I'm thinking of using it as a monoblock, http://www.velleman.be/kits/k4005.htm
But. I'm a little confused about the power ratings and impedance.
The powerrating is very critical. If you bridge this stereoamp into mono, you get 200 watt and then you need +/- 30-35 volt, impedance can't go under 8ohm.
But if I want to drive 2Ohm load, can I just put a large resistor in series with the output?
My second question is; Can I drive them with less voltage then specified? Like +- 20 Volts
Any answers are very welcome!
Best Regards, Christian

Christian,
I have had a bad experience with this product, and I have reason to believe that my problems are not a one-off.
Have a look at this thread:

You would be much better off using this kit:

The specs on the opamps are nasty. If you are goning to spend the money on a kit, get your moneys worth. This will be more expensive but I think it may be worth the extra money.
