I wish to connect two power amps together. Do I use parallel on both amps
and control volume on the bottom amp?

In general, paralleling modern transistor amps is a good way to start a fire.

You can bridge some amplifiers, but not all. Bridging gives you twice the
voltage output, but no more current, so if your goal is to drive lower Z
loads, it won't help. But if you need to sink more power into an eight-ohm
load with amps that can drive four ohms, bridging is the way to go.

What are you trying to do?
