100w into 1.3ohms
 
2 Attachment(s)
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

Forget the part about the PDF just look at the thumbnail.

Where did you get the 1.3 Ohms from :confused:

Powertimes_2 28th October 2007 08:20 AM

The back of the sub-woofer case.

I don't think that Sony would put a product on the market that would frie allmost all commercial amplifiers ??
Can you post a picture of the back of the subwoofer case ?

Sorry cant get a pic, but this is what is says

SONY (R) MODEL NO. SS-WP1000

SPEAKER SYSTEM

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

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

Powertimes_2 28th October 2007 08:52 AM

yeah its part of a Cinema System

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.
