  • HIGH LEVEL INPUTS: Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the LOPRO8 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
  • 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)
  • BUILT-IN AMPLIFIER: With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies
  • VARIABLE BASS BOOST: Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
  • LOW LEVEL INPUTS: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the LOPRO8 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
