## Description

Product description Break Your Subwoofer In Much like the engine of a new automobile, a new subwoofer must go through a short but important process of “break-in” before it is run under harsh conditions. The “break-in” process will ensure the subwoofer is able to perform as it has been designed to. This process involves subjecting the subwoofer to no more than low-to-medium volume levels for a number of hours in the enclosure. 3-4 hours is generally sufficient for the subwoofer’s suspension to loosen enough to prevent the voice coil(s) from overheating and causing failure. The break-in period is also effective in extending subwoofer life. Over-driving the woofer before it has been properly broken-in will usually result in premature failure and poor performance. 800 Watts Peak Power, PWM MOSFET Power Supply RCA & Speaker Level Inputs Low Pass Filter, Bass Boost Phase Control, Remote Subwoofer Control LED Status Indicator Thermal / Short and Overload Protection Circuits High Performance Voice Coil Rubber Surround Built-In Amplifier Systems with a built-in amplifier do not require the addition of an external amp. They already have the power to play louder. High and Low Level Inputs High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units. MOSFET Power Supply Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. Class A/B Amplifier Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency. Variable Low Pass Filter Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer. Variable Bass Boost Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it. Variable Gain Control The Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly. Low Profile Low-profile subwoofers are a great choice for space-constrained areas without compromising on power and performance.

Review: Big sound, small package! - This little thing really impressed me. I needed some stronger bottom end power in my 2012 Nissan Pathfinder. I have a Kenwood DMX8709s installed with a pair of Kenwood 6x9s in the front, and they sound good, but they distort at higher (or even mid) volume with bass turned up even a little bit. That's where this sub comes in. I wired it under my driver's seat and while it did take a minute of time to adjust my EQs and crossovers to remove the bottom end load from my speakers and onto the sub, it does an amazing job. Sound is crisp and tight even when turned way up past normal listening volume. In terms of the type of audio quality, I would describe this sub as tight and punchy. It doesn't hit the extremwly low frequencies that you might get from a proper ported sub enclusore (20hz or so), but it does much better than full range speakers. It seems to respond down to about 25hz, but it gains quite a but more response above 30hz. If you're listening to hip hop and expect street rattling bass at nearly inaudible low freqiencies, this isn't the sub for you. If you want premium audio system sound *inside* the car that you can feel and that suits virtually every other genre of music very well (seriously, everything from jazz to metal to chill beats sound amazing) and you don't want to sacrifice cargo space, this is where it's at. You will need to spend some time tuning EQs and crossovers, but it can be made to sound awesome. I can't believe it's this small and this cheap. I haven't attached the included brackets because it sits comfortably nestled when wedged between the seat anchors which allows me to slide it out of I want to make adjustments and it doesn't move when the vehicle is in motion. I picked up a boss 8 Guage wiring kit and it worked perfectly for my application. Great work Boss! Super happy with my purchase. Any thoughts I had about potentially returning it before I installed it are entirely gone.
Review: Great for what it is! - If you are looking for trunk rattling bass, this is not for you. But, if you are looking for a compact powered sub that will add some great low end to your ride, this is it! I got one for my son for Christmas and it worked so well I bought one for my car a month later. It won't rattle your trunk, but it will definitely annoy the neighbors if you turn it up. The bass is clear and crisp. Great value for the money!

## Features

- Space Saver - If you are tight on space, this is a great solution for you. The combination of amplifier and subwoofer all into one, makes this ideal for spatially challenged vehicles. With a slim design, there are a few installation options
- Pulse Width Modulated - PWM simplifies power supplies. It controls the output voltage and current precisely by not only removing the output current sensing loss, but also eliminating all secondary feedback circuitry. Efficiency. Increased reliability
- Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
- High Level Inputs - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the BASS8 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
- Low Level Inputs - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the BASS8 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
- Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
- Phase Control - Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up “out of phase”
- Specs - Dimensions: 12.20” x 8.86” x 2.95”, Weight: 8.82 lbs. LED status indicator. Thermal, Short and Overload Protection Circuits. High Performance Voice Coil. Rubber Surround. Aluminum Cone, Remote Subwoofer Control

### ⭐⭐⭐⭐⭐ Fits in an escape
*by C***N on December 23, 2025*

Sounds great. Definitely gives that extra bump. Fits nicely under the back seat of my 16 escape. Not enough space to put the seat down so I just put it under the smaller half. Tuned right it's loud bun not obnoxious
