Space Saver - 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. Embrace the Bass..
Built-in Amplifier - A built-in 800 Max watt amplifier powers the subwoofer.
Pulse Width Modulated - This design controls the output voltage and current precisely by not only removing the output current sensing loss, but also eliminating all secondary feedback circuitry. It increases efficiency, is lighter, smaller reliable.
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 Input - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the BAB8 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs.
Low Level Input - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the BAB8 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 t....

1,000 watts of power packing all the performance of a larger bass box into a more compact design that’s lighter and easier to carry.
Line output EQ can be set to a high-pass filter or full range, allowing for easy crossover selection when used with a main loudspeaker.
Two 10-inch high-excursion drivers built into a compact enclosure that’s light and easy to transport.
F1 Model 812 extension bracket integrated into the subwoofer can be raised and lowered, allowing the F1 Model 812 Flexible Array loudspeaker to be safely mounted on the subwoofer, eliminating the need for a conventional pole mount or tripod stand.
Polarity switch with selections for NORM and REV. Reversing polarity allows for easy correction of low-frequency overlap between the main loudspeaker and subwoofer.

Space Saver - The combination of a built-in 300W amplifier that powers the 8” subwoofer makes this ideal for spatially challenged vehicles..
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. Adjust it from 50-150 Hz to best fit your system..
Ease of installation - Takes either speaker wire (High-level) or RCA cable (low-level) inputs. This makes connecting the QBUS8P to your radio easier since it's compatible with both factory AND aftermarket units!.
Automatic Turn-On - This circuit automatically turns the QBUS8P on whenever it senses an audio signal. This eliminates the need to run a remote turn on wire making installation a breeze..
Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it..

Support two input, one AUX input, connect wired analog signal input.
another one Bluetooth wireless input, can connect with mobile phone, computer and other Bluetooth devices.
Support the frequency adjustment of the subwoofer, you can adjust the bass frequency according to your needs.
support the bass frequency adjustment of the left and right satellite boxes, making the left and right speaker output more playable.
in addition, the left and right speakers can also be used when the subwoofer is not connected.
Two pieces of TPA3116D2 , one for the left and right channel output, one for the subwoofer output, the Bluetooth part adopts the imported CSR8635 high quality Bluetooth receiver, and the internal uses 4 NE5532 op amps, 3 of which can be plugged and unplugged, which is convenient for customers to change different styles. Op amps, increase playability.
