I have a sony system and it has 2 speakers and 1 subwoofer. The sony mini hi-fi system has the speaker ports for the sub and the 2 speakers. I also have another 2 speakers I want to hook up to the system. Is there a way I can wire this or buy something cheap to split the connections in my receiver so I can have all 4 speakers and the sub work at the same time on 1 receiver. Please Help!!!
You can wire the speakers in parallel or series, depending on the amplifier and the speaker impedances. If the amplifier can drive a 4 ohm speaker on each channel, and you want to put two 8 ohm speakers on it, just connect them in parallel - that will approximate a 4 ohm speaker (be sure and connect the + to the + and the - to the - ). If the amplifier is rated to drive only 8 ohms, then you can either wire 8 ohm speakers in series, thereby approximating a 16 ohm speaker. This will minimize an over-current situation, but will result in a small, inconsequential mis-match which causes a small amount of power to be lost (it won't be noticeable w/o a sound meter). If the speakers are 4 ohms then wire them in series as well to produce an equivalent of 8 ohm impedance.
