Speaker series wiring

[MPDIEHL]

If you wire them properly....YES
Follow this ....... + (from receiver) to + (on your first speaker) - (from your first speaker) to + (on your second speaker) - (on second speaker) to - (on your receiver)
That will have them firing in proper phase with each other.
Im assuming you have two 4 ohm speakers you want to use and this will be appx. 8 ohms showing at the receiver.
