Musway ONE600 Amplifier
Musway ONE600 is a Class D monoblock designed for modern car audio systems where emphasis is placed on high power, compact dimensions and installation flexibility. The amplifier offers up to 650 W RMS (at 1 Ω), enabling the powering of one or more powerful subwoofers with adequate headroom. The construction and chassis design in brushed aluminium follows other Musway amplifiers, so it can be ideally combined, for example, with the brand's DSP amplifiers or standalone processors to create powerful multi-channel systems. Despite its very compact dimensions, the ONE600 is among the most powerful monoblocks in its class. Another major advantage of the amplifier is its seamless integration into today’s vehicles. IFT (Interference Free Technology) minimizes electromagnetic interference and helps preserve clear radio reception, while the EPS (Error Protection System) protects the amplifier from operational faults. The unit is of course ready for vehicles with start-stop systems and can be connected via RCA or high-level inputs. The package includes a compact remote control for adjusting the subwoofer gain.
High power in a compact body
The amplifier is built in a robust aluminium chassis with a brushed aluminium heatsink, which ensures efficient heat dissipation and high mechanical durability. Thanks to its compact dimensions, the ONE600 is among the smallest amplifiers in its power category and can be installed even in very limited spaces. Despite its size, it offers 250 W RMS at 4 Ω, 400 W RMS at 2 Ω and 650 W RMS at 1 Ω, making it an ideal amplifier for powering a subwoofer in both standard and more powerful installations. Thanks to a very high damping factor exceeding 750, the amplifier provides excellent control over the subwoofer cone movement, resulting in firmer, faster and more precisely defined bass.
Flexible tuning with the option to disable filters
The ONE600 offers a complete set of filters required for proper subwoofer tuning. Available are an adjustable subsonic filter, low-pass filter, phase control and adjustable bass boost. This allows the amplifier to be very well adapted to the specific installation and the installed subwoofer. A unique feature of the amplifier is the ability to completely disable all filters. In Pure Amplification mode the amplifier operates over the full frequency range up to approximately 1 kHz, so it can be used as a pure power stage, for example in conjunction with an external DSP processor or active systems.
Prepared for modern vehicles
The amplifier is equipped with both low-level RCA inputs and high-level inputs for direct connection to factory head units. Automatic turn-on when signal is detected is standard, so the amplifier can be used without issues even in modern vehicles without a classic REM signal. IFT (Interference Free Technology) minimizes electromagnetic interference and helps preserve clear radio reception, while the EPS (Error Protection System) protects the amplifier from operational faults. The amplifier's design is also prepared for vehicles equipped with start-stop systems.
Awards in professional tests
Musway amplifiers are regularly very positively rated in professional magazine tests. The ONE600 model received an overall rating of 1.3 in the Oberklasse (higher class) category and an award for very good price/performance ratio in a test by the German magazine Car&Hifi. The test praised especially the clean and stable power, compact construction and balanced sound, which make the amplifier great for everyday installations as well as more powerful systems. The amplifier also received the EMV-Tipp award for very low electromagnetic interference and trouble-free radio reception even when installing a powerful amplifier.

About the brand
MUSWAY is an abbreviation of the motto „Music is the Way“ – music is the way. The brand was born out of a passion for high-quality sound reproduction and achieved its first notable successes with high-quality Hi-Res audio players and digital signal processors. The real breakthrough came with the introduction of the first Class D amplifiers with integrated DSP, which gradually ranked among internationally acclaimed products in professional magazine tests and received a number of prestigious awards, including EISA. Since 2015 the brand's development has been anchored in Germany, where product design, technical tuning and final concepting of individual models take place. Musway has gradually built a reputation as a manufacturer of compact, technically advanced yet musically natural components that combine modern digital technologies with an emphasis on clean and linear sound. The portfolio today includes standalone and DSP amplifiers, speakers and subwoofers, with each new generation building on the brand's philosophy – to offer the maximum musical experience without compromises in technology, functionality or workmanship.

| 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. | 1 |
| 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. | 250 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. | 400 W |
| RMS power into 1 ΩRMS power when the subwoofer is loaded at 1 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier. When connected to 1 Ω, significant heating of the amplifier may occur. | 750 W |
| Speaker impedance | 1 – 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. | 6 – 1250 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. | < 0.05 % |
| 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. | 91 dB |
| 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. | 5 – 0.2 V |
| Low-pass filter (LPF)LPF / LP or "low pass filter" offers the possibility to adjust the amplifier using a potentiometer so that the lower band plays only the frequencies in a certain band that you need. This filter is used to adjust the frequency range for the subwoofer, so that it does not overload or distort the sound. Example: Amplifiers most often have an LPF from 20 to 300 Hz. We recommend setting this potentiometer in the range of 45-80 Hz. | 40 – 150 Hz |
| SubsonicA subsonic filter is essentially a high-pass filter for very low frequencies, typically 45 Hz or lower. Anything below this setting is weakened. The point is that the subwoofer does not go below the subsonic filter setting and does not overload itself with very low frequencies. A useful function, if set correctly, the subwoofer is not overloaded. | 10 – 40 Hz |
| 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 – 18 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. | > 750 |
| 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° |
| 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 50 A (external) |
| High level inputsThe high-level input on the amplifier allows connection directly to the existing speakers in the car without additional purchase of an external high/low adapter. Important equipment in the case of installing an amplifier on an original car radio. | Yes, with EPS function |
| Automatic on and offThis function allows you to automatically switch on the amplifier. | Yes |
| 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. | Yes |
