Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 in the contiguous US. Approved returns may be subject to a restocking fee.
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.

When the rest of your car audio system is built to a high standard, the XS Power 557 battery terminal hardware ensures that the connection at the battery lives up to the same expectation. Engineered for XS Power AGM batteries, it accepts large ring terminals and battery cable lugs cleanly, forming a tight top post terminal connection that resists loosening through vibration and temperature cycling. For builds where consistent, reliable power delivery is the baseline requirement, this is the terminal hardware that delivers.
The 557 suits a broad range of applications -- from everyday street systems that run a heavy amplifier load to dedicated competition builds where every electrical joint is scrutinized. Choosing purpose-built car audio battery hardware means your system benefits from proper engineering all the way back to the battery itself.
