Shuriken Marine Batteries & Accessories

Shuriken is a brand of electronics mothership Metra, whose scions include Axxess Integrate, Raptor, Ballistic Sound Suppression, Tsunami, Install Bay installation hardware and the Metra Home Theater group, etc. They also operate the Installer Institute for car audio technicians. With this big a footprint in the audio industry, it's no small wonder that they know what's required to manufacture a superior-performing line of auxiliary batteries.

Marine audio has an enormous appetite for power. Your vehicles' charging system wasn't designed to handle it. A few inefficient speakers, constrained to operate out of small enclosures need plenty of watts to make the kind of sound levels we crave. Just running a fat wire to the battery helps, providing a path to the amps with little voltage drop, but that only means you can run the battery flat in less time while parked with the engine off.
