Description
The DC Audio M3 Level 1 12-inch subwoofer is designed for sealed or ported car-audio enclosures. Its double-stacked motor and 2-inch voice coil provide a focused bass upgrade without requiring the installation space of the larger DC Audio platforms.
Key specifications
- 300 watts RMS and 600 watts peak power handling.
- Stitched paper cone, stamped-steel frame and spring-loaded terminals.
- Mounting depth: 6.5 inches; mounting-hole diameter: 11.2 inches.
- Manufacturer enclosure suggestions: 0.75 cubic feet sealed or 1.25 cubic feet ported.
System planning
Choose the listed dual-voice-coil option to suit the amplifier and planned series/parallel wiring. Confirm enclosure dimensions and account for the driver, bracing and port displacement rather than treating an outside box measurement as usable airspace.
Recommended Monoblock Amplifiers
Power-matched options for one subwoofer or one complete loaded enclosure. We aim to include same-brand choices when their ratings qualify.
Loading amplifier suggestions…
Suggestions use 75–125% of the subwoofer’s RMS rating at the wiring load shown. Check wiring, enclosure needs, electrical capacity and installation space. Set gain and filters correctly to avoid overpowering the subwoofer. Buying more than one subwoofer changes the match.
