Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

The XS Power D3478 is a no-compromise Group 34 AGM battery built specifically for vehicles running demanding audio systems on a 12V electrical platform. Its sealed absorbent glass mat construction means it can be mounted in virtually any orientation — a critical advantage when you are reclaiming every cubic inch of trunk space for enclosures and amplifier racks. With deep-cycle capability married to a massive cranking figure, it satisfies both the vehicle starter and the audio system without splitting duties between separate batteries in simpler builds.
The AGM Standard for Daily-Driver Builds
For a street car running a big amplifier array alongside a high-output alternator, the D3478 is the kind of high output battery that soaks up the charge and hands it back without sagging. SPL competitors use it as a front battery anchor precisely because its sealed AGM design is safe in the cabin, and daily drivers love that it doubles as a legitimate dual purpose starting battery with impressive reserve capacity.
