The GLADEN RC 105c4 is a 4-channel Class A/B car amplifier designed to bring clear and powerful sound to your vehicle's audio system. It delivers 4 x 105 W RMS at 4 Ohm, though you can bridge the channels to achieve 2 x 300 W RMS for more demanding speakers. With a frequency response spanning 20 to 20,000 Hz and a signal-to-noise ratio of 99 dB, it ensures a clean audio reproduction across the entire audible spectrum. Inside the 357 x 150 x 50 mm chassis, the amplifier utilizes a double-sided PCB and SMD components to maintain efficiency and reliability. The unit weighs 3.3 kg and includes thermal protection that triggers at 80 °C to keep the hardware safe during intense use. For easier installation, it features high-level inputs with Auto Sense, and you can add an optional remote control module if you need more direct management of your volume levels.
