The Amplifier Is Built In, So Installation And Wiring Is Clean And Simple. This Is A True All In One Subwoofer Solution With The Subwoofer Built Into The Enclosure Along With A Top Of The Line Amplifier Built In As Well. We Focused On Making Installation A Breeze So We Designed This Unit With You The Customer In Mind. We Added High Level Inputs So You Can Install This To An Aftermarket Or Factory System. The High Level Input Allows You To Install This Even If You Have No Preamp Outputs Available. The Smart Turn-On Circuit Will Sense That An Audio Signal Is Present And Turn On The Amplifier. When You Turn Off Your Music Signal The Amplifier Built Into This Subwoofer System Will Automatically Turn Itself Off. Something Else We Did To Make Installation Quick And Easy Is We Put All The Inputs And Outputs On One Side. This Makes Wiring Neater And Easier. Our Competitor'S Models Are More Challenging To Install. The Ss8P Has 400 Watts Of Peak Power And 100 Watts Rms. This Has Great Controls So You Can Adjust The Sound To Your Liking. It Has A Level Control For The Volume And Subsonic Filter To Filter Out The Really Low Frequencies Which The Human Ear Cannot Hear. This Also Has A Low Pass Crossover Filter, Phase Control, Input Sensitivity, And Bass Boost. Included Is A Remote Bass Knob, And Mounting Hardware But The Best Thing About Our Model Is The Sound. It Is Slim But It Sounds Like A Full Sized Subwoofer If You Are Not Happy With It We Will Offer You A 90-Day Money Back Guarantee. If You Don'T Like The Sound, We Will Send You A Pre-Paid Label And Refund You In Full!.

### ⭐⭐⭐⭐⭐ Review
*by F***O on 27 October 2019*

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.
