Amplificador subwoofer monobloque clase D, 250 W
JD250/1
Amplificador de subwoofer monobloque clase D, 250 W x 1 a 2 Ω / 150 W x 1 a 4 Ω - 14,4 V
Diseñado para producir unos saludables 250 vatios en 2 ohmios (14,4 V, 1 % THD), el amplificador JD250/1 es una gran solución para alimentar subwoofers en un sistema económico. Nuestra tecnología de conmutación patentada NexD™ ofrece grandes cantidades de potencia de salida real con excelente eficiencia y distorsión ultrabaja.
Los controles del JD250/1 están ubicados en el panel de entrada, mientras que las conexiones de alimentación y altavoces se pueden encontrar en el extremo opuesto de su chasis de aluminio extruido. 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 hay disponibles entradas balanceadas diferencialmente de rango dual, capaces de aceptar señales de nivel de línea y de altavoz. 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 JD250/1 también está equipado con un anillo indicador de recorte LED integrado que rodea el control de sensibilidad de entrada. Esta útil función le permite configurar fácilmente la sensibilidad de entrada de su amplificador, de forma rápida y precisa, sin equipo especial. Con la adición de un control de nivel remoto RBC-1 (se vende por separado), puede controlar el nivel del subwoofer 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.
