## Overview

The Rockville SS65P is a compact 6.5" powered subwoofer delivering 400W peak power with a slim 2.83" profile designed to fit under car or truck seats. Featuring built-in amplification, versatile input options, and advanced sound controls including bass boost and subsonic filtering, it offers professional-grade bass enhancement without sacrificing space. Durable with multiple protection circuits, it’s engineered for easy installation and reliable daily use, perfect for millennials seeking premium audio upgrades that blend seamlessly into their lifestyle.

## Description

The SS65P is an all in one solution to give you great sounding bass in your vehicle without taking up a lot of space. This powered sub enclosure is only 2.83" thick so that it can easily fit under your seat! This is our smallest sub in this series but it packs incredible technology. Compared to our 8” in this series this 6.5” actually sounds just as good! We use a higher powered amplifier in order to get the 6.5” to have the same SPL and sound quality as the larger version. 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 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. The SS65P 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 metal 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: Amazing underseat subwooper - I installed this to my montero sport 2019. I cant ask for more. Amazing product. Worthy to buy.
Review: Great choice - I installed in my F150 2016 2 doors stock infotainment system installation required 8 gauge wire and RC connect or speakers wire ( that doesn't come with it ) It adds that boom sound missing in stock speakers clear load enough and invisible under seat It won't shake your car and others can hear it , if you fully upgrade your sound with amplifiers I think it's not the right choice But if you are looking for music that you only enjoy descent sound with little upgrade on speakers then look no further
