## Description

amplifier car audio Monoblock Class D Compact Subwoofer Amplifier, 2/4 Ohm Stable, Low/High Level Inputs, Low Pass Crossover, Mosfet Power Supply

## Features

- Car audio amplifier 450 watts RMS at 2-ohm load (14.4v); 300 watts RMS at 4-ohm load (14.4v);
- Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
- 2-4 Ohm Stable - Able to continuously power loads of 2-4 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
- Engineered to be the most efficient car monoblock amplifier in its class so that you can get the most out of your vehicle’s electrical system
- MOSFET pulse width modulated power supply and proprietary heat dissipation design will ensure the amplifier for car subwoofers runs cool for even the most demanding playlists
