Boss ARMOR AR4000D Amplifier Car Stereo
The Boss ARMOR AR4000D Amplifier Car Stereo is the ideal amplifier for small spaces requiring big power. Designed with a slimmer chassis, the Boss ARMOR AR4000D Amplifier Car Stereo is a Class D Monoblock Power Amplifier with a 4000W of power, remote subwoofer control and variable bass boost. Nickel-plated RCA level inputs and screw terminals deliver high-quality audio signals, and 3-way protection circuitry (thermal, overload, and speaker short protection) help avoid blowing up your speakers; Soft start turn-on softens the initial sound production so your eardrums won’t blow out, either. The combination of powerful performance and convenient installation of the ARMOR is hard to find, making the Boss ARMOR AR4000D Amplifier Car Stereo the right amp for delivering incredible bass with limited space.

- Slim design; makes it easier to deliver powerful bass with limited space
- High-quality protection; 3-way protection circuitry and a heavy duty aluminum alloy heat-sink keep the amp safe while enjoying its pure bass performance
