MTX subwoofer CF10AT45

You would need an amp kit to do the install correctly. This includes all you would need for wiring the amplifier portion. Do you still have the factory Monsoon radio?? If so you would also need a line level converter. The MTX thunderform does have a high level inputs but they don't sound as good as the low level RCA input. I used the speaker level inputs on an MTX thunderform in a Explorer once and it just sounded muddy. Used a line level converter and sound was much better.
