My alternator is a 200amp powermaster that makes 14.7 volts.
With adding a 6 volt to the system behind the seat, I am getting 18.4 volts with the truck turned off, and 20.7 volts with the truck running. I was installing some new 4 awg wire today to upgrade from my 8 awg and decided to go ahead and put the 6 volt in line, and the results are just as he said they would be.
If anyone wants some drawings on how to do it themselves, just say so, and we'll post them.
Ultimatly, I have my normal battery hooked up the my trucks charging system like it's supposed to. I have a 4awg wire going from the positive of my 12v battery, to the negative of the 6v battery. I then have the positive of the 6 volt battery going to my amp, and the amp is grounded to a seat bolt. Now, I will have to randomly pull the battery out to charge it, but man, this is one awsome redneck fix to get more watts out of the box.
Thanks ww228kidd for recommending this. This is working awsome. I'm putting 20db on base station buddies of mine 14+ miles away with a 1x4 competition-style amp.
There's a forum member on here named BushHog that works with me that can verify the volt output

Just all FYI. Enjoy.
