MTX Thunderform Vehicle Specific Custom Enclosures are designed to take advantage of the unused space in your vehicle. For over 20 years MTX has been manufacturing 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 highly technical trained staff to ensure that your experience is more than you expected.

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

• Amplified models include an integrated high efficiency amplifier and dual custom subwoofers 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 dual custom 4Ω, 200W RMS subwoofers that can be used with existing amplifiers or with upgraded amplifiers.
