[QUOTE="n2audio, post: 8692265, member: 540940"] Lower your carb intake and exercise more 😕 Seriously though... The electrical system literally revolves around the alternator. The purpose of the battery is to start the car, and power the accessories with the engine off. Otherwise the alternator carries the electrical load. Extensive aftermarket electrical accessories sometimes dip into the battery as a reserve because they exceed the alt's output or they demand too much current too fast for the alt to respond in time (like 1000w+ worth of bass). Your stock alt is sized to power the stock electrical system, maintain the battery's charge, and last ~100k or so. When you add electrical load that 100K is reduced because the alt will run hotter and wear out faster. Adding a battery may help the amp run a little better by reducing voltage sag when the alt's output is exceeded, but it will not reduce the load on the alternator. Your options are either find an HO alt that can keep up with the demand, or expect to replace your stock alt every year or so. [/QUOTE]
