I run a small 350W rms 12" sub of a 2 channel amp bridged, it's not the best. It goes well, but there's so much more potential. Or you can bridge a powerful 2 channel amp, depends how many ohms stable.

1. if install another Power Amp, 4 channel... how the setting should be?
2. what type and size of speaker cables better to use...
