1 / 5
The Rockford Fosgate M1 8" DVC 2Ω Color Optix™ Marine Subwoofer delivers respectable bass from a small, easy-to-place package suitable for boats, RVs and tight installs. It can perform on low-power head units and sometimes without an enclosure, but it may not satisfy those wanting deeper output and there is at least one report of premature failure.

Based on customer reviewsCompact marine 8" sub with surprising low-power punch
The Rockford Fosgate M1 8" DVC 2Ω Color Optix™ Marine Subwoofer delivers respectable bass from a small, easy-to-place package suitable for boats, RVs and tight installs. It can perform on low-power head units and sometimes without an enclosure, but it may not satisfy those wanting deeper output and there is at least one report of premature failure.
What buyers praise
- Compact size fits tight spots in boats, RVs and ceilings
- Delivers good bass even on low-power head units or small amps
What to watch for
- Won't match the deep output of larger subs (users sometimes prefer a 10" instead)
