depending on wiring man,and what your amp can handle. get an amps, then wire the speakers to the lowest the amp can handle.
With a 4 channel amp he should be looking at one for one meaning each speaker has it's own channel.
He could split the input (from the head unit to the amp) and I doubt it would make any difference since the amp, and not the head unit, would be loaded by the speakers.
