This receiver makes your car audio system expandable. The pre-amp outputs allow you to hook up external amps for your speakers without needing to purchase additional accessories. Since this has 3 sets of pre-amps you can hook up multiple amplifiers. This has front, rear, and sub pre-amp outputs so you can amplify all your interior speakers, and add a subwoofer amplifier. This receiver utilizes 5V - preamp outputs. Since this has 5 Volt preamp outputs you will get more power out of your external amplifiers due to the high voltage signal.
