the bass. Amplifiers with a lower DF tend to hum. Subwoofers with a higher Q in the bass reflex and sometimes in the enclosure will also cause humming. | > 70 |
| Phase shiftPhase shift is a linear electronic oscillator that produces a sinusoidal output. It consists of an inverting part of the amplifier such as a transistor. The feedback network "shifts" the phase at the output of the amplifier by 180 degrees to the oscillation frequency and gives positive feedback. The Phase shift filter produces a phase shift that increases with increasing frequency. This is usually used when the subwoofer sub-assembly is out with the magnet, or when two amplifiers are connected externally. Phase Shift is also used with active speaker wiring, where the time shift of the speakers is set. The point is that the subwoofer does not play the bass late, and for this reason better amplifiers offer this phase reversal option. | 0 – 180° |
| Standby power consumption | 1.2 A |
| On-board voltage rangeThe ability of the amplifier to operate at a specified voltage. As the voltage decreases, so does the power of the amplifier. The ideal voltage in a car is between 13.8 and 14.4 V. | 7.5 – 16.7 V |
| The value of the fuses on the amplifierFrom the value of the fuses on the amplifier, you can get a true picture of the real performance of the amplifier. | 1 x 40 A |

| Socket input terminalsFerrule terminals allow better wiring contact to the amplifier. It is also a more secure form of terminals. If you are tightening the sleeve terminals, we recommend retightening them after 1 day, as the connected cable gradually compresses. | Yes |
| Input for wired remote controlIf the amplifier has a remote control input. | Yes |
| Remote control included in the packageSome models of amplifiers also come with wired remote controls in the package, which on one side plug into the amplifier and on the other side you have a potentiometer that you can place anywhere in the cabin. A common place to place the remote control is under the steering wheel. The advantage is the regulation of power, and therefore volume, depending on driving conditions and the mood of the crew in the car. | No |
