High-end audio systems have unique power demands to perform — and our accessories for Audison car batteries will keep them juiced up. We carry hardware such as the Audison Superfarad car stereo capacitor, which stores backup electricity for your Audison car amplifier. If the amp ever outdraws the electrical system, the battery capacitor kicks in, so you don’t overload the battery. Shop for other accessories such as negative battery terminals and clamps that have a 60-day money-back guarantee.
