Big Bass, Small Space — Done Right.
When space is limited but performance matters, the DC Audio M4 8" Subwoofer delivers. Designed for tight enclosures and built to take serious power, the M4 8 bridges the gap between small-format convenience and full-size output.
With 800 watts RMS and 1,600 watts peak, this little powerhouse hits low, stays clean, and handles everything from daily driving to competition-level abuse.

Why Choose the M4 8"

• True Long-Throw Design: 19mm of Xmax and a tall-roll stitched surround for extreme excursion.

• Built to Handle Power: 2.5" copper voice coil and gap-cooled motor for superior heat dissipation.

• Heavy-Duty Construction: Bolted-down spaced spider pack keeps movement linear under high power.

• Low-Frequency Precision: Oversized cast frame and high-roll surround reproduce deep lows with accuracy.
