The GLADEN RCore 1|600 is a Class D mono car amplifier designed to integrate subwoofers into your vehicle's audio system. It delivers 395 W at 4 Ohm and increases to 620 W when running at 2 Ohm, providing a stable power source for low-frequency drivers within a frequency range of 10–220 Hz. To fine-tune the sound, the chassis features analog controls for a low-pass filter adjustable from 40 to 220 Hz and a subsonic filter between 20 and 50 Hz, both with a 24 dB/oct slope. You can further shape the bass response using the -6 / 0 / +6 dB boost adjustment. The unit supports both high-level inputs (0.4–10 V) and low-level inputs (0.2–5 V), making it compatible with either factory or aftermarket head units, and it can turn on automatically via a high-level signal. Measuring 198 x 150 x 52 mm, this compact amplifier fits easily into tight spaces while remaining protected by a 40 A external fuse. It is built to handle modern vehicle electronics, including support for Start/Stop systems by maintaining operation at 7.5 V for up to 3 seconds. For those who prefer adjusting their bass levels from the driver's seat, the amplifier is compatible with the RTC.2 remote controller.
