DD Audio 2508G-D2 8 Inch 1200 Watts RMS Dual 2-Ohm Competition Subwoofer

This listing includes

• (1) 8" 2-Ohm Subwoofer 2508G-D2

Eight inches. Zero compromise.

The DD Audio 2508G-D2 takes everything oversized and compresses it into a brutally efficient footprint. The latest “g†revision brings upgraded motor force, smarter cooling, and a suspension system that behaves like it’s been to the gym twice a day.

Perfect for tight builds that still demand competition-level output and precision.
