Planet Audio BBD4000 4000 W Class D Monoblock Car Amplifier, 1 Ohm Stable

  

Boost the power behind your bass with the Planet Audio BBD4000 Monoblock class D amplifier. With 4000 high output max power and MOSFET power supply, this amplifier offers stable, powerful bass at 1 Ohm. Customize the sound with variable low pass crossover, variable bass boost, variable subsonic filter, phase control and remote subwoofer control. Strap this amplifier to another BBD4000 for double the performance and power.

Class D, MOSFET power supply, Fuse quantity (1) 250 amp ANL blade. Low level inputs, soft turn on circuit, power, and protection LEDs. Thermal overload speaker and short protection, Subwoofer level control. Phase shift selector 180º, variable subsonic filter 10-50 Hz. Variable low pass crossover 50-250 Hz, variable bass boost 0 - 18 dB.

Variable input gain control, input sensitivity selector, speaker impedance 1-8 ohms. S/N Ratio 67 dB, frequency 10-250 kHz. Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. 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. This comes in handy if you are installing your subwoofer with the magnet facing out.

Reverses the polarity (Positive/Negative) on your subwoofer terminals to reverse the direction of the low frequency BOOM that you are used to hearing. Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short. A wired remote lets you easily control the subwoofer level for customized output and superior sound. Switchable input sensitivity provides adjustable control over input signal from the head unit to achieve customized balance between power and sound quality.

The Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly. Class-D amps run more efficiently and generate more power using a more compact design than traditional Class A/B amps.
