DiBo Posted September 28, 2018 Report Share Posted September 28, 2018 1 hour ago, Twistedmister said: Do you think one more d925 setup would do it? No. That amp is really a 4.5k in 3k clothes. Your alternator is fine but you'll need around 250+/- ah of battery reserve total. Minimal. More like 275+. Then you'd be good to go imo. Get an AGM front battery also. Doesn't have to be xs power. Bosch Platinum, duralast Platinum, exide Platinum... How many runs do you have from front battery to the back battery? Go with 2. Out a 300 amp fuse on each power. 2 about a foot or so from the front, 2 about a foot or so from the rear bank. Electrical is crucial for high amperage draw equipment.
