Small Sub. Serious Bass.
The DC Audio M4 6.5" Subwoofer proves you don’t need a massive enclosure to get deep, clean bass. Built for tight installs in cars, trucks, or Squarebody builds with limited space, this little monster delivers 300W RMS and 600W peak while maintaining DC Audio’s signature sound quality.

Perfect for single-cab trucks, rear cargo panels, or custom enclosures behind your Blazer seats — this sub brings low-end authority where full-size woofers just won’t fit.
