Thank you Scott...I was worried about starting a fire.

I want to get more power to two 12" speakers with an 8 Ohm load. My amps put
out best at 4 Ohms. It's for rehearsal and the 200 watts stereo from a 4 Ohm
amp to 8 Ohm speakers is not loud enough to do vocals over all our noise.

So use parallel?

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?
