## Description

BOSS Audio Systems BASS8 8 Inch Under Seat Powered Car Subwoofer – 800 High Output, Low Profile, Built In Amplifier, For Truck, Boxes and Enclosures, Remote Subwoofer Control

Review: Great option for a budget setup - Good option to add to a budget or stock car audio setup. Won't impress anyone but it fills in that missing thump and low end. Do note that this doesn't come with any of the required wiring, so make sure to pick up a wiring kit (I got some cheapo kit here on desertcart for like $12, just make sure its at least 10 gauge) and I wired directly into the rear speaker wire. Out of the box it's set to a base non-tuned setting so won't sound good at all - you NEED to tune and adjust the settings on both the sub and your head unit. Read the manual, it explains how to set the gain. I think I ended up somewhere with the gain set to 3/4, bass boost almost near max, and the high pass filter a half or turn up from middle (this is important if you're regular speakers don't produce a lot of bass). I also turned down my head units "bass boost" setting from +3 to +1 as the regular speakers don't need to try and fill in bass anymore and let them shine more in their minds and highs.
Review: Bueno - No es tan potente, es para un carro prqueño y que el sonido vaya bien con ese pequeño bajo

## 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.

### ⭐⭐⭐⭐⭐ Add Bass
*by C***R on 26 May 2023*

For the price of this sub, it's great. Added some much needed bass to my truck. By all means your not gonna win a sound competition with it. But if your looking to add some much needed bass to your vehicle, this is it. They do have a higher priced ones such as the bab8 n the 4k one. They may give better bass but I have no experience with those models. But great sub. Will b buying another to add to the truck. But I would suggest buying the wire kit also. Makes installing it easy.
