Media Source

Powered by an Alpine D800, the head unit directly decodes audio information from Compact Discs, USB thumb drive, iPod or even 3.5mm stereo jack into digital PCM – and sends them to the audio processor via Alpine’s optical link.

It is also possible to add a bluetooth module, so that music can be streamed from your smartphone, using Spotify and even default Music players and also make handsfree calls with it.

The Alpine D800 is also a multimedia station that is able to decode and stream Dolby and DTS from DVDs or iPod Movies to the processor.

The steering wheel controls functions normally, controlling volume, track actions (such as forward, backward) as it were with the original head unit.

Audio Processor & Amplifier

The Alpine PXA-H800 processes audio information from the media source and sends the signals over a 4V analog output (RCA) to four Ground Zero Reference 2PURE amplifiers.

The four amplifiers were meticulously gain matched using scientific methods to the audio processor’s 4V analog output to preserve the proper signal-voltage ratio and ensuring zero distortion and imbalance in the signal chain.

Providing up to 16 channels of 420W @ 4 Ohms per channel and operating variably on Class A and AB, the amplifiers powers 4 types of speakers discretely.


The finest speakers made by Ground Zero, mounted on custom fabricated speaker enclosures on the A-pillar of the vehicle and aesthetically matched to the car’s interior design.

  1. Ground Zero Reference 28mm Tweeters on A-pillar
  2. Ground Zero Reference 80mm Mid-Range on A-pillar
  3. Ground Zero Reference 180mm Mid-Bass in doors
  4. Ground Zero Reference 250mm Sub-Woofer in sealed enclosure mounted in the trunk built to calculated size.
