LOPRO10 Powered Under Seat Car Subwoofer - 1200 Watts Max, Single 2.6 Ohm, Voice Coil, Built in Amp, Low Profile, Remote Subwoofer Control

Built-in Amplifier - With a MOSFET power supply, you achieve enhanced switching speeds, superior performance with reduced power from the driver, decreased gate-to-drain feedback capacitance, and lower thermal impedance for higher switching frequencies. Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes above the filter's frequency setting. It is primarily used to keep high notes out of your subwoofer(s). High Level Inputs - Speaker level inputs are often called high-level inputs. They are utilized to connect the unit to a factory radio or an aftermarket radio that lacks low-level (RCA) inputs. Low-Level Inputs - Line level inputs (RCA inputs / low-level inputs) employ RCA interconnect cables to link the unit with the source unit. Many aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers. Variable Bass Boost - Variable Bass Boost enables you to adjust the low bass within the boost range according to your preference. Specs: 15.5 x 11 x 3. If you have limited space, this is an excellent solution. The combination of amplifier and subwoofer into a single unit makes this perfect for vehicles with spatial constraints. Weight: 13 lbs. Professional installation is advised to ensure proper and safe operation. Please verify this model is compatible with your vehicle before purchase
