The GPX500.2 amplifier from the GPX series is Crunch's promotional offering in the entry-level two-channel amplifier segment. The quality and features offered at this price point make it one of the most compelling offerings on the market.

The GPX500.2 model is a two-channel amplifier operating in class A/B. It has a number of advanced functions available in much more expensive models, which makes its use universal.

Thanks to its built-in active crossovers and configurability, it is suitable for powering both a pair of speakers and a subwoofer.

Used to power a pair of speakers.
Built-in high-pass crossovers can be used. High-pass crossovers cut off the lowest frequencies that speakers, especially those with smaller diameters, don't reproduce, significantly burdening them and causing sound distortion. Crossovers ensure clear and pleasant sound. The ability to boost high frequencies makes them more audible, especially if the speakers are mounted at the rear or low in doors.

It's used to power a subwoofer.
The amplifier can be bridged, combining the power of the left and right channels to power a single woofer. The built-in low-pass crossover allows for the correct frequency response adjustment to ensure the subwoofer receives sound with the appropriate frequency response.
In this configuration, the low-pass crossover cuts off high frequencies not handled by the subwoofer, preventing it from overheating unnecessarily and using all its power to process the bass. Additionally, there's the option to boost low frequencies.

Easy configuration and settings, at a very attractive price, make it an excellent option for beginners starting their adventure with music in the car.
