Whether you’re in your car, UTV, boat or riding your motorcycle, any audio enthusiast appreciates a powerful amplifier. As cars get smaller and we install stereos into a wider array of vehicle types, one thing remains constant: smaller amplifiers will become more prevalent moving forward.

This fact hasn’t been lost on the product development team at Rockford Fosgate. In fact, they have developed a series of “Motorsport” amplifiers – small footprint, high power units designed specifically for these more difficult installations.

In this review I'm looking at the top of the line, four channel amp in the Motorsport line, known as the Power T400X4ad. Loaded with innovations and several patented features, this extremely compact amplifier is rated at 100 watts per channel into either four or two ohm loads, and has a U.S. suggested retail price of $499.99.
