Hi Chris,
I am only happy to hear from you.
Yes, a problem is the either cold+rainy or terribly hot + dry with risk of fires. I prefer spring or in particular autumn with much less tourists and reduced prices. More moderate weather.
When you make an amplifier, you should always check the DC-offset at the outputs before connecting the speakers. With BTL, the two amplifiers for each channel can leave important offset and temperature drift. An offset servo may be useful but is rarely implemented for ordinary amplifiers.

The datasheet, Figure 17, only shows a version with symmetrical supply. You will have to design a virtual ground circuit for pin 9 yourself.
Figure 17 shows a BTL coupling. As rail-splitter (virtual ground), you may consider TLE2426 from TI as long as the supply voltage does not exceed 40V.
