I am about to change my amps. I currently have dB Drive A7 75.4 and dB Drive A7 1500.1. I am getting Orion XTR 4000.1 and Orion XTR 1700.4. I am getting a dual alternator bracket/belt setup. Having a pair of 160a stock alts rebuilt at a local place that does some pretty nice upgrades for a good price. Nobody local has ever had a bad experience, so I'll give him a shot. Under my hood I have a stock location battery (behind driver headlight) and I have the tray to put one on the passenger fender. Should I put a stereo battery there, like an XS D4800? Or should I put it in the bed, closer to the amps? For the amps I am going Dual 1/0 inputs on each power and each ground. on each power lead pair I will have a 2 way fused distro block. This will give me 3-1/0 runs for each amp, giving me 1 spare lead for whatever else I may add. This is the distro Im referring to. https://www.ebay.com/itm/KnuKonceptz-KNF36-2-Way-1-0-Gauge-Fuse-Distribution-Block-Dual-1-0-Out-w-Fuses/380701568113?ssPageName=STRK:MEBIDX:IT&_trksid=p2055119.m1438.l2649 So, with that being said, battery and battery location is what I need opinions on, truly. I was considering the Kinetik HC3800 batteries too. From the alt, I think I will run a pair of 1/0 for the charging leads. Will it suffice, or should I go dual 2/0? I do NOT park n play my systems. I play when driving. I mute at stop lights n such. When people so ask to hear, I do demo, but thats RARE. Just want to get it straight before I install the new XTR setup.
