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 either a highly technical HDPE resin rotational molding or hand laid fiberglass process to create lightweight, durable enclosures often matched to your interior and available in three formats: amplified, loaded, and unloaded.
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 subwoofer that is either standard depth (TN) or shallow mount (FPR). These models can be used with existing amplifiers or with upgraded amplifiers.
Unloaded models work with most 10" or 12" subwoofers, depending on model, that you already have or that you want to use with an upgraded subwoofer.
