Amplificador subwoofer monobloque clase D, 500 W
RD500/1
Amplificador de subwoofer monobloque clase D, 500 W x 1 a 2 Ω / 250 W x 1 a 4 Ω - 14,4 V
Nacido para producir la friolera de 500 vatios en 2 ohmios (14,4 V, 1 % THD), el amplificador RD500/1 fue diseñado para generar toneladas de pura felicidad de subwoofer desde un chasis elegante y ultracompacto. El secreto detrás de su competencia energética es nuestra tecnología de conmutación patentada NexD™, que ofrece grandes cantidades de potencia de salida con eficiencia precisa y distorsión ultrabaja.
Para su comodidad, los controles del RD500/1 están ubicados en la parte superior del amplificador, debajo de una cubierta protectora, y todas las conexiones se encuentran a lo largo de un lado de su chasis. Las características de procesamiento de señal incluyen un filtro de paso bajo de 12 dB/octava, con selección de frecuencia continuamente variable de 50 a 500 Hz y un ecualizador de refuerzo de graves variable. También se encuentran disponibles entradas balanceadas diferencialmente de rango dual, capaces de aceptar la mayoría de los niveles de voltaje de entrada. La capacidad de encendido automático (mediante detección de señal o detección de compensación de CC) es estándar, junto con un conjunto de salidas de preamplificador para que pueda pasar señales fácilmente a otro amplificador.
El RD500/1 también está equipado con un indicador de recorte LED integrado. Esta característica completamente nueva e innovadora le permite configurar fácilmente la configuración de sensibilidad de entrada de su amplificador, de manera rápida y precisa, sin necesidad de equipo especial. El RD500/1 cuenta con un acabado duradero con recubrimiento en polvo negro y una tira de luz LED de dos colores montada en la parte superior que informa el estado y la condición general. Con la adición de un control de nivel remoto RBC-1 (se vende por separado), puede controlar la salida del subwoofer directamente desde el asiento del conductor.

What Others Are Saying
Eddie was great - SDCS installed a new head unit in my 2019 4Runner. He was honest in his opinions regarding the options I was considering. Pricing was also good - he was able to reuse some of my existing installation kit so I saved a bit of $$.Installation was clean and fast and he took the time to walk through the features before I left. Highly recommend!!
I had a great time at this shop! The staff really knows their stuff and took the time to explain the different options without pressure. Installation was quick, clean and professional. Everything looks factory and sounds amazing. The prices were fair and customer service was above and beyond. I highly recommend this place if you're looking for quality car audio and excellent service.
Those guys are really professional! I had a new Alpine floating head unit installed in my 2008 Mercedes, and it feels like a brand-new car. The installation was super clean. At first, the sound wasn’t the same as the factory stereo, but Kevin tuned it to be just as good—if not better—without adding any new amps. They even used my factory GPS antenna so I don’t have extra wires hanging out. On top of that, they matched the online price. Big thanks to Kevin and Eddie—highly recommended!
Kevin was awesome, he took his time and explained everything to me. I went in initially for a dash cam install and then decided to get a sub and amp installed as well. Both turned out great and will be returning if I need more work done.
Came In not knowing what to expect when suddenly my stereo stopped working. Spoke with Kevin in the front and after a VERY fast diagnosing they discovered my wiring was incorrect. After only about 45 minutes total being in the store I was on my way to the beach with a working stereo again! Thank you so much SDCARSTEREO
Highly recommend Kevin and the team at San Diego Car Stereo for any issues with aftermarket stereos. I bought a car with an aftermarket stereo and AC unit that wasn’t working properly—specifically, the heat wasn’t functioning due to an improper setup. I had several people look at it with no luck, and even the dealership basically refused to help because it was an aftermarket install. I came to Kevin and his team over the holidays feeling pretty defeated, but he was confident he could get the heat working before I headed back to a Colorado winter. Sure enough, he got it done.
