This is Audison's direct fit kit for Golf 7. Included is the following:
• Audison Front door midbass Speakers
• Audison 8.9Bit amplifier with built in DSP and Time Alignment
• Audison Direct fit 10" 900 watt Subwoofer + box 
• Audison Direct fit ( No-Cut ) wiring harness

Barry also wisely upgraded to new front Audison tweeters and front door sound proofing to sharpen / improve the sound even further. 
This system from Audison sounds so good and really sounds like a system costing twice as much...
