Okay, so I have done a TON of research, and pretty much narrowed my isolator choices to the following:

or
http://hellroaring.com/bic75300.htm
The difference is that the NewMar one has a continuous voltage of 100 AMPS
The Hellroaring one has a continuous voltage of 150-180 AMPS
My audio system has a 851watt amp. I also have 2 6x9's, a surround sound receiver, and my tv / dvd player in my dash. My alternator outputs about 130 AMPS. Im not an electrical engineer and know nothing about amps, etc, which one of these isolators is the best for me??
