Default 100w into 1.3ohms

Does anyone know of an amplifier that can produce around 100watts into 1.3ohms.
It is for a sub-woofer I recently got of a friend, it is a SONY SS-WP1000.
The Specifications are attached go to page 57 on the PDF for more specs.

Thanks

If that's what stated on the back, it must be correct
Not very consumer friendly though....

As I recall it's a part of a cinema system, so maybe Sony used a Class D amp to drive it.............

A class D car-audio subwoofer amplifier would be fine. Standard linear amplifiers are not designed to drive such a low impedance in an efficient way.

Connecting the outputs of a 4 ohms stereo amp in parallel with two 0.5 ohm resistors might work, make sure you use resistors that can handle enough power.
