If it helps at all By my calculations with a 3000w Amplifier with Subwoofer resistance of 2 Ohms, plus another smaller amplifier for speakers the amp draws would peak at 70A. The ONLY 100 UTV designed Battery Isolator Avaliable w/PEP Lithium Only For LITHIUM Batteries At least one of your batteries should be Lithium Stronger. FlexMod Smart Battery Isolator Controller.
