Default tda7294 in bridge config

Hi, How can I get 400W (200W per channel) with TDA7294? As I understand, only 7293 allows parallel conection to add more power to the output, how you do it with this one?.

Can I use TDA7293 in place of TDA7294 ? Because I have a 35-0-35 ac transformer which is = +/- 49v dc . maximum voltage for TDA7294 is +/-40v.

Your 35-0-35Vac transformer may give out as high as +-52Vdc.
