Can you do better than Tesla's sound upgrade for less money in the aftermarket? Teslarati compares Tesla's upgraded speaker system (a $2,500 option) to a system from Light Harmonic. Upgrading to the $999 Light Harmonic Model S.4D provided mixed results. While not as complete as the factory upgrade, the speakers seem to be of a much better quality than those that come standard in the Model S. As a complete system, Tesla's Ultra-High-Fidelity Sound is better, but still, it's $2,500, and the aftermarket option is a pretty good deal. The author and his team note that a true head-to head comparison can't be made until Part 2 of Light Harmonic's upgrade is released. Also helpful, Teslarati details the process of switching out the speakers at home, with some tips on how to make it easier for yourself. See the video above, and read the full review at Teslarati.

ClipperCreek's new Share2 system allows two EVs to charge from the same circuit. If one car is plugged in, it gets full power, but plugging in a second vehicle will split the power between them. "This enables customers to charge two vehicles at the same time, on one branch circuit, saving considerably on installation costs," says ClipperCreek President Jason France. ClipperCreek is offering Share2 on its HCS-40 line of Level 2 chargers. A two-station bundle with Share2 starts at $1498. Read more from ClipperCreek.
