[QUOTE="ethik, post: 8783615, member: 685357"] Thanks everyone. Bass boost is off and I am not getting any dimming. It sounds like I need to do two runs of 1/0 gauge OFC from the front battery positive to either the amp input or a rear battery. If I add a rear battery should I use a shared chassis ground for the amp and rear battery or ground them separately? Do I need a 300A fuse 12" or less from each amp positive input? Do I need an isolator for the rear battery? Is there a cheaper battery option instead of the JY HP-40? What do you think of the JP40? [URL]https://www.down4soundshop.com/down4sound-d4s-jp40-12v-lithium-battery-6000-12000w/[/URL] How much worse off would i be if i just upgraded the wire and didn't purchase a second battery? Thanks [/QUOTE]
