Description
MMATS Pro Audio Juggernaut Series III
Juggernaut is the top end of the MMATS subwoofer lineup for builds where output capability, motor strength and thermal capacity take priority over compact packaging. This is the line for serious street-SPL and competition-level systems—not a casual stock-electrical upgrade.
Why we carry it: when the enclosure, amplifier and charging system are all being designed as one package, Juggernaut gives us a platform that can keep up with very high power without forcing the system into a generic one-size-fits-all subwoofer.
Current size choices
- 10-inch HO: compact high-output option for bagger and tight-space builds. MMATS directly confirmed this HO version at $549.99.
- 12-inch: strong balance of cone area, enclosure size and output.
- 15-inch: more displacement when the vehicle and enclosure can support it.
- 18-inch: maximum cone area for large-format SPL systems.
Before choosing one
- Final coil configuration must be matched to the amplifier and target impedance.
- High-output Juggernaut systems require charging-system, battery, wiring and fuse planning.
- Enclosure alignment matters as much as amplifier power; a poor box will waste the capability of the driver.

Where this fits in the build
The subwoofer is only one part of the bass system. Enclosure volume and alignment, final impedance, amplifier power, vehicle space and electrical support all affect the result.
