high voltage systems

has anyone had some experience with high voltage systems like an 18 volt system?.... i know how to reach 18 volts but i just wanna know the effects of it on the car and on the whole system.....

effects on the car -- You'd HAVE no car.

It would have to be an entirely different circuit than the 12v system that your car requires.

i know that its a whole different circuit but what do you use for your charging of your charging system to the car

you'd have to have 2 alternators - one at 14v powering your car and charging the regular battery. Another at 18v powering the stereo and charging the 18v battery/batteries.

You can use 2 alts like n2audio describes or you can simply use a 16v charger. Standard 300amp 12v wheel chargers will do as well, but strain like mad if you have a large battery rack.

Most people I know just series 2 8volt batteries together, and the batteries typically float when fully charged at ~17.5v or so. Keep in mind that the 16v battery bank will need to be grounded to the frame and share a ground with the external HU which should be running at 12v.

Also the REM+ should be 12v as well.

does the 12v and the 16v gounds and sharing them on the same frame going to disrupt anything?

Nope.

The battery rack should be grounded to the vehicle and thus should share a ground with the HU which is running on 12 volts. This allows the amps to turn on with only 12v at their remote turn ons...//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif So actually it is kina required. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
