BATCAPS
Something I hadn’t heard of until very recently,but basically a very small battery with the discharge characteristics of a capacitor,so the best of both without the disadvantages of either.
These don’t need a split charge system as you would if you were running a second battery,but are wired directly across the amp’s power terminals,and so effectively always in parallel with the car’s alternator and chassis battery.In fact they are said to be able to supply enough current in short bursts to be able to crank a small engine should your chassis battery not be able to,something a powercap could never do as it would be fully discharged in well under a second.Real world tests have shown them to increase the voltage and current available to power hungry amplifiers,so taking some of the strain off the cars original electrical system.
