How Should I Amp Everything Up?

[nsta]

Hey guys, i just bought a new amp for my splitsand 12" pioneer sub, i need to know the best way to amp everything up.

Basically, i have some really nice 90w rms splits (180w rms total), they are infinity references 1020cs's midrange+tweeter fronts (which i want to amp), and i also have a pioneer 12"sub/box which i want all connected to my 800w amp. Whats the best way to run everything???, my headunit has only 1 rca pre-out, but my amp has 2 pre-ins(4 channels), as you can see in the pic, i was told to buy splitters, and run each rca to 2 channels on the amp(which in turn makes it 4 channel), thus i can use all four channels of my amp(is this correct)???

Anyway, my main concern, is i have a rear channel and a front channel on the back of my amp, which channel should i amp the splits to, and which channel should i amp the sub too, and will the split's internal crossover allow me to still have my high frequencies, or will i need to set the crossover on the amp to allow for this????

Splits to Front channel with HPF on if desired, not required as you already have splits which have their own cross over network

Sub to Rear, bridged, LPF on set to around 80hz, no bass boost

ez..
