Good Bass nice performances in Budget.
Easily I didn't feel much difference in the sound quality later on when I started hearing the song which I used to hear before installing this sub. Huge difference was noticed... I am satisfied really. For the cost and consuming very less space

Me encantó
Lo recomiendo ampliamente. Lo instale en mi Suzuki swift 2019 debido a que el audio deja mucho que desear a volúmenes altos. Mi intención era quitarle bajos a las bocinas incluidas en mi auto y complementar con este subwoofer para poder subir más el volumen total sin que distorsionara y funciono tal y como esperaba. Creo que este sistema está enfocado a reforzar los bajos de autos que tienen sonido de agencia, no para hacer vibrar las ventanas de los vecinos. Tamaño Me sorprendió lo compacto que es e incluso crei (por su tamaño) que no cumpliría con mis espectativas. Cabe debajo del asiento de mi auto y es casi imperceptible. Prácticamente no ocupa espacio y no estorba. Cabe recalcar que mi auto es muy pequeño y aún así pasa desapercibido. INSTALACIÓN La instalación será tan fácil como tu auto lo permita. En mi caso fue sencilla y no tengo experiencia en instalación aunque si tengo conocimientos de electrónica y herramientas. Solo necesitas conectar voltaje y fuente de audio, es todo. CALIDAD DE AUDIO Si tus espectativas son moderadas entonces tiene un buen sonido, es de cajón sellado por lo cual lo hace carecer de las frecuencias más bajas, pequeño precio a pagar por su tamaño tan compacto. Tienes que invertir un tiempo para ajustarlo a tus necesidades. CALIDAD La calidad de construcción es muy buena, es aluminio vaciado, lo cual le da mucho peso. El calor se dicipa en la carcasa. La parrilla que protege la bocina es de metal. EN RESUMEN Hasta el momento me siento satisfecho, hace lo que se supone y cumple con mis espectativas. No me gustó el led azul del potenciómetro, brilla demasiado, debieron utilizar un led rojo con menos brillo.

Easy install and powerful sound from a smaller subwoofer
Originally purchased the SSL 8 inch sub but got too frustrated trying to install with high level inputs that would not power the sub on. Purchased this Rockville sub and the install was a breeze and the thing sounds amazing in my 2025 GMC Canyon. Fit seamlessly behind the back seat and my truck rocks. The bass is enough to rattle the rear view window and the back seat. Would buy another one of these any day. Well built and you can tell by the weight of the sub. Five stars!
