Vault Power Battery Guide

Vault Power battery support can help a car audio system stay more stable when the build needs more current than the stock electrical system can comfortably provide. SMS Car Audio helps plan battery support around the amplifier demand, vehicle, wiring, fusing, alternator support, and future upgrade path.

This page is a planning guide. Exact battery specs, chemistry, fitment, charge requirements, and install requirements should be verified before purchase.
