The DEH-4500BT's in-built amplifiers produce pristine sound delivered at 4 x 50W of pure, proven MOSFET power. If that isn't enough, you can always use the RCA pre-out to hook up another stereo component, like an extra amplifier for the rear speakers, for example.
This car stereo is specifically designed to play music stored on your portable device. The front panel's illuminated USB and Aux-in gives your iPod, iPhone, Android smartphone or USB stick a direct connection to your car speakers via the DEH-4500BT's sound system. The additional iPod Direct feature lets you control your iPod or iPhone from the dashboard of your car.
