Stereo signal distribution

Hello Guys,

I wanted to drive 6 speakers from 3 stereo audio amplifiers. Audio input will have to be same for all 3 amplifiers. Audio source I'm having is my mobile phone. The doubt I'm having is, can I distribute audio signal to all 3 amplifiers from my mobile's 3.5mm jack? If I do so, will it lead to clipping of audio signal or should I use any other circuit in between my 3.5mm audio output and amplifier's input? Please share your valuable suggestions.
 
A headphone output has a low output impedance (in the order of ohms) while the line input of an amp will have a much higher input impedance (in the order of tens of thousands of ohms).

Even connecting the phone to three amplifier input impedances in parallel shouldn't appreciably attenuate the audio signal or load it to the point of distortion.
