Compact Stability
Enjoy superior stability and sound with the Planet Audio Pulse PL4000.1D Monoblock Class D Amplifier. With 4000 Watts Max Power and MOSFET power supply, this Amplifier offers stable, powerful Bass for your playlists. Customize the sound with Variable Low Pass Crossover, Bass Boost, Subsonic Filter, Phase Control and Remote Subwoofer Control. Strap this Amplifier to another PL4000.1D for double the performance. When space is limited but your passion for great sound is not, Pulse Amplifiers with blue illuminated end panel strips and logo are just what the doctor ordered to power up your music and get your heartbeat racing.

Class D and MOSFET
Class-D amps run more efficiently and generate more power using a more compact design than traditional Class A/B amps.

Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output.

Strapping Capability and 1 Ohm Stable
Strap two amplifiers together to get double the power at an impedance of 2-Ohms.

1-Ohm stable gives you maximum power for superior wattage and performance without overheating. The greater the power the more current drawn from your vehicle's electrical system.

Variable Low Pass Filter and Subsonic Filter
Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.

Subsonic filter restricts low-frequencies below the specified setting for better subwoofer protection and performance.

Subwoofer Level Control and Bass Boost
A wired remote lets you easily control the subwoofer level for customized output and superior sound.

Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.

Pre-Amp Outputs and Low Level Inputs
This unit's Pre-Amp outputs let you expand your system by adding one amp or signal processor.

Low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to units equipped with RCA Pre-amp outputs.

Short Protection and Phase Control
Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short.

Phase control lets you switch the speaker phase with the amp if your speakers or subwoofer are hooked up 'out of phase'.

Variable Input Control and Switchable Input Sensitivity
The Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly.

Switchable input sensitivity provides adjustable control over the input signal from the head unit to achieve customized balance between power and sound quality.

LED Illuminated Logo and End Panels
The Planet Audio Logo has blue backlit illumination and the End Panels have blue illuminated light strips.
