A Pioneer DEX-P99RS was chosen for its clean looks and great DSP. It was installed where the factory CD changer was behind the closable door. The factory radio still functions as well, for the phone, navigation, warning sounds etc.

The front doors were treated with Dynamat Sound deadening on the inner and outer skin. And the 6" Dynaudio midrange / woofer was mounted in the factory location with a custom mounting ring. The smaller OEM midrange was retained for the factory phone and Nav voice.

We opted for four old school JL Audio 10" free air woofers in the rear deck to retain the entire trunk and still get unbelievably accurate bass reproduction inside the cabin.
