Musway TWO100 Amplifier
The Musway TWO100 is a compact 2-channel Class D amplifier that stands out primarily for its exceptional power-to-size ratio. Despite its very small dimensions it delivers up to 2 × 200 W RMS at 2 Ω or 400 W RMS bridged, ranking it among the most powerful mini amplifiers in its class. The design is based on Musway’s modern platform with emphasis on high efficiency, stable power and seamless integration into contemporary vehicles. The integrated new Smart Control System from Musway manages optimal operating temperature and power while also acting as overload protection. Thanks to IFT (Interference Free Technology) there is no interference with radio or other systems, while the EPS (Error Protection System) safety system ensures reliable operation even when connected to factory head units.
Compact size, surprising power
The TWO100 is one of the smallest amplifiers in its category, yet it offers power typically found in much larger units. In real measurements it reaches roughly 120 W RMS at 4 Ω and more than 200 W RMS at 2 Ω per channel, which confirms its high power density and ability to drive not only front component systems but also smaller subwoofers. Thanks to bridged operation the amplifier can also be used as a compact monoblock for a subwoofer, significantly expanding its use in installations with limited space. A high damping factor exceeding 200 contributes to precise speaker control, resulting in tighter, faster bass and better midrange definition. Very low distortion (around 0.007 % THD+N) confirms that this is not just a power amplifier, but a device capable of preserving detail and control in reproduction
Flexible tuning
The amplifier is equipped with switchable high-pass and low-pass filters in the 50 – 250 Hz range and a bass boost of up to +12 dB at 45 Hz. This makes the TWO100 easy to adapt for driving speakers as well as a subwoofer. It also features stereo/mono mode, high-level inputs with automatic turn-on and simple integration into modern vehicles without the need for a REM signal. A practical addition is the remote bass level control.
Ready for modern vehicles
The amplifier includes both low-level RCA inputs and high-level inputs for direct connection to factory head units. Automatic turn-on upon signal detection means the amplifier can be used without issues in modern cars lacking a classic REM signal. IFT (Interference Free Technology) minimizes electromagnetic interference and helps maintain clear radio reception, while the EPS (Error Protection System) safeguards the amplifier against operational faults. The amplifier’s construction is also prepared for vehicles equipped with start-stop systems.
Awards in expert tests
Musway amplifiers are regularly rated very positively in expert magazine tests. The TWO100 model received an overall rating of 1.5 in the Spitzenklasse (top class) category in a test by the German magazine Car&Hifi. Reviewers were particularly impressed by its dynamics and control. "The bass component is firm, fast and precise, without unnecessary ringing, while the midrange remains clean and natural. The amplifier handles both energetic music and detailed reproduction, where its ability to render subtle nuances and space shines through, and it earns praise for a very good price/performance ratio." The amplifier also received the EMV-Tipp award for very low electromagnetic interference and trouble-free radio reception even when installing a powerful amplifier. Additionally it was awarded the “Klangtipp” by the editorial board for exceptionally high-quality sound in its price category. The complete review can be read at the link.

| 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. | 2 |
| 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. | 2 x 115 / 1 x 400 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. | 2 x 200 W |
| Speaker impedance | 2 – 4 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. | 15 – 22000 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. | < 0.012 % |
| 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. | > 100 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. | High-level: 1.5 – 20 V/RMS, RCA: 0.45 – 6 V/RMS |
| High pass filter (HPF)HPF / HP or The "hi pass filter" offers the option of setting the amplifier using a potentiometer so that medium, possibly mid-bass and treble frequencies play upwards from a certain frequency. Example: Amplifiers most often have an HPF from 40 to 300 Hz. If we set the potentiometer to a value of approx. 150 Hz, the sound will be clipped so that it plays frequencies from 150 Hz up to the maximum upper limit of the entire frequency range of the amplifier, perhaps up to 20,000 Hz. We recommend setting this potentiometer in the range of 80-160 Hz. Thanks to this setting option, the speakers can handle a higher performance, as you will not overload them with bass in the lower frequency range. | 50 – 250 Hz |
| 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. | 50 – 250 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 – 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. | ≥ 220 |
| 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. | 8 – 15 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 |
| 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 |
