Dafaseles Posted August 12, 2022 Report Share Posted August 12, 2022 If the battery is going under the hood, just get one that fits in the spot well. If it's a secondary battery, just make sure it's the same chemistry as the battery under the hood. In car audio, we're mostly looking at amp hours (ah). So the higher the amp hours an AGM battery is, the better for what we use it for. How much wattage a battery can support depends greatly on the size of the alternator. 2 80 ah AGM batteries with a stock alternator can't compare to 2 80 ah AGM's on a 350 amp alternator. 2011 Chevy Silverado under construction My build log here.
