For over 20 years MTX has been manufacturing Thunderform vehicle specific custom enclosures that are designed to be installed in space that would otherwise go unused in your vehicle. All models are made in our manufacturing facility in Monroe, WI by our MTX technicians to ensure that your experience is more than you expected.

All Thunderform models are manufactured using highly technical rotomold or fiberglass processes to create lightweight, durable enclosures that are available in two formats: amplified or loaded.

  • Amplified models include an integrated high efficiency amplifier and custom subwoofer that deliver an exceptional performance with easy installation. Mounting hardware and amplifier kits are included in each model to make installation easy.
  • Loaded models include a custom 4Ω, 200W RMS subwoofer that can be used with existing amplifiers or with upgraded amplifiers.
