This 2-channel amplifier delivers 140 Watts per channel at 4 Ohms and 250 Watts at 2 Ohms, with 450 Watts available at 4 Ohms in bridged mode. Thanks to advanced Class-D technology, the amplifier achieves an efficiency of up to 88%, making it an extremely efficient device. The high power combined with efficiency makes the QM500.2 ideal for demanding audio applications in vehicles that require powerful yet compact solutions.

What are the dimensions of the Quantum QM500.2?

The Quantum QM500.2 Amplifier from ESX is designed to be compact for easy installation in the vehicle. Its dimensions are 190 mm in width, 35 mm in height, and 112 mm in depth. These small dimensions allow for flexible placement in the vehicle, even in tight installation conditions. The compact size is made possible by a solid aluminum housing that is not only robust but also contributes to efficient heat dissipation, which is an important factor for the longevity of the amplifier.

What input options does the Quantum QM500.2 offer?

The ESX Quantum QM500.2 Amplifier is equipped with multiple input options that allow for versatile integration into your existing audio system. It offers both RCA inputs and high-level inputs via a wiring harness. This flexibility allows for connection to both conventional car radios and factory systems with high-level outputs. Additionally, the Error Protection System is employed to ensure the safety and stability of the connection. An automatic turn-on feature makes handling particularly convenient.

How does the automatic turn-on feature of the Quantum QM500.2 work?

The Quantum QM500.2 Amplifier features an automatic power-on function that activates the amplifier as soon as an audio input signal is detected. This is particularly useful in vehicles with factory systems, as no separate remote wire is required. The amplifier can thus be connected directly to the high-level output of the car radio and starts automatically as soon as music playback begins. This function not only enhances user convenience but also significantly reduces installation effort by eliminating the need for additional cables.

What protection mechanisms does the Quantum QM500.2 have?

The ESX Quantum QM500.2 is equipped with a triple protection circuit that includes essential safety features. These include overheat protection, overvoltage protection, and short circuit protection. These mechanisms ensure that the amplifier is safely turned off in the event of unusual operating conditions to prevent damage. Another highlight is the Error Protection System in the high-level input, which provides protection in case of misconfigurations. Overall, these features significantly enhance the reliability of the amplifier.

How is the bass level remote control of the Quantum QM500.2 used?

The compact bass level remote control of the Quantum QM500.2 allows for convenient adjustment of the bass level directly from the driver's seat. This handy control unit can be mounted in an easily accessible location in the vehicle and is connected to the amplifier via a cable. It enables you to precisely adjust the bass level according to music genre or personal preference. This is particularly practical for quickly adapting the sound to different listening situations without having to change the main settings of the amplifier.

What crossover options does the Quantum QM500.2 offer?

The ESX Quantum QM500.2 Amplifier is equipped with flexible crossovers that provide a variety of adjustment options. The high-pass filter (HP) can be set between 10 and 500 Hz, while the low-pass filter (LP) operates in the range of 50 to 5000 Hz. Additionally, there is the option to use the bandpass mode, which further specializes the frequency selection. With these options, the sound characteristics of the system can be optimally adjusted to the speakers to achieve the best possible sound performance in the vehicle.

What compatibility does the Quantum QM500.2 offer with existing audio systems?

The Quantum QM500.2 Amplifier from ESX is particularly suitable for integration into existing audio systems, including factory setups. Thanks to its high-level inputs, it is compatible with vehicles that do not have pre-outs on their factory radios. The compact design with dimensions of 190 x 35 x 112 mm allows for easy installation in tight spaces. Additionally, the automatic power-on feature supports seamless operation without additional wiring of remote lines. The comprehensive compatibility makes it an ideal choice for many vehicle models.

What design does the Quantum QM500.2 Amplifier have?

The Quantum QM500.2 from ESX is equipped with a solid aluminum housing that serves both as a robust protective casing and supports effective cooling. The side panels are made of die-cast aluminum, providing additional stability and improving heat dissipation. The compact yet sturdy design contributes to the durability and reliability of the amplifier, even under heavy use. The high-quality components are audiophile-tuned to ensure outstanding sound quality, making the QM500.2 particularly attractive to sound enthusiasts.

What advantages does Class-D technology offer in the Quantum QM500.2?

The Class-D technology in the Quantum QM500.2 Amplifier from ESX offers numerous advantages, both in terms of efficiency and sound quality. The high efficiency of up to 88% results in low heat generation and maximum utilization of input power for music playback.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
