Sundown Audio X v4 15 Single Bundle (Baltic Birch)
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 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. 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.

The Sundown Audio XV4 15″ subwoofer delivers extreme power handling with the advanced X v.4 coil design, rated 3,000W RMS and 6,000W peak for clean, distortion-free output at high volume.
