One standard feature that buyers should be pleased to find on every 2006 Hyundai Accent is the 172-watt audio system. The stereo uses six speakers to provide surprising sound quality for a base unit in a sub-$12,000 car. A single-disc CD player is also standard. However, buyers looking for additional watts and more CD slots will have to venture into the aftermarket, as the Hyundai Accent’s options list is devoid of any audio upgrades.
