4-Channel Car Amplifier with Class D Power, Adjustable Filters and Compact 1000-Watt RMS Audio Setup

The CT-150.4D four-channel car amplifier delivers configurable power for vehicle audio systems in a compact chassis. Its Class D circuitry, adjustable gain and built-in crossover controls help you tune full-range or bridged amplifier setups for your listening preferences.

A MOSFET pulse-width-modulated power supply, soft turn-on circuit and LED power/protection indicators support practical installation and operation. High- and low-voltage, thermal, over-current and speaker-short protection circuits are built in for added system protection.

CT Sounds specifies 250 watts per channel at 2 ohms, 150 watts per channel at 4 ohms, or 475 watts x 2 when bridged at 4 ohms. The amplifier uses 4-gauge power and ground inputs and 12-gauge speaker inputs.
