CT-80.4D // 480 Watts RMS 4-Channel Car Audio Amplifier
CT Sounds engineered the CT-80.4D Full-Range Class D Multichannel Car Amplifier for anyone in need of a powerhouse amplifier that fits just about anywhere in your vehicle and won’t destroy your wallet. If you want to do 70 mph down the highway with the windows down and still have crisp and clear sound over the wind noise then look no further.
This multi-channel amplifier features a Low Pass Filter (LPF) and Subsonic Filter so you can get the exact sound you are looking for out of your amplifier. The MOSFET power supply and proprietary heat dissipation design will ensure that the amplifier runs cool for even the most demanding playlists. Furthermore, the compact chassis and small footprint make it easy to install in any car audio application.
You can sleep easy at night knowing your amplifier is protected from damage due to the amplifier's uniquely engineered protection circuitry featuring high voltage, low voltage, over current, and high-temperature protection.
