Review: Fotos principales no conciden con las del producto.,.... No lo eh instalando pero a como lo veo no creo haber hecho una buena compra ... Dejó la foto de como se muestra y la otra en dibujo como llego
Review: Powers my 10 inch home theater car subwoofer with the right amount of power. Easy to adjust gain controls and is powered by a 12 volt power supply I also reviewed on here. Great match of power, small and compact. Well worth the money. Sound quality is punch and perfect for my subwoofer. Took 10 minutes to install and works great!

## 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

*by M***Y on 24 February 2025*

Excellent power for running a single subwoofer. I would not hesitate to use it on a ported 15. No, it won't blow the doors off your car obviously. But for the price it has a remote level control and subsonic filter. It "feels" like it puts out an honest 150 watts. For 85$ you won't find anything better and it's extremely compact 👍
