We were doing this back in the 70s with whatever 2 channel source would handle it plus the added speakers. It's not decoding surround but as it was explained back in the 70s it does give you some cool audio effects from the difference in the stereo channels, IIRC it was phase difference that contributed to the "new" sounds you'd hear. Note: this hack is NOT the reason I no longer have a working Pioneer SX-980,
inch for inch a Golf, not an unproven model (leaf) encroached or compromised trunk space (energi, volt) and more-than-commuter range. $21K with the rebates - that's less than a GTI. This is a huge opportunity for VW. If my commute gets below 80 miles I'm getting one.
