Installed in my 2009 Crown Victoria, this radio works perfectly with the Ford factory subwoofer. Low frequencies are sent to the subwoofer and the rest goes to the front and rear speakers. The full system sounds really good once you get the settings dialed in (fade, bass level, etc.) CD6 is easy to use and the OEM fit of the radio is flawless. This unit is highly recommended if you have the factory subwoofer in your CV or GM. Also, Replacement Radios came through with fast shipping and excellent customer service!
