Hello,
A lil bit of confusion here.
So I have 2 amplifiers, both providing an AC signals from a single function generator. The AC signals coming out of those amplifier is in range of 4 Amps (dont ask why ).

I have to distribute these 2, into four individual signals (I have splitters) of 2 Amp each, but with a phase shift of 45 Degrees.
So it will look like four signals @ :
1) 2 Amps @ 0 deg
2) 2 Amps @ 90 deg
3) 2 Amps @ 180 deg
4) 2 Amps @ 270 deg

I am thinking that due to the large current a simple RC circuit might burn.

Any idea on how should I go on about doing this?

A large inductor could achieve a phase-shift near 90° (which would be frequency dependent). A transformer can provide a phase-shift of 180°. A transformer and the inductor could provide a phase shift of near 270° (also frequency dependent).

Otherwise you could add additional amplifiers with an active phase shift circuit at the input to each amp.

What is the frequency of the signal?
