Watts delivered is a function of the voltage times the current. If the amp was 100 percent efficient, it would need 33 amps at 12V for 400 watts. At 14.4V, it would only need 28 amps. Of course, amplifiers are NOT 100 percent efficient, only about 50-60 percent in many cases, but somewhat higher for monoblocks, maybe 80-90 percent. So you're looking at a fuse in the 60-80A range. In the absense of a specific fuse size from the manufacturer, I'd start the primary fuse at a 60A and if the amp blows it on power up/immediately/frequently, move up to an 80A.
All of the Rockford-Fosgate 2-channel bridgeables I've ever seen show using the left positive (+) and the right negative (-) for bridging. But if it's not shown right on the amp, I'd call or email RF for the correct connection. The new amps do show it.
Hope this helps.

for a test
disconnect everything from the remote terminal in the amplifier
get a bit of wire and connect the remote terminal to a 12 volt supply
does it turn on now?
if yes then check the remote wire from the radio does it become 12v when the radio is on and 0v when it is off
if no make sure that the amplifier has been grounded properly and all the power cables are connected properly
