People say that and here I sit with that Amplap Aurras set at 4,000 watts, 68ah AGM single battery under the hood, NO battery in back, with 1/0 of course and a 320 amp alternator and at idle at full tilt sits at 14.7 and the lowest on certain bass drops 14.0 and within a millisecond it rebounds to 14.7. Gotta love those Tractor Supply AGM'S at 150 bucks a piece
and the J&S 320 amp 4G alternator for 379
. No issues running 4,000 watts and no issues with everything keeping up! Granted Korean vs Half-Bridge but even then the SIA was doing the same thing at 3,500 watts. Never at 14.0 for more then a millisecond.
