[QUOTE="gamehawk55, post: 8226139, member: 645990"] Hey guys so I just got my HO alternator in. It's a 6 phase 310A (180A idle) build from Mike over at Singer. But I am still having massive voltage drop issues while only running 1500W or less to my subs. I'm running 2 SA-8v2 D2 off an RF T2500-1BDCP (tuned accordingly). Stock battery 1 year old (yes I've tried a brand new one and it made 0 difference) 0 Gauge Shok industries reference series CCA wire for main run to rear and BIG 3 All my grounds are 0 gauge and measure 0.3-0.4ohms (can't seem to get any better than that) I'm going to link a video from my dropbox of just how bad the drop is. On this amp the voltage gauge is on the right and when the needle drops to center that is 12.5-12.8v and yes it's accurate. Something is SEVERELY wrong because there is no way I should be seeing this bad of drop on 1500W with these upgrades to my electrical.
