CRUNCH GTX1500.1D – Class D Digital Mono

CRUNCH GTX1500.1D – 1-channel GRAVITY MINI power amplifier with bass remote control

Crunch is known for always offering a large selection in its amplifier series. The Gravity series optimized for the smallest size is no exception here. With an extremely compact construction of just 135 mm width and 48 mm height, it starts with 10 models. But the real surprise is in the performance: From the ultra-compact heatsinks, Crunch gets enormous power up to 1500 watts of RMS! The Gravity models owe their impressive performance to the efficient Class D technology, which is used in all variants. Another highlight is the excellent value for money. Nothing was spared: In addition to high performance, the amplifiers offer a standard set of equipment – including remote control for bass level in all models. A special design element is the recessed acrylic frame on the top, the red CRUNCH logo and the white model designation come into their own in a stylish way in the 2-colour lighting – a real eye-catcher in any installation. In edition 3/2025 of the test magazine Car&Hifi, three of these amplifiers have been thoroughly tested. Initially, the GTX1600.4D and GTX2250.1D models were awarded Best PRODUCT in their respective categories, while the GTX1200.2D was honored with the coveted sound tip!
