Yes you can, but you will be working at almost maximum voltage of +-45V. The TDA7250 chip will get slightly hot, so best to put some heatsink on it.

I run mine at 2*27 - which works out to +-35V. This is the recommended working voltage. No heatsinks necessary for chip.

With a 650W transformer, you can run 3x TDA7250. Just nice for a 6 channel HT amp.
