Often called a power cap or stiffening cap, some people prefer caps over secondary batteries. A second battery
is great for high power systems, but should be accompanied by an upgraded alternator that can efficiently charge
both batteries. This gets expensive. A cap stores power too, but can charge and discharge in a fraction of a second,
depending on size. While great for transient peaks in music, it does not have the stamina that a battery has and is not
an equivalent substitute.
Our Cap Cells are a fusion of both products. The Cap Cell offers auxiliary power with the ability to enhance the
transient notes, often suppressed in car audio systems with an OEM battery, while being able to reinforce the battery
during long, intense bass notes. A second alternator is not necessary, making the Cap Cell a perfect addition
and an affordable way to supply the necessary power for a system.
