Paralleling AMP9
 
I would like to parallel my amp9 for more volume. I currently have four 4 ohm speakers (110db horns), rated at 60W max, each connected to one channel of the amp. I want to replace those with four 8 ohm speakers, rated at 100W max, in parallel, and parallel the amp into 2 channels. I am running the amp on a 25v battery.

So...
To parallel the amp and connect to paralleled speakers...
Channel1+ to Channel2+ to SPeaker1+ and SPeaker2+
Channel1- to Channel2- to SPeaker1- and SPeaker2-
and
Channel3+ to Channel4+ to SPeaker3+ and SPeaker4+
Channel3- to Channel4- to SPeaker3- and SPeaker4-

1) Is this wiring right?
2) Does this give me 200W each for the 2 newly paralleled channels (still 400W total output)?
3) Two 8 ohm speakers in paralled gives me 4 ohms, so can I expect to still get my power rating for 4 ohm load (about 65W at 1%THD+N and 25V, 100W at 20%THD+N)?
4) Each speaker can see the 100W, right?

Thank you very much for the feedback!
