## Description

desertcart.com: Planet Audio P8AWK 8 Inch Under Seat Powered Car Subwoofer, 8 AWG Wire Kit : Electronics

## Features

- Built-in Amplifier – Low-Profile Subwoofers that are amplified do not need an external source and are generally very compact
- MOSFET Power Supply - 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 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 & Low Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
- Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
- Variable Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
- Phase Control - Phase control lets you adjust the speaker phase with the amplifier depending on the location of the subwoofer. This will avoid possible sound cancellation depending on the setup
- Specs - 12.2” x 8.9” x 3”, 8.8 lbs.
- 3 Years parts and labor
