Product Research

Features

Vehicle Compatibility: This ThunderForm custom-fit, amplified, pre-loaded enclosure is designed specifically to fit the 2000-2014 Ford F-250 Super Cab pickup truck.

Mounting Location: Then enclosure mounts under the rear bench seat. The vehicle's jack stays in its factory location and the tools are relocated to under center of enclosure.

Molded Enclosure: The molded, high-density polyethylene resin enclosure resists flexing and dampens resonance.

Dual 10" Terminator Subwoofers: This enclosure comes loaded with dual 10" MTX Terminator woofers. The woofers have an unusual impedance, specifically designed for the amp, and cannot be replaced with a standard MTX model.

Class D Amplifier: The enclosure contains a built-in 200-watt Class D (digital) amplifier that allows RCA or speaker-level input. The amplifier is highly efficient and designed specifically for use with the subwoofer in the enclosure.

Built-in Low-pass Filter: The low-pass filter frequency can be varied from 50 to 150 Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle.

External Bass Control: The external bass control allows you to adjust the bass level from anywhere in the vehicle.

Auto Turn-On Feature: When the speaker level inputs are used, the system will automatically turn on and off with the radio.

Note: The auto turn-on feature does not operate when the preamp level inputs are used, unless the remote turn-on lead is connected.

Tool Required For Installation:

  • Powered screwdriver
  • Wire cutters
  • 6" Bit holder extension
  • #2 Phillips head bit
  • 5/16" Wrench

Q
Does this come with a wiring kit/amp install kit?
ronald  Oct 16, 2020

A
The power and ground cables are included. Also included is a 3 foot remote turn-on wire. You may need a longer turn-on wire and cables to get the audio into the bar. We have advisors that you can reach by calling 1-800-324-9695 who can discuss your system and give a recommendation on the extra parts needed to complete the install.

Q
Can you use an external amp to power the subs?
cameron  Nov 03, 2018
1 answer
A
You cannot because this box only has inputs to get power and audio into the built-in amp. We should a custom subwoofer box like this one that doesn't have an amp built in so you can use an external amp to power it. I recommend contacting an advisor on 1-800-324-9695 to check your pickup My Bio: https://www.crutchfield.com/bio/Paul

Thanks for your question. It is a Class D Amplifier: The enclosure contains a built-in 200-watt Class D (digital) amplifier that allows RCA or speaker-level input. The amplifier is highly efficient and designed specifically for use with the subwoofer in the enclosure. This information is from the main product page "Details" tab. Hope that helps.
