Upping the Current in the STi

Due to the abundance of audio, video and multimedia products we've crammed into the Subaru STi, the standard battery needed to be swapped out for something a little more... powerful. Kinetik HC Power Cells are used in the "Worlds Loudest Vehicles" and provide a very low ESR and high energy density. We opted to use Kinetik Power Cells as they are acclaimed for being the most powerful, reliable and compact car audio power cells on can buy.
