tomorrow i plan on running a dump truck battery in my friends f150 to power his hifonics brutus 2000wt at 1ohm, i think he has an interstate under the hood, but for right now he wants to run a (something like 950cca) dump truck battery in the rear....i know he'll need 2 fuses at the front and rear....but will he need an isolator, whatever that is?
