The Gladen RC 70c4 is a four-channel car amplifier designed to bring more power and clarity to your vehicle's audio system. Operating as a Class A/B amplifier, it delivers 68 W RMS per channel at 4 Ohms, which can increase to 105 W RMS when using 2 Ohm speakers. For those needing more punch, the channels can be bridged to provide 2 x 210 W RMS in mono mode, making it versatile enough to drive both a set of door speakers and a subwoofer. This unit handles a frequency range from 20 to 20,000 Hz with a signal-to-noise ratio of 95 dB, ensuring a clean sound with minimal interference. It features a high-level input with Auto Sense, allowing you to connect it to factory head units without needing a dedicated remote turn-on wire. Internally, the amplifier is built on a double-side PCB with SMD components for reliability, and it includes thermal protection that triggers at 80 °C to keep the hardware safe during intense use. Measuring 283 x 150 x 50 mm and weighing 2.2 kg, the RC 70c4 has a compact footprint that fits easily under a seat or in the trunk. Its input sensitivity ranges from 0.2 to 10 V, giving you flexibility in how you tune the gain to match your source signal.
