Nothing at that link for me, but if done properly they'd be using the Prius' battery, IOW the type of high power audio split system I have long been advocating but without the front-end SMPS PSU. The advantage is being able to get 5kW of audio output (RMS of course!) into 8 Ohm speakers even using their later lower 200V system. To output 4kW off their st'd 12V system adds much inefficiency, plus of course requires a larger ~400A alternator for continuous running, or 12V battery replacement every 20 minutes (if that), or extra 12V batteries.

On the link it said then drive train wasn't modified so doesn't that include the alternator https://www.youtube.com/watch?v=R13nF0OQZEU&feature=youtube_gdata_player Here's a YouTube video1993 sdv

The 12V electrical system in a Prius is like the 12V system in any other car...Support the12volt.com

Right but an half electric based car can support a 4k system without any charging system upgrades1993 sdv

Your link is dead but I watched the Youtube video. No where do they say the electrical system is un-modified, and I'd be very surprised if someone was going to build a highly modified show car like that one they would not upgrade the electrics. Also, calling a Prius a 100% electric car is BS, of course... Nice fiberglass work I will say.Support the12volt.com

Here's another link I found it says how the builder didn't say if the drive train has been modified or not but he did say he added four batteries http://www.wired.com/autopia/2008/08/the-worlds-most/1993 sdv

Drive train = motor and tranny. I wouldn't assume it meant accessories hanging on the motor.Kevin Pierson

OK Cuz I saw the factory battery and accessories and I couldn't compute how it was done1993 sdv

It's probably as I described. It would be illogical to do it from its 12V system. Besides, as I recall, the Prius has no 12V alternator. Its 12V battery is charged via a ~50V (dc-dc) converter from its main battery.
