...im 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 BASS10 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 BASS10 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.
Specs - Dimensions: 14” x 12.3” x 3.3”, Weight: 11.35 lbs. Phase control. LED status indicator. Thermal, Short and Overload Protection Circuits. High ....
