Hi, iam Craig Wind, Asalam walekum.

Can I Hook Up 4 Speakers To One Channel? [Solved]

The easiest and a safe way to connect 4 pairs of HiFi speakers is to use a 4 zone speaker selector switch. This is relatively simple to wire, just run a wire from the central location (lounge room) to each speaker. The box should also look after any impedance matching to prevent amplifier overload.
