Skar Audio VD-8 Subwoofer vs Skar Audio SDR-8 8" Car Subwoofer

Both are 8-inch dual 2-ohm Skar subs, so the real split is mounting depth and power handling. The VD-8 is the shallow-mount pick: it fits doors and tight boxes where the SDR-8 will not, and it carries a higher 400W RMS rating. The SDR-8 is a conventional-depth sub with a higher peak figure but lower RMS, so it suits standard sealed or ported boxes on modest power. Owners of Skar's shallow line praise the fit and output for the size; the SDR line is a budget staple but the 700W number is peak, not continuous.

• Choose the Skar Audio VD-8 if you have limited mounting depth, such as a truck cab, door panel or shallow box, and want the higher 400W RMS rating.
• Choose the Skar Audio SDR-8 if you have room for a standard-depth sub and a box built for a conventional 8-inch driver.
