Planet Audio P10AW 10 Inch Powered Under Seat 10 + No Wire Kit, silver

Built-in Amplifier – Low-Profile Subwoofers that are amplified do not need an external source and are generally very compact

Passive Radiator – A driver unit that has its motor structure (magnet) removed, becomes a passive diaphragm. As a result, there is no Chuffing that you would generally get with a ported box, thus enriching the BASS & making the system more linear

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 P10AW to your factory radio or an aftermarket radio that does not have low-level (RCA) input

Low Level Inputs - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the P10AW with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
