[QUOTE="Ed Lester, post: 4786742, member: 587479"] The 81000D and 1501D is a very efficient amp and I have run one from a single optima yellow top and stock alternator and still made full power from the amp with no ill effects. This amp is not rated at 1 ohm but can certainly run 1 ohm. I found the most power came from .7 ohm loads. A strapped pair at 2 ohm made over 4400w per coil in my setup. Each amp was making 2200w at 1 ohm. The Crunch GP2500Ds are rated at Max power and will make about 1250w each. These 2 amps will operate just fine from a single large battery like the Kinetik HC2400 or Power Master D3100 or 2 medium batteries like Optima Yellow tops. It will not be necessary to upgrade the alternator to charge these batteries since they will charge easier than your stock battery. [/QUOTE]
