Pre-Order Nowbr For a complete sound system upgrade without all of the hassle, the Lynx Audio SW-836D is the best solution. It is an 10" active subwoofer inside a sealed sound box with a built-in 860W 4.1 Channel amplifier to boost the power output to all four speakers in your car. The system will not only add powerful and accurate bass to your vehicle and will also provide more power to all of the speaker components in your car giving you more crisp and clean midst and highs for an overall louder and better quality sound in your music. The best thing about this is that it will take half of the time it would normally take to install all of the audio equipment to get the same result. The system comes complete with a pre-wired power harness that makes the installation go very quickly and easily without having to worry about installing all of the separate wiring that is normally required for a subwooferamplified installation. Speaker level inputs and RCA inputs allow convenient connection to just about any factory or aftermarket stereo system. The system also includes a wired gainfrequency control remote to allow you to have complete control of how much bass you want in your music.
