DESC: It's pretty amazing how far car receiver technology has progressed since the days of 8-tracks. Take Pioneer's DEH-2100. This detachable face CD receiver balances affordability with flexibility, and succeeds on both counts. If keeping the setup simple is a priority, then you'll appreciate the built-in high-power MOSFET45 4-channel amp. Contour your soundscape with Direct EQ - you'll get 3 preset EQ curves plus "flat." Supertuner III's outstanding reception quality makes listening to the radio a real pleasure. You'll have no trouble finding stations, thanks to travel presets and seek tuning. When you're ready to expand your car audio system to get more volume and punch, you'll find a set of rear preamp outputs for hooking in a component amplifier. Press the loudness button for robust, full-frequency sound at low volumes.
